Resistance Band Glute Bridge

Lie faceup with knees bent, hip-width apart, feet flexed. Place the band across pelvis, pressing the ends into the floor by sides of hips. )Make it easier by adding more slack to the band, harder by pulling it tighter across hips).
 
Brace abs in tight, squeeze glutes, and quickly drive hips up into bridge.
 
Hold for 1 count, and then slowly lower for 3 counts to return to start.
