Core Exercise - Foot Lift

Core stability foot lift exercise.

Lie flat on your back with your knees and hips bent up so there is a small space between the hollow of your back and the floor.
Inhale to prepare and while exhaling engage your core.
Inhale again and as you exhale raise one foot a couple of inches off the floor, keeping the knee bent.
Inhale and bring your foot back to the floor.
Repeat this on alternate legs.
