The Lazy Girl's Guide to Getting Strong

Use the single-leg bridge lifts to strengthen and tone your legs. This is a challenging move, so you'll feel the burn in your glutes and hamstrings. Here's how:

• Lie on your back and place your hands on the floor for stability as you bend one leg and lift the other leg off the ground.
• Then pressing your heel into the floor, lift your pelvis up, keeping your body in a stiff bridge position.
• Slowly lower your body to the floor and repeat. Switching legs, lift and lower 10 to 15 times.
