Unleashing the Beast: The Science of the Explosive Concentric Phase
STOP WAITING FOR LUCK. START TRAINING FOR POWER.
If you want to dominate on the field, you need more than just "hustle." You need elite-level sports science backed by a "Beast Mode" mentality. Before we dive into the deep end of explosive power, make sure you are signed up for our upcoming clinics and showcases at myfootballcamps.com, check out my personal training resources at coachschuman.com, and stay locked into everything happening with the squad at boardwalkbeastsfb.com.
The Payoff: Why We Train to Explode
Listen up. We’ve spent a lot of time talking about the "quiet" parts of athleticism, the eccentric phase where you lower the weight and store energy, and the isometric phase where you stabilize that energy. But today? Today we’re talking about the rock star. We’re talking about the concentric phase.
In the world of the Boardwalk Beasts, the concentric phase is the "overcoming phase." It’s when your muscles shorten to overcome a load. It’s the moment you explode out of your stance, the moment you high-point a ball, and the moment you drive a linebacker three yards into the backfield.
But here’s the cold, hard truth: the concentric phase is only as good as the energy you’ve managed to store. If you’ve learned to store energy like a coiled spring but don’t know how to release it, you’re just a heavy weight sitting on the floor. The concentric phase is the "payoff." It’s the synchronization of the entire triphasic muscle action. We are taking that absorbed energy and unifying it into one focused, dynamic movement.
If you can’t coordinate and unleash that power, all that heavy lifting you’ve been doing? It’s for nothing.
1. Intramuscular Coordination: Firing the Engine
When I’m in the weight room or on the field demonstrating an explosive squat or a vertical jump, I’m not just "moving." I’m trying to recruit every single fiber in my body to fire at the exact same millisecond. That is Intramuscular Coordination.
To maximize your Rate of Force Development (RFD), your brain has to send a lightning bolt to your muscles. There are three specific mechanisms we are training here:
- Motor Unit Recruitment: This is about numbers. We want to activate the maximum number of muscle fibers possible. You don't want 50% of your engine working; you want every cylinder firing.
- Rate Coding: This is the frequency. It’s about how fast your motor neurons can discharge signals. The higher the frequency, the more force you produce.
- Rate Coupling: This is the physical efficiency at the microscopic level, how fast those myosin heads can attach and pull.
When you train the concentric phase with maximum intent, meaning you are trying to move that bar as fast as humanly possible, you are teaching your nervous system to master these three things.
2. Intermuscular Coordination: Taking the Brakes Off
This is where most athletes get stuck. Your body has a natural "kill switch." When you try to move explosively, your antagonist muscles (the ones that do the opposite movement) naturally want to tighten up to protect your joints from tearing. It’s an overprotective "brake" system.
Think about it: if you're throwing a 90mph fastball, your biceps want to fire to make sure your elbow doesn't explode. But if they fire too early or too hard, they slow down your arm.
Intermuscular Coordination is training your nervous system to inhibit that antagonist response. We are teaching the "brakes" to stay off until the very last second. Elite Boardwalk Beasts athletes move faster not just because their "gas pedal" is stronger, but because they know how to let go of the brakes. We want zero resistance from the rest of your body when you decide to go into Beast Mode.
3. Reactive Ability: Organizing the Chaos
When you snap into a concentric contraction, there is a lot of "physiological chaos" happening inside your body. You have the stretch reflex firing, the muscle contracting, and the stretch-shortening cycle (SSC) trying to dump all that stored energy.
We call the ability to organize this chaos Reactive Ability.
The Well-Trained Athlete:
When a Beast is well-trained, the transition from storing energy to releasing it is fluid and seamless. The concentric contraction builds intramuscular tension instantly. This creates an additive effect with the stretch reflex. Because it’s so fast, very little energy is lost to the environment. You are transferring 95% of that stored energy directly into the movement. That’s how you get a 40-inch vertical or a sub-4.5 forty.
The Poorly-Trained Athlete:
If your concentric mechanism is slow, there’s a lag time. During that delay, the energy you stored in your tendons and connective tissue doesn't just wait around. It dissipates as heat. You’re literally "leaking" power. This creates a "dip" in your force production, and you’ll never reach your maximum potential RFD. You’re working twice as hard for half the result.

How to Train the Explosion
You don't get this kind of power by just going through the motions. You need to train with Intent.
- Compensatory Acceleration: Every time you lift, whether it's 50% of your max or 90%, you move the concentric phase with the intent of breaking the ceiling.
- Plyometrics: We use these to bridge the gap between the weight room and the field. It forces that reactive ability to sharpen up.
- Specific Skill Work: This is why we do our QB/WR Elite Series. You need to take that raw power and apply it to your specific position.
Don't Let Your Power Go to Waste
The difference between a starter and a benchwarmer, between a D1 prospect and a "good high school player," is often just this: the ability to unleash. You can have all the "potential" in the world, but if you can't coordinate your nervous system to unleash that power in the concentric phase, that potential is just heat leaving your body.
We don't train to be warm. We train to be explosive.
If you're ready to stop leaking energy and start dominating, I want to see you at our next event. We’ll get under the hood, fix your mechanics, and turn you into a high-performance machine.
