The Bench Press Back Arch

Go into any gym or click onto any fitness/training page and there will be a debate that has been around since the first person laid on their back and pushed something heavy above their head.

I’m now picturing Fred Flintstone pressing a rock, but that’s silly.

The debate is whether or not we should arch the back during the bench press. And I mention this now because it has once again been brought up in conversation at my gym today. After somebody saw me arch my back during a bench press, they asked,”Are you supposed to arch your back?”

Knowing that the questioner was a football fan I came back with a football analogy. I replied,”If you are taking a corner kick should you knock it into the box or go short?”

The answer, of course, is that it depends on the circumstances. It depends on the stage of the game and the tactics that you or your coach wish to deploy. There’s no right or wrong, but the timing can be right or wrong. I’ll explain…

Arching the back is great for lifting heavier weights. It provides a more compound movement which recruits different muscle groups and helps create more power. And this is my reason for arching my back. In fact, I always bench press with my back arched because I don’t find it the best hypertrophy exercise, despite it’s many other qualities.

So, a chest press in order to promote pectoral hypertrophy would be to use a set of dumbbells at around 70% of your 1 rep max for 10-12 reps. Dumbbells allow a longer range of motion which can result in more muscle activation. The bar just can’t give you that sort of range, so a bench press with a bar without an arch, in my opinion, just gives you a ‘pump’. A few pics in the changing rooms for your Instagram look great but by tomorrow there will be nothing to show for it in real life.

I always use compound movements as my primary exercise and I often start with the bench press. Now in my 40’s, I have to look at ways of increasing my testosterone and compounds have the greatest success at doing this. I don’t bench press to ‘grow muscle’, just testosterone levels. However, once I pick up the dumbbells it’s all about weight management and hypertrophy.

Let the debate continue!
