OK, this is fixed. More than 10 reps (or less than 0 reps) will now give an error. See version 1.3 above.

This is a bug in the input validation. Only reps 1-10 should be allowed.

This is not accurate — I just put in that I could lift 75 LBS 30 times and my 1 rep max is 300. There is absolutely no way that is possible.

The units of the 1 rep max are in the same units that you enter the weight you lifted.

I'm considering getting an iPhone if there is an update at WWDC. If I get one, I would probably be interested in getting 1RM on there.

The different profiles is a cool idea.

Neither idea will probably be implemented soon (i.e. earlier than August), though.

Here's my wish list...

1) I'm curious if you could convert this widget into an iPhone app?

2) Also it would be really cool if there was an option to create 1rm profiles so you could plug in your own math based on wt. and reps.

I plan on getting an iPhone soon, and this would be ideal for taking to the gym..

Thanks

Bompa is excellent and without a doubt one of the best.

Brzycki published one that is used commonly. It looks like this:

Weight Ã· ( 1.0278 - ( 0.0278 Ã— Number of repetitions ) ), so it's a little different but maybe the predictions are very close as you said.

Thanks again.

I fitted a formula to the table given in Periodization Training for Sports by Tudor O. Bompa. I also checked this versus a few other sources and seems very close to what everyone else is using.

Where is the formula from?

thanks for listing what you used.

[...] I updated the 1RM Dashboard widget for Mac OS X and gave it a permanent home. The only change to the widget itself is a bit cleaner interface (check out the 1RM page for a screenshot). [...]
