One Rep Maximum

Your one rep max is a calculated approximation of the most weight you can lift for exactly one repetition. It provides a way to compare sets that may have different weights and repetitions with a single number that can be easily graphed over time. To understand the problem, consider a set of 200 lbs x 10 reps, and a set of 200 x 9 reps. Obviously the former is the better set. But what about a set of 210 x 9? Now which is better? Well, the 1RM of 200 x 10 is 267, meaning that if you can lift 200 lbs 10 times, then you can lift 267 lbs once, whereas the 1RM of 210 x 9 is 270. Therefore, 210 x 9 is a better set than 200 x 10.

Personal Records

GymACE calculates the One Rep Maximum for each set. When you achieve a new personal record for a particular exercise, you celebrate. The record is marked with a yellow cup.

Keep in mind that there are also bodyweight exercises where you don't enter a weight. In this case, there is no One Rep Maximum because the 1RM value is a weight value. In bodyweight exercises without a registered weight, a personal record is measured by the number of repetitions. Such a record is marked by a white cup.

Badges

If you break a record, the new set gets the trophy marker and the old set loses it. The set with the old record will be marked with a badge. This is very useful for analyzing past successes, as you can easily see in which phases you have made progress and in which phases you stagnate.
