Exercise Overview

The snap down to vertical jump progresses force-absorption mechanics into explosive lower-extremity force production.

Clinical Purpose

The exercise challenges the athlete to rapidly transition from eccentric loading into concentric force production and introduces a more dynamic stretch-shortening-cycle demand.

Primary Muscles

Quadriceps, gluteals, hamstrings, gastrocnemius, and soleus.

How to Perform

Begin standing tall. Rapidly snap down into an athletic stance. Immediately reverse direction and jump vertically. Land the jump under control and reset.

Coaching Cues

Drop quickly.
Reverse direction immediately.
Push through the floor.
Jump vertically.
Land under control.

Common Errors

Excessive pause after the snap down.
Knee valgus.
Slow transition from landing to takeoff.
Poor trunk position.
Stiff final landing.

Common Clinical Uses

ACL rehabilitation, plyometric progression, lower-extremity power development, jump training, and return to sport.

Programming

3–5 sets of 3–6 repetitions.

Regression

Snap Down.

Progression

Countermovement Jump or Depth Jump.

Equipment Needed

Bodyweight.

Rehab Phase

Late.

PRO+ Clinical Pearl

The goal changes from simply absorbing force during the snap down to absorbing force and rapidly reproducing it during the jump.
