Don't lean forward, bro. You're just asking for a back injury by doing that. As Rugger said, you can tighten your abs in a controlled breath. Maybe that's something you can work on outside the gym as well, just holding your abs tight and breathing normally.
If none of that helps, you might just want to lighten up just a bit, if you're not having problems with lighter weight, start there and slowly work up to the weight and rep-range that this pressure begins to occur. I would then workout around that weight for awhile until you notice the pressure isn't there then slowly add weight so you're performing the exercise comfortably. |
