Knee Tuck Jump

What it is

This dynamic bodyweight movement develops explosive power and agility. You'll quickly dip into a quarter squat, then jump high, tucking your knees towards your chest. It primarily works your hamstrings, with strong contributions from your quadriceps, glutes, and calf muscles.

Technique tips

• Dip quickly into a quarter squat before exploding into your jump.
• Drive your knees high towards your chest at the peak.
• Keep your hands steady at chest height as a target.
• Absorb your landing softly by bending your knees.
• Maintain a stable upper body throughout the movement.

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
