I'd like to refute the claim that going down to parallel is safer than going down below parallel.
Assuming you're doing a squat, and stop at parallel, you need to change the momentum of your motion from downwards to upwards. When you're at parallel, your knees are acting as a pivot point and thus feel the strongest component of that inertial change. If you go below parallel, the inertial change is felt mostly on your ass. Your ass, being muscle and not joints, can inherently handle the force more safely.
Powerlifters use knee wraps because undisputably you are the weakest down below parallel and the wraps serve to put some tension back into the system that 'snaps' you back up. Safety is an issue with wraps too, but a bad wrap job can be worse than no wraps at all, especially because you can store a hell of a lot of potential energy in those wraps and if they're done unevenly or poorly, you'll end up in lots of pain. I would say that a novice with wraps is going to be in more danger than a novice going below parallel with a managable weight. Plus the wraps cut off your circulation below too, that's why they go on right before a set and off right after that set. That's why their a PITA - rolling up your wraps correctly really, really wears out your hands.
I'm sure any powerlifter here can collaborate what I say.
All correct.
At parallel your knees are taking
the greatest load. You want to spend as little time their as possible. If you go all the way down you by past this. You spend less time at parallel.
I'd like to add I hardly see people go to parallel or anywhere near it.
PL do a different squat. They for competition PL have the bar lower on their backs as it shortens the lever in a PL squat. They "sit" back in squat and not down. They go to parallel. They where knee wraps because it helps them lift more simply put. The elastic affect of the knee wraps helps them. Some guys will also wear a
squat suit to lift more. Yes they are strong but a squat suit will add some poundage to your life. NOT important to a typical gym guy.
I say go to rock bottom. Go all the way down.
Doing 100's of push ups is TOUGH on your elbows. Doing pull ups is VERY tough on your elbows. Imagine about 90% of your weight on your elbows (some on your back but most of it on your elbows). That is A LOT of weight there.
Bench Pressing is also very tough on your elbows and shoulders.
Playing a lot of BBall is VERY tough on your ankles. Running miles and miles is very tough on your knees.
Squats are safe if you do it properly. Slowly down and up fast. DON'T CRASH to the bottom and bounce up. You will knacker your knees out eventually this way if you have no muscle to take the blows but then IT IS NOT SAFE.
