Tabletop may look easy (shown in the photo on the left), but once you hold it for a while, you'll feel your thighs, booty, and triceps burning. It's also a great exercise that will open your shoulders and chest. Here's a variation that will strengthen your core and increase flexibility in your lower back and hamstrings.

• Start off sitting on your bum, so your hands are planted eight inches behind you. Bend your knees and place your heels about a foot away from your hips. Make sure they are hips-width distance apart.
• Inhale and lift your hips off the ground so your torso is parallel with the floor and your arms are straight. Your hands should be directly underneath your shoulders and your ankles underneath your knees, so make small adjustments if you need to. Lower your head behind you to increase the stretch in your chest and neck.
• Hold for a complete breath, and then keeping your arms straight, exhale to lower your hips and straighten your legs, so your hips are hovering above the floor. Engage your abs and try keep your spine long as you balance on your heels and hands. After a complete breath, inhale and push yourself back into the first position.
• Do three sets of 12 to 15 reps, flowing from one to the other, pivoting on your hands and heels. To make this move more challenging, hold each position for longer.
