Thanks for the helpful replies everyone.

It's been a few weeks since I posted my initial question and my shoulder is undoubtedly improving.

I have asked my physio why he had me doing the aggressive work outs in the gym and he said it's because the joint healed really tight from being in a sling for 6 weeks and we need to break down the scar tissue. We have also moved on to Olympic lifts such as cleans and dead lifts.

Lately, I've been going to physio twice a week so he can stretch my shoulder out. To be fair, it is an excruciating experience. He has me put my hands behind and above my head and pushes them far past my pain threshold. Last week we literally heard a loud rip inside the joint while he was performing this maneuver, which caused me to let out a rather choice word in the clinic. He said the ripping is completely normal and something that we are actually striving to achieve. Apparently I am in for a few more good rips in the coming weeks - lucky me.

He also explained that if we weren't to stretch it out, the joint would heal tight permanently and I may never regain a full range of motion. It's basically a battle against the scar tissue.

As far as the sprinting, I have been doing it at about 80% and haven't noticed any significant pain.

I will keep this thread updated with my progress. I would be interested in hearing any further insight into this situation as I haven't found as much information as I would have expected about the scar tissue from a labral repair.

Thanks again
