Chest Tightness When Benching

Recently, whenever I bench press alot of weight (according to my own strength levels, very little according to others) my chest gets very tight. This happens while I am actually benching on the concentric part of the lift. For example I was benching 195 for 10 sets of 3. That is around 80-85% of my 1RM max of 235. As I got to the last 3 or 4 sets my chest started tightening. What is this from. And by the way right after the set my chest muscles go right back to normal.

breast cancer?

Your working your chest, thats why…
You also might want to try stretching your chest out.

I get the same thing. I just do close grip for a few weeks, and it goes away.

Try a sports bra. They’re elasticated…
