One Rep Max 1rm Calculator
A precise tool.
What is the One Rep Max 1rm Calculator & How does it work?
The One Rep Max (1RM) is the maximum amount of weight that a person can lift for one repetition in a single effort. It’s a crucial metric in strength training, helping to assess and improve an individual’s strength levels.
1RM = frac{W times (1 + 0.025 times R)}{1}
W = weight lifted, R = number of repetitions performed
This formula is based on the Brzycki equation, which provides a good estimate of 1RM. It’s important to note that this calculation assumes proper form and technique during the lift.
