I've had this debate in my mind for some time. When strength training, do we as humans reach a point where trying to get stronger will lead to smaller gains while the risk of injury increases significantly? For example, I could do a strength program like PTTP or SS and take my deadlift to 500-550lbs. That's definitely impressive and I think we can all agree that a person that can lift +500lbs is strong. But would trying to reach +600lbs be advisable for someone who does not compete? In other words, should we limit our strength in order to increase injury prevention? I realize that getting strong is a form of injury... but how strong is strong enough?
