No Need to Ever Do Lunges Again With These Thigh-Sculpting Moves

You can work the backs of your legs without standing. Just be sure to not arch your back to raise your leg — that's cheating.

• Start on all fours, with your hands directly under your shoulders and your knees directly under your hips.
• Slowly pulse your flexed foot toward the ceiling by squeezing your glutes. Your back should remain perfectly still in a neutral spine. The motion should be small and controlled with the muscle doing the work and not momentum.

Variations
— Rotate your raised knee outward slightly and make small pulses by raising your knee to work your glutes from another angle.
— Place a lightweight dumbbell at the crook of your raised knee to make the move harder.
