Calculators

Calculates the weight for each set in the 5/3/1 strength training program based on your training max.

Calculates a Wilks score, a coefficient used in powerlifting to compare the strength of lifters of different body weights and genders.

Helps structure a bench press workout using ascending and descending weight/rep schemes.

Estimates your One-Rep Max (1RM) for the bench press based on the weight lifted and the number of repetitions performed.

Estimates the maximum weight a person can lift for a single repetition (1RM) based on the weight lifted and the number of repetitions performed.

Compares athletic performance (e.g., race time) against world records for age and gender. This calculator provides an age-graded percentage, indicating the quality of the performance relative to the world record for that age and gender.

Estimates VO2 max specifically tailored for runners, often using race times.

Estimates maximal oxygen uptake (VO2 max), a key indicator of aerobic fitness, using test results or formulas.

Calculates cycling power training zones based on your Functional Threshold Power (FTP).

Estimates cycling power output (watts) based on speed, gradient, weight, and other factors.
