I injured myself years ago benching 290 flat. Then I injured myself close grip benching 215 close grip bench. So for about 2 years I've done dumbbell bench and hit 80 pound dumbbells. Then I switch to reverse bench. Well it's been a month and Im still at 135. I did dumbbell bench with 85 pound dumbbells after and got 4 out of the normal 6-8 reps I usually do for two sets. I'm going up on literally every other exercise but reverse bench. Any advice? Should I buy a swiss bar, or stick to dumbbells?
