Hi gang. Doing the pull-ups and chin-ups is causing me pain in my left elbow/forearm (almost like a sprain kind of feeling) and also a tight and uncomfortable pinch under my right armpit (and weirdly there is now a big bruise there--no idea what happened there). ANYWAY...in the name of not getting injured, I subbed in bent-over rows with dumbbells for all of the pull-ups and chin-ups. I always feel like a stud when I finish this one! Let's get it, friends!
