Place the desired level of CakeyBums resistance band around your thighs, 1 to 2 inches above your knees. Lay on your back with your knees bent at a 45 degree angle. Keeping your core tight and your knees slightly pressed out, press up through your heels, raising your hips into the air. Focus on squeezing your glutes at the top. Slowly bring your hips back down to start. Repeat 10 times to complete a set.
