I’ve never had anything like this happen, so I’m not sure if maybe I just pulled a muscle or maybe something worse. I did my first set of pull ups and getting higher in range I heard/felt a crunching/popping in the back of my arm where the tricep ties into the back. It finally felt like a Charlie horse so I dropped off the pull up bar and rested a minute. It felt just a bit awkward so I went to do the next set and as soon as I tried to pull, it had the Charlie horse feeling like I’d been punched in the back of the arm. Immediately stopped and got on the treadmill to at least do something. Came home, took an anti inflammatory, slapped on a salon pas and logged onto Getbig ASAP. Any thoughts fellow bro-scientists?
