The Science Behind the Training Manual

Henneman's Size Principle

Motor Units in muscle that create force to create movement


Small and Large Motor Units

In a Nutshell...

  • Henneman's Size Principle points out the existence of small and large motor units in muscles
  • Small motor units are relatively weak and are recruited first when demand is placed on a muscle; Large motor units are relatively strong and are recruited last when demand is placed on a muscle.
  • Fatiguing motor units stimulates 2 key adaptations of motor units in muscles after recovery: Increased Muscle Size and Strength.
  • Small motor units fatigue after a long time, recover quickly when fatigued (after seconds to minutes), and grow only a little after recovering from fatigue: Large motor units fatigue after a short time, recover slowly when fatigued (after days), and grow a lot after recovering from fatigue:

What does this mean for your exercise?

  • For proper exercise, you should fatigue all motor units in a given muscle, from smallest to largest, quickly, or else your muscle's small motor units will recover before you fatigue large motor units. Quick fatigue is actually the best exercise!
  • This quick fatigue makes your workouts short. In total for all muscles in your body, this adds up to less than 15 minutes for a complete full body workout!
  • Because large motor units take days to recover and adapt, you should wait several days before exercising again, on average, a full 7 days! If you don't wait, you will actually overtrain, so rest up!
  • In Short: Step 1) Fatigue all motor units, from small to large, for all muscles in your body. Step 2) Give your body time and nutrients to Recover. Step 3) Give your body time and nutrients to Adapt with Increased Muscle Size and Muscle Strength. 4) Repeat.

With this knowledge you can...

  • Use this principle to properly exercise just 1 time per week for just 15 minutes!
  • Schedule your 1 weekly workout when nobody is at the gym and train, in privacy, with all the equipment to yourself!

  • crowded gyms
  • waiting for other people to finish with equipment
