1RM math help (fig 1rm from 2 reps)

[attic]

hola, this is the second math+workout related question ive posted (so far, lol).
what im trying to figure out is: i lifted 237 twice (bench) and am curious what this would be as a 1rm. ive seen a couple different ways to figure this but i thought id ask here, thanks!

Step 1: Put more weight on the bar.
Step 2: Try to lift the weight.

Predicting One-rep Max


You're welcome.

PS I used to use this calc for every workout in order to accurately work out at say 70% 1RM max then 75, then 80. But a few months ago I just switched to xRM, such as 12 RM, 10 RM, and 8RM. It's much easier in my opinon and achieves the same progressive load effect.

PPS Why lift 2RM? Unless you're a powerlifter there is zero benefit except maybe stroking the ego . I don't waste my time with anything less than 6 RM.

Good for a general estimate, but muscle fiber genetics and the way in which an individual trains will cause quite a bit of variance.

True, but I would still put money on those predictions +/- 5 lbs.
