The Muscle & Strength bench press calculator can be used to work out your approximate 1 REP MAX bench press. These figures are not 100% accurate, but it serves as a good guide!

Bench Press (1RM) Calculator Instructions

This bench press calculator can be used to work out your approximate 1 REP MAX bench press. The way this bench calculator works is it takes the amount of weight you can bench for a certain number of reps and uses a formula to calculate your approximate 1 REP MAX. Obviously, these figures are not 100% accurate.

To use the bench press calculator simply enter the weight in the first box provided and select the number of reps from the drop down box. For example, if I benched 225lbs for 10 reps I would enter 225 and select 10 reps. The bench press calculator works in both pounds and kilograms.

I've been eating a carnivore diet of meat, eggs, fish, bacon,and lots of fat. My bench has shot up dramatically since I started eating this way. Carbs and sugars will destroy your bench. Six months ago I could barely work out with 185 on the bench. Now I'm putting 225 up for 10 reps.

Tendinitis in left shoulder. At 71 I’m just glad to be here. Enjoy lifting for years. Hope to get back to benching 300 one more time. Have fun with your time working out. Mix it up, do different things and have some good music blasting
