The seated box jump eliminates the stretch-shortening cycle by starting each rep from a dead stop on a box, forcing you to generate explosive power purely from concentric muscle action. Unlike regular box jumps where you use momentum from the countermovement, seated jumps require raw starting strength. This makes them one of the best exercises for developing explosive power.
When to use it
Use for developing explosive power.
Who it's for
Athletes wanting explosive strength.
Pause completely on the box before each rep—any bounce or rock defeats the purpose. Generate maximum intent before exploding upward. The jump should feel significantly harder than a normal box jump because you cannot use the stretch reflex.

Land softly with bent knees.
Step down and reset.
Eliminates the stretch reflex.
Pure concentric power.
Great for explosive strength.
Program seated box jumps during power phases for athletes who need starting strength, or as a plyometric that teaches maximum force production. Use them early in workouts when fresh since explosive quality matters more than volume. They pair well with heavy strength work as part of a contrast training protocol.
Using momentum from a bounce.
Bouncing or using momentum during the Seated Box Jump makes the movement harder to control and can shift work away from your Quadriceps. Use a load you can move smoothly through the intended range.
Landing with straight legs.
Squatting patterns like the Seated Box Jump coordinate the hips, knees, and feet. Keep those positions consistent and use a range you can control while your Quadriceps carries the intended load.
Box too high - this is a common issue that reduces exercise effectiveness.
Squatting patterns like the Seated Box Jump coordinate the hips, knees, and feet. Keep those positions consistent and use a range you can control while your Quadriceps carries the intended load.
Athletes wanting explosive strength.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3-4 sets of 4-6 reps. Rest 90s-2min.
