This exercise specifically strengthens the gastrocnemius (your calf muscle) on the back of your lower leg by having you lift your heels up until you are standing on your tippy-toes.

Gallop
This is the scientific name for your calf muscle on the back of your lower leg, which gets a major workout during calf raises and bunny hops
