These exercises will do wonders for your leg lines! Understanding how to change your hip and knee position is key to this line-improving workout! I suggest you try all variations for sculpted, strong legs.
Captain's chair - You can keep the legs straight as shown, but when you first start, I suggest a tucked leg position. This exercise will improve your inverts dramatically.
Calf raise machine - Standing
Calf raises on squat machine - I prefer this machine over the standing calf raise because the weight can be too heavy on my shoulders.
