1. Lie on the ground with a bosu in front of you. Place your heels in the center of the bosu. Move your butt close to the bosu.
2. Place a resistance band across your hips and hold it down with your hands. Make sure it's tight enough to feel resistance.
3. Engage your abs, push through your heels, and raise your hips up, squeezing your glutes at the top of the move. Lower back down to the ground and repeat.
Do 15-20 reps - 3-4 sets. I like to superset this move with a heavier Glute exercise like a barbell squat. By the time you get to this move, your glutes will be on fire. This move also helps to activate the glutes.
