"A weak core is often associated with weak glutes," Jaime told POPSUGAR. "This is a perfect exercise you can do anywhere to help strengthen the backside and, in turn, get a stronger core."
- On your mat, lie on your back with your knees bent and feet flat on the floor. Be sure to keep your feet underneath your knees, not in front. Plant your palms by each side, facing down.
- Press through your heels to raise your hips up to the ceiling, tensing your abs and squeezing your butt as you do. You should be making a long diagonal line with your body, from shoulders to knees.
- Hold for a few seconds, making sure your spine doesn't round and your hips don't sag. Keep your abs and butt muscles engaged.
- Lower down to the ground. This is one rep.
