47 year old male been in the gym since god created the heavens. between boxing and weights and everything between. still active in the gym at least 5 days a week. 12 years ago tore my right bicep on the heavy bag. refused to get it fixed, cuz one im stubborn and two was not in the mood to wait for a long recovery time of doing nothing....anyway big mistake i regret...regardless. the question finally...is it still worth it for me to do arm exercises at this point in the game? i mean for some reason its really bothering me the deformity and blah blah blah..but should i avoid due to the difference in arm sizes? i dunno..yes i know do what makes ya happy and stay active and all, but should i skip the arm workouts and just let them get their benefit from back and shoulder workouts??? no matter how hard i search i cannot find another online with my dilemma...any feedback would be great. thanx and god bless.
