High Rep Training

I’ll start this post off with a video I first saw years ago.  Here is the legendary Tom Platz doing high repetition squats with heavy weight (well over 500 lb).  This video was filmed back in 1993.  Tom Platz and Dr. Fred Hatfield (aka “Dr Squat) were doing a “squat off” in Germany.  Hatfield won the one-rep max competition by squatting 855 lb.  Platz won the rep competition with the weight you see here:

A while back I wrote an article on the best rep range for building muscle and burning fat.  I basically argued that a 5-10 rep range is going to be ideal for both of these goals.  I still believe that–most of your gains will probably come from this range.

But more advanced and older trainees may want to consider experimenting with higher repetitions (let’s say 15 and up).  There are some good reason to do so:

I’ve heard several bodybuilders say they had better leg growth from training with higher repetitions.  This makes sense because the quadriceps in particular tend to have a high number of both fast-twitch and slow-twitch fibers.  You’ve just seen what Platz was capable of in his prime–his legendary thighs were built with both heavy lifting and high reps.

Joint Health

High rep training has the advantage of being able to stimulate the muscles with less strain on the joints.  Older trainees in particular may find this to be very helpful.  But even younger guys can benefit from simply giving the joints a break.

Lactic Acid

Training with higher reps will produce more lactic acid, which in turn tends to produce growth hormone (a helpful hormone for burning fat).

Mental Toughness

I’ve found that training beyond my usual rep range also helps me learn to push beyond the pain barrier and force my body to keep going when my muscles are screaming to stop.

Variety in Training

Going to the gym can get kind of boring if you do the same thing week after week.  Dropping the weight and going for higher repetitions is a simple way to challenge yourself and keep things interesting.

Research

Some recent studies indicate that training with high repetitions is an effective way to build muscle.  One study, for example, took fifteen healthy young men and randomly assigned them to different workouts, measuring their bodies’ responses to different training stimuli: 1.  One set to failure with 80% of one-rep max (1RM)  2.  Three sets to failure with 80% of 1RM, and 3.  Three sets to failure with 30% of 1RM.  Needless to say the third workout tended to be much higher in repetitions (20-23).   They found that lower weights/high reps produced a similar anabolic response to lifting with heavier weight and low reps.1 This is just one of many studies you can find verifying the efficacy of this kind of training.   Bottom line: training heavy is not the only way to build muscle.

These are just reasons to consider incorporating higher reps into your workout.  Now let me give you some practical tips (in no particular order of importance):

Exercise Selection:  I think you’ll find some exercises simply aren’t good choices for high reps.  I love deadlifting, but I rarely go over 5 repetitions for that particular exercise.  My form simply starts to break down if I try to go beyond that.  The same goes for front squats.

I tend to be old-school and prefer free weight exercises, but it may be advantageous to consider machines with this kind of training–especially if you are working out without a spotter.

Time Under Tension:  Using less weight will mean you can lift more slowly and deliberately.  Take advantage of this and maximize the time your muscles are under the tension of the weight.

“Burnout” Set:  One of my favorite techniques is to finish my training with one or two sets of high reps after I’ve done some heavier sets.

I hope you find these tips helpful.  Try them and see if they don’t produce new gains.  Please check out my list of recommended workout programs if you’d like more detailed training guides.

Eccentric Training: Negative Overloading for Hypertrophy

I remember doing concentration curls back in the early days of my training.  I was in the high school gym and an older teammate on the football team gave me a tip.  He advised me to slowly lower the weight over a count of a few seconds.  This was my first time to hear about “negatives.”

I’ve learned more about this kind of training over the years. Mike Mentzer believed in emphasizing the eccentric/negative part of the repetition.  He advocated doing a few slow negative reps at the end of an all-out intense set.

One advantage of this method is maximizing time under tension–the amount of time the muscle is under the stimulus of a given weight.

Overloading the negative repetition is another variation of this technique.  Here’s the idea: you can resist more weight than you can actually lift.  Let’s say you can bench press 275 lb.  Chances are you could slowly lower more than that–probably well over 300 lb.  By doing so you would be putting 300+ lb of tension on your muscles, even if you can’t lift that amount of weight.

At least one study suggests this way of training is effective.  Forty male subjects were divided into five groups and trained using the leg press for 3x a week.  They all used the same percentage of their one-rep max during the concentric (lifting) part of the repetitions.  But each group used a different % of their one-rep max for the eccentric (negative part of the lift): 0, 33, 66, 100, or 138%.  Strength gains were the same in those using the 100% and 138% load for their eccentric training.  But only the trainees who overloaded the negative repetitions (the 138% group) gained mass in their legs (they were also the only trainees to increase bone mineral density).1

One if the biggest challenges with this kind of training is the need for a spotter on certain lifts.  But there is a pretty simple solution that can be applied to many exercises: lifting the weight with two arms/legs, then lowering it with one.  This works very well on the leg press, for example.

We shouldn’t go crazy over one study or think of this technique as a “magic bullet.”  But it seems like it is worth a try if you are trying to break plateaus in your size gains.
