Lay supine on the ground, heels of feet close to your glutes, feet flat on the floor slightly wider than hips with band wrapped around your lower thigh - just above knee height
Tuck your pelvis by drawing your belly button towards the floor, have arms laying down the side of your body
Using your glutes, drive your hips up until they create a diagonal line from knees to chest while maintaining tension on the band - this is your start position
Lower your hips to halfway - this is your end position
Return to start position and repeat desired number of reps
