Im making the post for a friend. Last year he had spinal sergio to remove a tumor. and after all the bs was over pretty much all the muscles in his left leg were gone. he is still havin trouble gettin his muscle back. Its like from his toes,calf , all the way up to his hip. He isnt trying to get buff or anything just tryin to get the muscle back so he doesnt have to were a leg brace and what not. Calf raises are pretty much outta the question for know because he cant eve stand on his tippy toes.. Any exercise for him?
