Place the desired level of CakeyBums resistance band around your thighs, 1 to 2 inches above your knees. Lay on your back with your right knee bent at a 45 degree angle, keeping your left leg straight in the air. With your core tight, press up through your right heel, raising your hips into the air and squeezing your glutes at the top. Slowly bring your hips back down to start while keeping your left leg in the air. Repeat 10 times on each leg to complete a set.
