Alright...managed to have a solid cardio session today without any joint issues. Not goint to get too excited yet, this happens every once and a while regardless of any joint suport I am taking. Just gotta wait and see if this continues and then it can be determined if it is ust coincidence or the AMSworking!
Also did not experience shoulder discomfort today, but I lifted very light due to muscle soreness I was experiencing. Too early to tell with this, also.
