Assume an L sit position on the floor, with straight legs extended in front of you.
Reach forward with straight arms, onto your fingertips, and drive them into the floor.
Difficulty is adjusted by how far you place your fingertips from your torso.
Appropriate placement should only allow for your heel to lift approximately 1 inch from the floor.
From this position perform raise one leg off the floor, engaging your quad and pointing your toes. Perform pulses, while keeping the leg elevated & maintaining tension throughout the set. Complete all reps on one leg before switching sides.
