Lay on your back with knees bent and feet flat on the ground, assuming the bridge position. The body should be elevated and in a straight position throughout the duration of the move.
Extend the right leg so that it points forward, keeping the thighs at the same height. Then, raise the right leg so that it points towards the ceiling.
Slowly lower back to the starting position and repeat with the left leg.
For added resistance incorporate Body-Solid tools Ankle Weights, Reistance Tubes or Ankle Straps.
