10 Ten-minute workout routines for your living room

The ab blaster workout is like a twist on an AMRAP (acronym for “as many rounds as possible”), but instead of performing a certain number of repetitions of each exercise, you’ll perform each exercise to exhaustion before moving on to the next exercise. The key here is that you’re always doing something — there’s no rest between exercises. Just keep moving until the 10 minutes is done.

The routine:

• Sit-ups (perform to exhaustion)
• Oblique twists (perform to exhaustion)
• Leg lifts (perform to exhaustion)
• Plank (perform to exhaustion)
• Continue repeating the series through

Sit on a mat with your knees bent, your heels on the floor and your toes pointing toward the ceiling. Hold your hands where they feel most comfortable — next to your ears, across your chest or even at your sides. Tighten your core and gradually roll yourself backward, vertebrae by vertebrae, until your shoulder blades touch the floor. Roll yourself back up in a similar manner. Continue to perform sit-ups to exhaustion.

Sit on a mat with your knees bent, your heels on the floor and your toes pointing toward the ceiling. Tighten your core and lean back slightly so your torso and knees make a “V” shape. Hold your hands in front of your belly button, your fingers touching. Keeping your hips and legs fixed in place, twist your torso to the right as far as you can, then reverse the movement and twist your torso to the left as far as you can. Continue twisting back and forth to exhaustion.

Lie flat on your back on a mat, your arms at your sides, your palms facing down and your legs straight. Tighten your core and press your lower back to the mat. Lift your heels slightly off the ground. Then, in a single movement, use your core to lift both legs all the way up until they form a 90 degree angle with your body. Keeping your core engaged and your back flat on the mat, carefully lower your legs back toward the floor, stopping just before your heels touch the ground. Continue the exercise to exhaustion.

Balance on your forearms and your toes, forming your body in a straight line from head to heels. Hold the position to exhaustion.
