Bench Press Calculator: Calculate Your 1 REP MAX (1RM)

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 Calculator

Weight:

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.

Nah that's not bad, I'm 15 and started lifting in August, my bench max was maybe 115 then, by October it was 165, and now I can rep like 135 10-11 times and it's estimated at 180. Just keep going hard at it and you will see results.

Im 15 years old and im in weight training and my bench max is 145lb. and im having trouble figureing out my squat max because most websites only go to 20 reps well i did 225lb. for 30 reps how to i figure out my max for squat?

Make sure you are doing a squat till parallel. So hamstrings should be flush with ground. I was repping 225 for 30 on a bench, i could do 350. But when id punch 20 reps of 225 it said i should 1rm 400. What I recommend to be safe is up weight from 225 to 275. Than see how many reps you get. The calculator is only a guess. So dont try 405 until you rep closer to that weight

If you're doing your bench press the way you're doing your squat, then you're not doing it correctly. You should go all the way down and touch your chest on bench and then all the way back up and lock out and contract. If you're benching 225 for 30 reps correctly your bench should be well over 400(I'd say around 440-450)! Also, M&S's bench press calculator does not say you should be getting 400 X 1 if you can bench 225 for 20. No, it calculates to 364. On a good strong day I can get 225 for 21 FULL reps and that is right on target because my max is 365. Don't sacrifice form just so you can "get" more weight. Get the full benefit when you lift!

Just got a bench like 3 months ago maybe
Could barely do 155 for 3 on the bench.
I do 3 sets of 155 the reps increase every work out
But I'm trying to limit to a ten rep set.
I Max out too much because I just feel stronger and able to so I tend to Max out about every week and a half
A month ago my 1rm was175 now I'm at 190.
My current goal is 205.
