Late to the party, super sorry to hear about the bum wheel! Hammer some progressive overload...free standing HSPU's on paralettes...wearing a 30lb vest?! I arm chins? I think we will see some growth with that. If the fat gain is an issue just keep a tight reign in the nutrition. Track EXACTLY what you are eating to keep most gains flowing into Los Musculos.
Keep us posted you big stud!
