Trap Bar Jump Squat
- Advanced
- Compound
- Timed hold
- Lower legs
- Upper legs
The Trap Bar Jump Squat is an explosive power movement that develops lower-body rate of force development and triple extension. It effectively targets the entire lower body while providing a more ergonomic, neutral grip that reduces spinal shear compared to traditional barbell variations.

Setup
- Step into the center of the trap bar with a hip-to-shoulder width stance.
- Hinge at the hips and bend your knees to reach the handles, maintaining a neutral spine and proud chest.
- Grip the handles firmly in the center to ensure the bar remains balanced during flight.
- Brace your core and pull your shoulder blades back to take the 'slack' out of the bar.
How to do it
- Inhale to create intra-abdominal pressure, then explosively drive through the mid-foot to jump vertically as high as possible.
- Exhale forcefully as you reach peak height, ensuring full extension of the hips, knees, and ankles (triple extension).
- Land softly on the balls of your feet, immediately sinking into a partial squat to absorb the impact through your muscles rather than joints.
- Reset your foot position and spinal alignment completely before initiating the next repetition.
Form checklist
- Keep your chest up and avoid rounding your lower back during the takeoff and landing.
- Ensure your knees track in line with your toes; do not let them cave inward.
- Maintain a tight grip on the bar throughout the entire flight phase to prevent it from tilting.
- Land with 'soft knees' to dissipate force safely.
Pro tips
- Focus on 'pushing the floor away' as fast as possible to maximize power output.
- For optimal power development, use a load between 20-30% of your Trap Bar Deadlift 1RM.
- Visualize your head touching the ceiling to encourage maximum vertical displacement.
Make it harder
- Perform 'non-reset' repetitions where you transition immediately from the landing into the next jump to improve eccentric-to-concentric transition speed.
- Incorporate a pause at the bottom of the squat before the jump to remove the stretch-shortening cycle and build pure starting strength.
