What muscles are used in skipping rope?

Wrong. For one, your quad muscles are your rectus femoris, vastus medialis, vastus intermedias and vastus lateralis. Biceps femoris and semimembranosis are part of your hamstring msucles. Secondly, calf muscles include the gastrocnemius and the soleus, while the tibialis anterior is part of the front compartment of the lower leg, not the calf.

And to make everyting straigght, all major muscle groups are worked out during a skipping exercise. Abdominals to stabiliase your body, legs for the jumping, biceps and lats and traps for the propelling of the rope.

Hope that helps
