Kick up your heels

If you are ready to kick up your heels for really sexy, shapely legs, try the decline single-leg cable curl. The cable’s movement is regulated by your leg. You’re forced to balance and control the movement.
Set the cable machine to a low setting. Then, position a decline bench far enough away from the low cable pulley on the weight stack so that the plates do not make contact at the bottom of the movement when you perform the exercise. Attach an ankle strap to the low cable and wrap it securely around your left ankle. Lie prone on the decline bench with your left leg extended. Place your right foot on the floor with your knee slightly bent.
Contract your hamstring and curl your leg up toward your glutes while keeping your thigh in contact with the bench. Further squeeze and pause at the top of the movement. Then, slowly control your leg back down to the starting position. Maintain a slight bend in your leg at the bottom of the rep and go immediately into the next repetition. Finish 12 to 16 reps with your left leg and then switch to your right.
