Lie on back, knees bent, feet flat on a slippery surface (use sliders or towels).

Lift hips off ground into a glute bridge position.

Maintain bridge height. Slowly slide feet forward by straightening knees.

Extend legs as far as possible while keeping hips elevated and core engaged.

Engage hamstrings to pull feet back towards glutes, returning to starting bridge position.

Repeat for desired repetitions.
