4. Bridge With Leg Lift
Lifting your leg as you do this bridge exercise helps to isolate your butt muscle on the leg that’s still touching the floor.
Lie face-up with legs bent, feet on the floor and arms at your sides. Tighten your abs, lifting your hips off the floor. Next, raise your right foot off the floor, straightening your leg in the air and keeping both hips level with each other. Hold for three seconds; return foot and hips to floor. Repeat, alternating the leg lift on each side.
Tip: To avoid over-arching your back, keep abs tight throughout the exercise.
