One Rep Max Weight Lifting Definition

The One Rep Max Weight Lifting Calculator lets you instantly calculate your one rep max for the bench press, squat, curl, or any weight lifting exercise simply by entering in the amount of the weight and the number of repetitions that you have lifted it for.

The One Rep Max Calculator is very useful for estimating what your max squat, max bench press, max curl, etc. is without having to overly fatigue the muscles by actually attempting your one rep maximum with very heavy weight. Of course, the heavier of a weight you use then the more dangerous it can be to attempt to lift the weight without a spotter so estimating your one rep max also has the added bonus of being much more safe for anyone to use while measuring their one rep maximum lift without the use of a spotter (although using a spotter at all times is still recommended for ideal safety).
