Cooling down and working on some combos couldn't finish the spin at the end lol the speedbag is the best way to burn the shoulders after your regular boxing routines from hitting the heavy bag and sparring, it has a lot of benefits especially timing and hand eye coordination and of course shoulder conditioning aside from that it's just tham fun hitting that thing
