Athletes & Muscle Gain: The Problem and the Solution

Competitive athletes need to lift to prevent injuries and enhance sports performance. Weight training is the best way to build tissue resilience – increasing muscle, tendon, ligament, and bone integrity. And of course weight training enhances strength and the explosive ability to tackle, jump, cut, sprint, and hit.

Training methods that don't serve these purposes don't have much use. BOSU balls, neon-colored dumbbells, and single-leg stability ball overhead squats (exercises with too much going on) are not efficient or effective.

However, if training methods serve both injury prevention and performance enhancement, then you should build your program around them. Building maximal strength, using full ranges of motion (most of the time), correcting movement patterns, and getting strong in all planes of motion are the ticket to making long-term progress.

This can help you clear up a lot of programming confusion. But there's still one question it fails to answer: If you're interested in explosive power gains, should you train for hypertrophy (muscle gain) or should you train solely for strength, power, and speed?

The Problem with Most Hypertrophy Training

Typical hypertrophy training has a few features that are needed to optimize muscle gains:

  • High volume. In general, more volume (sets x reps x weight) leads to greater size gains. The volume should be a mix of the next two hypertrophy mechanisms.
  • Mechanical tension. The greater the load, and the greater the active range of motion, the greater mechanical tension.
  • Metabolic stress. Metabolites must be built up in the muscle from lighter, longer sets of high reps.

So, a typical scheme looks something like 3-5 sets of 6-15 reps at 65-75% load.

This combines high amounts of volume, mechanical tension, and metabolic stress for gains. Train a few days a week, eat in a caloric surplus, recover well, and you'll gain muscle mass.

However, there's an issue. With a typical set of 10 at this intensity, velocity decreases with each rep. Less velocity (at the same load) means less power. And over time, low power training isn't the way to preserve or optimize athletic power. In fact, this is a recipe to DECREASE explosive power.

Hook Grip

The Solution: Cluster Hypertrophy Training

The fix is simple: Do fewer reps and more sets. Instead of doing 4 sets of 10 reps at a 65% load, do 8 sets of 5 reps at a 65% load.

By lifting in this manner, power output is maintained. Volume is the same (40 reps), mechanical tension is the same (65% load), and metabolic stress is maintained to a degree. To preserve time, you'll only need about 60-90 seconds of rest with 8x5 instead of 2-3 minutes of rest with 4x10.

Another added benefit of cluster training is the maintenance of mechanical performance and quality of work. This means no more grinding, sloppy reps which can set you up for injury and ingrain bad motor patterns.

The Study

The short-term benefits are pronounced, but what if this is taken long-term?

Jonathon Oliver et al put this to the test, and after 12 weeks found a greater increase in power, a greater increase in strength, and similar lean mass gains in a cluster group vs. a traditional group. In other studies, clusters showed greater volume load (as traditional got so fatigued they had to drop weight).

So, if you want to preserve and optimize explosive power during hypertrophy training, look no further than cluster training.

Hypertrophy Train for Explosive Power

Do 8x5 or 10x4 at 65-75% load with 60-90 seconds rest. Use this set/rep scheme for the major, compound exercises (squats, deadlifts, pushes, and presses).

For assistance exercises, use a variety of rep ranges. This can improve strength and endurance better than sticking to only one rep range as well as stimulating different pathways of growth.

With hypertrophy clusters, you get all the injury prevention and performance enhancement benefits with none of the downside of traditional size training. You can gain muscle, get stronger, and increase explosive power all at once.
