The Simple, No-Equipment Workout You Can Do at Home

Lie on your back on the floor with your knees bent and your feet flat on the floor. Place your arms out to your sides at a 45-degree angle, your palms facing up. Now try to make your tummy as skinny as possible and hold it that way—this gives you a tight core—while breathing normally. That's the starting position [A]. Keeping your core tight, squeeze your glutes and raise your hips so your body forms a straight line from your shoulders to your knees. Pause for five seconds—squeezing your glutes tightly the entire time—then lower body back to the starting position [B]. Do 10 repetitions.
