Lie on your back on the floor and rest your arms straight by your sides. Then, lift both legs up about 3 inches off the floor and keep them straight. Now, do a scissor motion with your legs by alternating them up and down so that they pass each other. Repeat for the desired number of reps.

Commence this exercise by lying flat on your back, your hands at your side, and your feet slightly off the ground. Then lift one leg so it is vertical, keeping both legs straight. Now lift your other leg vertically while lowering your first leg back close to the ground. Continue to alternate each leg up and down every rep for a set of 15-30 reps.

Set up in your normal hanging leg raise position. Establish full body tension, raising one leg to approximately 90 degrees while keeping the other locked out in its original position. Lower your leg back to the starting position and raise the opposite leg to 90 degrees. Repeat while alternating working sides to complete your set.

The alternating lying leg raise is a more accessible variation of more intense hip flexor exercises like the hanging leg raise, and like the dead bug, the purpose is to both strengthen the hip flexors independently for balance, and the ability to stabilize the pelvis against unwanted movement.
