hey y'all imma new to d M.A scene (2 months of karate) and i got introduced to it by my friend. well newayz i want to noe does M.A help wif muscle development? to make it more clearer: my friend is a young boy that nearly 15 and short but has a wide body (somewhat built) , though he may not b d tallest nor biggest guy at my skool, he can beat ne1 in an arm wrestle in our grade, (and our grade full of big built ppl), i mean he certainly doesnt look it but i mean he is reeeally strong. do u guys rekon dis is bcoz of his M.A experience dat made him so strong?
