Lie on your back, start with your hips flexed, legs straight, and pointed to the sky.
Engage your core, by pressing your lower back into the floor.
Slowly begin to lower your legs, while maintain this tension. Squeezing the glutes, legs engaged.
Exhale on the descent.
Stop before you lose tension, don’t allow your back to arch, or legs to drop, keep the core engaged throughout the movement.
Inhale as you raise your legs.
Repeat for reps.
