I have not ruptured the bicep tendon, but it was severely aggravated at the end of last season. I ski with @Sailworks and as you may have seen in other threads, he is a big proponent of the power vest. I've seen him take 30-minute sets in that thing, it is amazing! Anyhow, he helped me diagnose my issue, and through some PT and lots of heat, stretch, and resistance - it feels better. Season in Upstate NY will start in the next few weeks.... so a question to others who have had this injury. How sudden did it happen? Was it stressed and building over time, or did it just explode all at once? I ask because mine seemed to accumulate, and never did rupture, just became very aggravated and I stopped skiing. I would hope when I get back out there I would get some warning if it was not happy, rather than a sudden blow-out.
