Never clench your jaw when working out. You're supposed to be working out the muscles of your arms or chest or legs or whatever, NOT the muscles in your face and head. I'm sure i recall reading some study that linked brain tumours to clenching muscles in the head.

Drop the weight amount if you can't handle it without clenching your jaw or do less reps.

If you want to train badass you have to go until you feel faint that is what I do. Tonight I felt like fainting after my final set of supersetting smith machine squats with leg press, I did 5 sets starting at 15,12,10,8,6.

Why would you train till you feel u are going to faint? Sounds unnecessary, dangerous (why block blood to the brain????!!!) and counter-productive.

It is not something I do deliberately, it is just a sign I am training with intensity.

I used to have sensitive teeth. My dentist recommended i used a sensitive toothpaste. One visit, he asked if i clenched or ground my teeth, maybe at night, since he could see some wear and tear. I said i was clenching my teeth in the gym and possibly at night (i was v stressed out).

He recommended i had a night guard made up. I thought about it and realised the problem was i was both lifting too much weight in the gym and being stressed at night.

So I simply lifted less weight (and had better results btw) and destressed at night before going to bed. No more sensitive teeth, and I can use a regular toothpaste at one-quarter the cost!!! :thumbup:
