This static move is sometimes trickier than it sounds, but it’s worth the effort. As Jen Widerstrom, trainer on The Biggest Loser, told Shape, it’s the best holding position for working your core. Begin in a seated position with your legs out straight. Place your hands next to your thighs, and lift yourself up by pressing down into the floor. Because it’s impossible to nail the L-sit without fully engaging your abs, there’s no doubt you’ll feel the effects of this one. It’s a small move with big results.
Begin by standing with your feet hip-width apart. Bending at the knees, stick your butt out as though you’re about to sit in a chair. The aim is to get your thighs as parallel to the ground as possible, while keeping your knees over your ankles. The more you engage your core, the more effective the move will be for your entire body. Want a real challenge? Try jumping as you rise back to the top, then go right into another as you land.
3. Chest fly
To begin, lie on the floor with a dumbbell in each hand. Bend your knees so your feet are flat on the floor, and raise the dumbbells straight up over your head. Slowly lower your arms out toward the sides, and toward the ground. Don’t let your wrists touch the ground before returning to the starting position.
4. Close-grip push-up
Push-ups are pretty much a workout staple, so there’s no excuse not to master the move. Real simple suggests placing your hands directly under your shoulders. Make sure your elbows remain close to your sides as you lower yourself down toward the floor, then push straight back up. You’ll be engaging your core, while also toning your triceps.
