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. If it detects a new personal record for a specific exercise, it celebrates. The record set will be marked with a yellow cup.

Remember there are also body weight exercises where you do not enter a weight. In this case there is no One Rep Maximum, because the 1RM value is a weight value. Therefore, for body weight exercises, personal records are based on the number of repetitions. A body weight exercise record is marked by a white cup.

Awards

If you break a record, the new set gets the cup marking, and the old set loses it. But don't be sad, the old set gets an award instead, marked with a badge. This is very useful for analyzing previous achievements, because you can easily see phases where you made progress and where it stagnates.
