Target muscles

The hip flexor of the suspended leg drives the knee. The quad and glute of the standing leg provide the base. The trunk braces against the asymmetric load.

How to perform

Setup

Place one foot in the strap. Lean forward in a staggered stance with hands on the floor.

Execution

Explosively drive the suspended knee forward toward the chest. Return it back. Maintain a powerful, controlled motion.

Common mistakes

  • Knee not coming up high enough.
  • Going too fast.
  • Letting the strap swing.
  • Asymmetric volume.
  • Soft trunk.

Progressions and regressions

Regress to standing high knees. To progress, work for time.

Programming notes
