Elastic Energy & Triple Extension Logic

Elastic Energy & Triple Extension Logic

Squat jumps and jump lunges train the stretch-shortening cycle in the quads, glutes, and calves — the same triple extension pattern that drives sprinting and jumping power. The dumbbell push press layers upper-body ballistic loading on top, teaching the body to transfer force from hips through shoulders under fatigue.

What Explosive Output Actually Costs You

What Explosive Output Actually Costs You

Repeated ground contact in burpees and jump lunges demands rapid eccentric braking, which accumulates neuromuscular fatigue faster than slow lifts. Full recovery between rounds isn't rest — it's the mechanism that preserves power output quality, because speed-strength degrades sharply when central nervous system fatigue compounds.

Rate of Force Development as the Target

Rate of Force Development as the Target

The warm-up progression from jumping jacks to high knees primes fast-twitch motor unit recruitment before the main work begins, not just tissue temperature. Dumbbell swings act as a hinge-pattern bridge between strength and power, and the plank anchors anterior core stiffness needed to transfer force without energy leaking at the midline. To personalize, increase dumbbell load on push press and sw
