Full description

You can estimate your 1RM based on the weight and reps you usually train with. In addition to the basic 1RM calculation based on the Brzycki formula, this calculator also supports more detailed and accurate 1RM estimates for squat, bench press, and deadlift using NSCA-based formulas. It also supports 1RM calculation for exercises that require bodyweight to be included, such as weighted pull-ups.

What's new

- Switched 1RM formula to Wathan with a 1RM-input exception. - Inputs persist through rotation and background. - Validation hints when inputs are missing or out of range. - Tap Done on the keyboard to calculate.
