The H/L/M Program
(Compiled from the various writings of Casey Butt by Nick Zezza)
Full-Body (Pre-H/L/M)
Start off by training the same exercises fairly lightly three times per week to get your body in condition for that type of training.
Pick one exercise for each body part (Chest, Back, Shoulders, Legs).
Do 3 sets in the 8-12 rep range. Leave at least several reps short of failure for each set.
Example
-Bench Press
-Bent-Over Rows
-Overhead Presses
-Back Squats
EACH SESSION, add a rep to one set until you reach 12 reps on all sets. Add 5-10lbs of weight to that exercise and start over at 8 reps, building up as before. Once you no longer feel you can add a rep to one set three times per week (i.e. you are worried that you might not be able to complete all the reps, which shouldn't take long unless you are a rank beginner or started extremely light), add only one rep per week. You might try to add one rep to one set on Monday, but then you'd repeat the same workout on Wednesday and Friday with the same sets, reps and weight until going for another one-rep increase on the following Monday IF YOU FEEL LIKE YOU CAN - do not force your reps. This gives your body the time and practice it needs to adapt to the workload increase.
If your performance improves on a set that's a "vote" to continue the cycle, if your performance stalls or regresses on a set then that's a vote to change things around (rep ranges, break times, exercise selection, etc). If the "votes" say you've stalled for two weeks in a row then it's time to move on.
"Beginner's" H/L/M
On your first training day of the week, go near maximum on your sets.
On your second training day of the week, use 60%-80% of the weights (for the same amount of reps).
On your third training day of the week, use 85%-90% of Monday's weights.(Note: if Incline DB Presses are your main heavy day chest exercise and you recovery fairly quickly from them, then you might be able to use 80% of the weight on light day, and 90% on the medium day. For something like Squats however, particularly "power style", your lower back, hips and knees might need more rest and you'd only use 60% of the weight on light day.) When your Heavy day stalls for two weeks in a row then it's time to move on.
Intermediate H/L/M
Perform different rep ranges on the training days:
Day 1 - 5-7 reps
Day 2 - 12-15 reps (with 1-min breaks between sets instead of 2)
Day 3 - 8-12 reps
When you begin stalling on a day, back down. For example, if you're stalled at 100x7, 100x7, 100x6 on Mondays, go back down to 3*100x5 and build from there. If you do that, and build back up to 100x7,7,6 again (your performance didn't increase even after the deload), consider it a "vote" to move on.
You can move on at this point if you're bored, or, if you're intent on peaking with this exercise at a certain rep scheme (you really want to increase your Bench Press in the 8-12 range, and this scheme is allowing you to do so, even if your 5-7 rep day is stalled), then continue with it. If your Medium or Light day begins to stall just as the Heavy day has, though, then two of the three days (the majority) have stalled and it's time to move on.
(At this point, you can repeat all the above steps with slightly DIFFERENT exercises. For example, if you were doing Bench Press, Bent-Over Rows, Overhead Presses, and Back Squats, switch to Chest Dips, Chin-Ups, Behind-the-Neck Presses, and Front Squats. If you have enough experience on the "new" exercises, feel free to progress in an accelerated fashion. For example, you might try to add a rep to one set once per session. Once that stalls, perhaps try the increase every other session. Once that stalls, go back to progressing once per week as it was outlined in the first step of this guide. After that, you should be months or perhaps even years into the program depending on how much weight you started with each time through and how gradually you attempted rep/weight increases. Once you've completed Intermediate H/L/M with the new exercises, you can either repeat the process again with even different exercises (such as Incline Presses instead of Chest Dips), or the exercises from the first cycle again: Bench Presses, etc., or move on to the Advanced implementation.)
Advanced H/L/M
Perform different exercises and rep counts at each session over the course of the week:
Day 1 - Bench Presses - 5-7 reps
Day 2 - Dumbbell Pullovers - 12-15 reps (with 1-min rests)
Day 3 - Chest Dips - 8-12 reps
Try to add one rep to one set on each day.

Frequently Asked Questions
What should my starting weights be?
You can pick 75% of your 1RM and just do three sets of as many reps as you can do with it. In other words, you might get 10, 8 and 6 with 75% of your 1RM. Then you'd try to build up the reps over time... say 10, 8 and 7 next workout.
How much should I rest between my sets?
Take longer breaks of 2-3 minutes between sets on your heavy days, shorter rests of a minute or less on your light days, and 2 minutes rest between sets on your medium days. You could try getting a higher growth hormone release by resting only 1 minute between sets, but the decreased weight you'd then have to use would make it pointless.
How should I warm up?
Warm up based on the exercise - 2 warm-up sets for heavy exercises, 1 warm-up set for lighter exercises. You don't have to strictly time the warm-up set breaks. In the 8-12 rep range that usually means something on the order of 1-2 sets with roughly 50% to 75% of your top working weight for the day. That's for the compound lifts. For isolation stuff, one set with about 65% of your working weight is usually fine. In the 5-7 rep range, lifters typically use 60% and 80% for two warm-up sets.
Keep the reps low for warm-up sets (5 or fewer). There's not much use in warming up with higher reps - no matter how many reps you plan to do. It'll only result in some lactic acid build-up. You're better off adding in an extra set of 5 (or two) than doing higher-rep warm-up sets.
Should my increased rep be on the first set or the last set? In other words, if I'm doing 3*100x8, should next week be 100x9, 100x8, 100x8, or 100x8, 100x8, 100x9?
It's usually "easiest" to progress on the later set(s) than it is the earlier ones.
You also have to keep in mind that a one-rep increase in performance is approximately equal to a 3% increase in absolute strength. So going from an 8-rep failure effort to taking that to 9 reps is actually a very significant strength increase - too much to rationally expect on a regular basis.
Increasing a rep on your later sets, when you're already fatigued, isn't indicative of such a dramatic strength increase because recovery ability (ATP, CP replenishment, etc), is a large part of the adaptation.
This is actually part of the reason why advanced lifters do multiple sets and regularly increase by a rep only on the last set. In that case, that added rep might only be indicative of a 0.5-1% increase in performance, not an unsustainable 3% as would be the case if you added a rep to a fresh set every week (in the bodybuilding rep ranges anyway).
Is it better to perform the same exercises for different reps, or different exercises for the same reps?
It comes down to goals, experience, and abilities.
Training for peak strength and peak growth are generally two different beasts, often requiring different approaches (there's a big overlap there as well depending on rep range, the nature of the exercise (explosive vs. non-explosive, etc)).
For beginners and people interested primarily in strength development on a particular group of lifts, using the same exercises but cycling intensity/weights often works well. Oly Lifters train the lifts multiple times per week because they're after maximum progress on specific lifts. But they also aren't after any significant degree of hypertrophy. For instance, a lifter trying to improve a lift might do that lift several times a week at different intensities simply for a high volume of specific practice/training on that lift. In this case, H/L/M would involve more volume on the targeted lifts.
Short periods training the same exercises each day can sometimes give quick strength boosts because it's a type of specialization routine on these exercises - you're focusing all of your energy into only a handful of movements. However, most people will need to carefully cycle their training intensity each day (as outlined the the beginners routine article) or they'll hit a wall fast. Only the genetically very gifted can train the same exercises all-out three times a week. With proper intensity cycling even advanced trainees can grow using the same exercises three times per week (at the advanced level many prosper from using different rep counts on each of the training days, say 5-7, 8-12, 12-15).
For bodybuilding/hypertrophy purposes, H/L/M would involve a similar volume but greater variety, using different exercises at consistently moderately high intensity in order to stimulate hypertrophy each time. In this case, it's better to chose different exercises for the three days (except for short periods to provide variety). Keep in mind that this is assuming a lifter is past the beginner stage where they're going to grow quickly anyway and are better off concentrating on fewer lifts.
There's also a combination of the two. For example, heavy presses on Monday, lateral raises on Wednesday and medium presses on Friday. I find that sort of thing can often work well if you're primarily a bodybuilder, but also trying to specialize on a certain lift.
Of course, the lines aren't that clearly drawn, but that's the gist of it.
Whether you do different exercises each day or not also depends on your experience level and where you are in your training right now. Advanced trainees usually benefit from doing different exercises on different days, so that they don't overstress their joints. However, sometimes even advanced trainees can benefit from doing the same routine each day -- remember Reeves, Park, Schwarzenegger and many others reached the top of the bodybuilding world and built up largely or exclusively on these types of routines.
If you're going to use different exercises on each of the three days, then intensity cycling is done by the exercise selection more so than the effort you put into the exercises themselves. You do this by choosing exercises that stress the joints differently and with different loads. For instance, you could do Incline Presses on your heavy day, DB Pullovers on your light day, and V-Bar Dips on your medium day. You might go up to sets of 5-7 on your Incline Presses, sets of 10-15 on DB Pullovers and 8-12 on Dips. In that way, you'll save your joints, avoid overtraining and be able to hit the muscles hard three times per week. Benches, Inclines and Declines in the same week however, are very similar movements and unless you have big, robust joints you'll overtrain and plateau very quickly.
A similar example would be including Military (Front) Presses and Behind-the-Neck Presses in the same week. The two exercises should not be done with the same grip width or elbow positioning in order to avoid the two exercises overlapping too much. With BNPs, a wide grip (Snatch width grip) should be used while keeping the elbows back in order to place as much loading as possible on the side delts. With MPs, a just-beyond-shoulder-width grip should be used while obviously allowing the elbows to the front at the bottom. This is an Olympic Lift inspired technique (at least a pre-1972 technique when the press was still part of Oly Lifting) to get as much power on the lift as possible... without cheating or using the "Russian" style of course. Obviously, this doesn't erase the overlap between the two exercises because they're still both fundamentally overhead barbell pressing, but a wide-grip-elbows-back BNP is a significantly different creature than a shoulder-width MP to the front... to further that difference BNPs should be done with a slightly higher rep count (and slightly lighter weights are safer with that style of BNP since it really isn't suited to be a true "power" movement). Still, the overlap is there, but the style differences make one more of a strength/power lift and the other more of a "bodybuilding" exercise.
Which approach you take is your call, as each of them can work if you approach them right.
If I'm after maximum hypertrophy, could I simply make every session of the H/L/M routine a 'Medium' day, sticking in the 8-12 rep range, but allowing the exercises dictate the H/L/M pattern? Is it possible to recover from training this way in this rep range solely, without handling the heavier weights on a Heavy day, or the lighter weights on Light day?
Possibly. But depending on the implementation, your conditioning and your genetics it may or may not produce more hypertrophy than a more "conventional" H/L/M routine.
Hypertrophy can't be so easily broken into "5 reps is for strength, 12 reps is for endurance and 8 reps is for hypertrophy". Sure, theoretically that may be the intended focus of each rep range, with at least a reasonable scientific justification, and that may be traditional "wisdom", but in the long-term you'll often find that 5 reps, or even 12 reps, may build just as much muscle as sets of 8 reps. Some of the biggest drug-free quads have been on Olympic Lifters who practically never did more than 5 reps ...and look at Reg Park in the 1950s.
In addition, the whole purpose of the heavy day is two-fold...
1) To recruit the fastest twitch muscle fibers, and
2) To strengthen the joints, connective tissues and nervous system for lifting heavier weights.
So even if you want to go lighter because that's considered more "ideal" for hypertrophy, the purpose of the heavy day is to work with the medium and light days to promote growth and strengthening.
But having said that, you don't even have to do 3x5, 5x5, 3x3 or anything else thought of as traditionally heavy. Heavy day gets associated with lower reps because that's the appropriate day for it if you were going to do that sort of thing. I usually put the lower reps on heavy days as an example of that's when to do it, but you certainly don't have to. You can do singles, partials, lock-outs, one set to failure in the 6-8 rep range or whatever. In that case, make sure the weights are heavier than your medium day, but because you're only doing one set you should be able to handle more than the medium day when you do several sets.
What I'm saying is, heavy day must stay heavy, but you can't keep doing the same thing week after week or make the volume too high or you will burn out. Use variety to make it interesting and target what you need. Don't get caught in only one rep scheme forever. Rotate 2-4 week cycles of different heavy day schemes as you get more advanced to keep from going stale and keep progressing.
Keep in mind, many pre-steroid era bodybuilders and lifters (Reg Park, Steve Reeves, Eiferman, Ross, Kono, etc.) did stick to one rep range all the time and usually the same exercises every session as well - they'd simply adjust their effort level by how they felt. That ability to instinctively know what their bodies needed and could handle was not only critical in allowing them to train full-body three times per week, it's also what made them champions. Marvin Eder and Doug Hepburn also cycled their training loads to different degrees, with Hepburn being very structured about it and eventually winning the World Weightlifting Championship as a result. Most of what went on to become the Soviet system of periodization was taken from Hepburn's concepts. Kono cycled his loads, but more instinctively. Park went for broke all he could, ate like ten men and slept like a newborn to support that. So it's definitely do-able and definitely worked for those people. But those guys were conditioned for it, had natural healthy diets, and the most successful ones had great genetics to go with it.
The cycling ideas presented in the H/L/M program (heavy, light, medium - different exercises on different days) were pioneered by people like Bob Hoffman (who began prescribing something similar in the 1930s) and Bill Starr (who wrote about it extensively from the 1960s to present). Its design is a way for people to get the variety needed to continue progressing, but also to allow recovery for people who would normally hit a wall on a fixed 3-day/week full-body routine.
Of course, if you change exercises each session, but stick to the same rep range you're still building in a fair bit of variety into the program and that might be enough to allow you to keep progressing without grinding to a plateau.
[EDITOR'S NOTE: From my experience studying H/L/M, rep ranges are generally over-analyzed to death. The whole purpose of H/L/M is to provide nearly all the necessary rep ranges in one program. On top of that, different exercises are placed on the different days as well, providing even more variety. So even if you think you should be doing 8-12 reps on everything:
(1) Chances are, that won't last long anyway, because most productive exercises have some overlap as it is. Take Overhead Presses and Behind-the-Neck presses for example. Both are highly regarded as the best delt exercises. Someone may put their Overhead Pressing on Heavy day and Behind-the-Neck pressing on Medium day. If they are done in the same rep range, however, there is very little variety there and the muscles are essentially doing a very similar movement, for a similar amount of weight, for nearly the same amount of reps. This is just an example, and not true for all productive exercises (i.e. the ones we SHOULD be doing...), however there seems to be a trend (another example would be Squats and Front Squats).
And (2), Some exercises aren't even suited to certain rep ranges (for example, you wouldn't be doing DB Pullovers for 5 heavy reps; they are much suited to higher reps in order to provide a break from chest pressing while still bringing about a growth stimulus through fatigue-based training).
Remember the whole point of H/L/M: to provide variety in order to train hard and promote growth three times per week. The more variety provided by the exercises, the less there is a need to cycle rep ranges as well. For example, if you do deadlifts on your heavy day, and chin ups on your light day, the two exercises themselves are very different, in which the weight being moved are on quite different planes of motion (at least compared to the back squat/front squat example). In that case, one could essentially do the same amount of reps on both days. Before you go searching for "very different" exercises just so you can train in the same rep range, keep in mind that generally the best exercises are at least somewhat similar in terms of motions. In other words, bench presses are quite different than chest flyes. But chest flyes are definitely inferior compared to v-bar dips (which would have an overlap with bench presses). Trainees would be much better off including the most productive (generally compound) movements to include in their training, and cycle intensity accordingly depending on the need for variety.
Not to say that it's impossible to do the same rep range three times per week (after all, in the beginning of H/L/M
you are doing the same exercises in the same rep range), but the more advanced you get, generally, the more variety you need. Otherwise, plateaus will come much sooner and you're more likely to become frustrated and switch to something else (which might work for a while, but not in the long run).]
Why start with 8-12 reps?
The reason I recommend higher reps to beginning lifters is because I know most people are interested in bodybuilding and general fitness, not Olympic Lifting (in which case the recommendations would be different) and it's a safe place to start. During the first few months, strength and hypertrophy gains are made just as quickly if a person trains lightly as if they train heavily (shown many times in the research) - so it's more prudent (i.e. safe) in my opinion to start light, perfect form and do the traditional bodybuilding rep ranges.
Also, with higher rep, lighter work in the 8-12 rep range you're not riding as close to the edge of nervous system and connective tissue overtraining, so you don't have to back down as regularly... which in itself is another plus for hypertrophy.
I am increasing one set by one rep each training day. Would that progression slow down size gains if my body was re-cooperating faster than that schedule and I was physically able to increase more than that, or does that not matter for hypertrophy?
In the longer term of the overall cycle it doesn't matter - you're better off consistently increasing performance just slightly. If not, you'll plateau sooner and your gains will stop altogether.
So, if you hit 3*160x5 on week 1 and you get in the gym on week 2 feeling great, do you simply do 160x6,5,5 ... even if you feel like 3x6 is attainable?
Generally, yes. Holding back is actually the tough part for most people because they have a "I must work as hard as possible at all times" mentality.
The question really comes down to how fast you think you can advance. For how long do you think you can keep adding a rep to all 3 sets a week? If you started with 3x150x5, then 3x150*6, 3x150*7, etc, then in five weeks you'd be doing 3x150x10. The only way gains like that are going to keep going is if you started off very light - otherwise you'll quickly hit a wall and have to switch things up (and/or deload). In six months time you'll probably be no further ahead than if you just did a longer cycle of 5,5,5 - 6,5,5 - 6,6,5 - 6,6,6 - 7,6,6 - etc. Of course, if you did that, you'd probably start slightly heavier as well, because you don't need to leave as much room for aggressive performance increases each week.
Keep in mind, protein turnover happens at a snail's pace (at least as in a few weeks) so pushing all-out every day really isn't going to accomplish anything that ramping more gradually won't, as long as you end up in the same place in a few week's time. In the end, it's the average workload performed over several months time that dictates growth, not what you did on any given day. In that case, it's very hard to beat a one-rep per week type scheme because even though the individual workouts are moderately hard (but not all-out) the average weekly load over time is high because there's really no "down time". When added up over a period of time, you've lifted a lot of weight, probably the same or greater as if you started lighter, progressed faster and then deloaded. In the long term, in terms of how the body responds to its environment, that's what matters.
Sometimes you can ramp up more aggressively, but that's usually reserved for when calories, nutrition and rest are really good. In that case you might go for shorter 4-6 week cycles. But for "normal" life the one rep per week rule is easier to maintain and almost like clockwork in terms of getting you there in the long run... distractions and boredom can become factors eventually though.
