Do This 4-Minute No-Equipment Workout to Flatten Abs and Shape Your Booty

A little cardio, a little bodyweight strength training — this squat with a twist will keep the sweat coming while you work your buns and keep that core super tight.

• Come into a wide sumo squat; stand with your feet wide, toes pointing out. Bend your knees, lowering your hips deeply so your thighs are parallel with the floor. Make sure to keep your weight back on your heels.
• Punch to the left, then right.
• Return to standing and repeat. Perform the exercise for a full minute.
