Glute bridge with leg lift

Lie on your back with your knees bent and feet flat on the floor.
Reach your arms up towards the ceiling.
Press your feet into the floor lifting your hips off of the floor until your knees, hips, and shoulders are in a straight line.
Do not push so high that your lower back arches with this bridge movement.
Maintaining this position, extend the knee of one leg, pulling your toes towards your head.
Lower this leg back down until you are back in the bridge position and then extend the knee of the other leg, pulling your toes towards your head.
Repeat for the required number of repetitions and then relax down to the starting position.
