A Note About Safety:
1 Rep Max calculations are estimates of your maximum. You may or may not actually be able to lift your estimated maximum amount. Because it can be dangerous to attempt to lift your estimated maximum, always have a spotter with you. Seriously.

My 1 Rep Max will never bother you to request a rating or review. However, if you'd like to take the time to rate or review you can do so from the Settings screen and it would be very much appreciated.
