Arched back is an issue when squatting or dead lifting or other movements with significant vertical load on the back. Not the case with bench pressing. Bouncing out of a squat is also perfectly safe.

I think it's worth saying that they are advanced techniques that have a decent potential for injury. Inexperienced people should avoid them entirely. Even experienced lifters should have someone trained watching them as a spotter. Remember, your back needs to be arched for the entire set. Anything else is likely to cause injury.

I very much disagree about bouncing out of a squat. Maybe while warming up or with light weight it's ok, but with heavy weights, the safest technique is a steady and smooth motion while staring at the top of the rack to force a straight back.

Oh the staring bit is a good idea. I didn't know that.

Yep! It's a trick my coach taught me in highschool, it works great and keeps it simple
