[bbswisher92]

o.k for some odd reason my back foot can't come up or its hard for it to come up, any suggestions, my back tail will never hit the ground and i'm really getting frustrated and mad, and also is there any exercises i can do to strengthen my legs. thanks

its more of jumping, so i guess just jump and lift your knees, i heard biking helps cause its also a bit about thigh muscles.

just jump up and focus an lifting your knee
