Neuro-Muscular Development (NMD) for Legs

As an athlete, there are two different types of training. First is a bodybuilding style where your focus is primarily on the muscles. Performance doesn’t really matter in terms of building your speed, reactive ability, etc. What matters is that your muscles are getting bigger through high tension exercises.
Then there’s performance development. With this style of training the primary goal isn’t bigger muscles. Sure, you can enlarge your muscles with performance training if the parameters are right. However, when you’re training for performance you’re basically training your nerves. In other words, simply making your muscles bigger won’t make you explode off the line faster or jump higher.
Both types of training have their place whether or not you’re an athlete. For athletes, rate of force development (RFD) reigns king, as I mentioned in my previous post. RFD is your ability to quickly reach peak levels of force. This requires “nerve training.”
Now, gaining mass through a bodybuilding style of training won’t make you reach your peak force faster, but it can help you develop higher levels of force. There’s a positive correlation between cross sectional area (muscle mass) and force production if you hypertrophy the right muscle fibers. This requires “muscle training.”
So through science and my own data with athletes I’ve developed a system of training that takes advantage of muscle and nerve training. Enlarging the muscles enables you to reach higher levels of force, while enhancing the nerve transmission helps you reach those higher levels of force faster.
I took the three ways science demonstrates that you can improve RFD and manipulated the parameters enough to grow your largest muscle fibers. This training will be known from here on as my NMD system, which stands for Neuro-Muscular Development.
I want to continue with the leg training example I gave in my previous post. Why the emphasis on the legs at first? Because that’s where most of your full body explosive power comes from.
The NMD system consists of three different types of training in a specific order for each workout. You’ll start with a sensorimotor (balance) exercise, followed by a ballistic or plyometric exercise, and finish up with a maximal strength exercise.
Balance Strength
For the legs, there are many ways to challenge your balance. For some, standing on one leg without shoes on a padded surface for 20-30 seconds is enough. Better conditioned athletes can stand on one leg and move their opposite leg around in a 180 degree motion from front to back with their eyes closed.
I have my athletes make the single leg balance more difficult by using a balance beam. They stand on one leg and perform a 1/4 squat in order to make the exercise more dynamic. Not so dynamic that it loses sight of the focus of developing balance, but dynamic enough to increase the challenge of the exercise.
Importantly, the balance portion of the NMD system isn’t supposed to make you tired. The purpose is to enhance sensory feedback between the muscles and spinal cord which sets you up for more powerful contractions in the ballistic exercise that follows.
Here’s a sample of me doing the single leg balance squat. You’ll start with three reps for the right, then three reps for the left. Next is two reps for each leg, followed by one rep with each leg.

The sequence in the video takes most people around 40 seconds to complete (20 seconds of total time under tension for each leg). Perform three sets of the sequence with one minute of rest between each.
Ballistic/Plyometric Strength
Ballistic and plyometric training are similar in the sense that they both use submaximal loads for fast, explosive muscle contractions. The difference, however, is that plyometric exercises always rely on the stretch-shortening cycle (SSC). For example, jumping up to a high box and then stepping off is a ballistic exercise. On the other hand, quickly jumping up and down with minimal ground contact time is a plyometric exercise.
I always start my athletes, or anyone who is new to the NMD system, with a ballistic exercise because it consists of lower impact forces and it’s less fatiguing. Remember, this part of the workout is followed by a maximal strength exercise with enough volume to hypertrophy the targeted muscles so fatigue must be managed. The goal of this part of the workout is to potentiate the nervous system, not fatigue it.
Here’s a video of me demonstrating the high box jump. Since I don’t immediately jump down and quickly reverse the movement, it’s a ballistic exercise.

You’ll notice in the video that the box I’m jumping on is padded. This helps reduce the impact forces even more. I know virtually none of you will have access to such a large, padded box, but don’t sweat it. I use it because I have access to it. Any elevated, solid surface will work.
Perform 3 reps in a row (step down between each rep), then rest for one minute. Perform 5 sets of 3 reps with one minute rest between each set.
Maximal Strength
This is the most straightforward part of the workout so it needs little explanation. You’ll use any lower body strength exercise and perform 3-8 sets of 3 reps. If the athlete is weak and needs plenty more maximal strength I’ll do 3 sets of 3 reps in order to keep the load as high as possible. If hypertrophy with a secondary emphasis on strength is the greater goal, I might do 8 sets.
For 3×3 I’ll use one exercise such as the front squat. Rest three minutes between each set. If hypertrophy is what I’m after I’ll use 8 sets and often alternate between two exercises such as the front squat and glute/ham raise (4 sets of each). Rest 90 seconds between each set when alternating between two different exercises.
Here are two examples of the NMD for Legs workout:
NMD Strength Emphasis
Single leg balance squat for 3/2/1 rep sequence for 3 sets with one minute rest between sets
High box jump for 5 sets of 3 reps with one minute rest between sets
Front squat for 3 sets of 3 reps with 3 minutes rest between sets

NMD Hypertrophy with Strength Emphasis
Single leg balance squat for 3/2/1 rep sequence for 3 sets with one minute rest between sets
High box jump for 5 sets of 3 reps with one minute rest between sets
Front squat/GHR pairing for 8 sets of 3 reps with 90 seconds rest between sets

This should give you enough information to experiment with my new NMD system. Start with the legs and we’ll build from there!
