Persistence is key
I’m sure you’ve heard people in the gym tell you to never do the same thing every time you go into the gym – and there’s certainly some truth in that. However, if you’re into power lifting and trying to get the biggest squat, bench, and deadlift numbers possible, then you may want to reconsider.
Think of the big three lifts containing two parts: Strength and proficiency. I agree that a strong bench will not come from just doing bench and no other accessory lifts such as shoulders or hitting triceps. However, one cannot become a bench expert if they do not perform the motion as often as possible. You can benefit by doing flat bench every chest workout by switching up the weight used (Think of speed days here), benching with bands, or doing board work. The idea behind this is that you’re still doing the same movements so you can become an EXPERT getting that bar to travel in just the right path to get you that 375 bench at 181 bodyweight.
Does this mean that on your chest days you should only do flat bench? No, you can do other chest lifts as well, but remember… Don’t over do it!
