Calculators

Estimate your one-rep max from a bench press set and calculate the predicted number of bench press reps you can perform at a target weight using common strength formulas.

Estimate your one-rep max bench press using training weight, repetitions, body weight, experience level, and pause style. This calculator uses common strength-training logic to project a bench press max from a working set.

Estimate your bench press training max using your best recent lift, reps performed, fatigue adjustment, and training max percentage. Useful for 5/3/1-style programming and conservative strength planning.

Calculate the bench press working weight based on your one-rep max, target training percentage, reps, and unit selection. Useful for programming strength sets and estimating adjusted load for rep-based training.

Estimate your bench press one rep max using the Epley formula based on the weight lifted, reps completed, bodyweight, and training experience.

Estimate your bench press one-rep max (1RM) using training weight, repetitions, bodyweight, bench pause style, and experience level. The formula uses the Epley method with small adjustment factors for paused benching, touch-and-go style, and lifting experience.

Estimate your one-rep max bench press using your lifted weight, reps completed, body weight, and training experience. The calculation uses a standard rep-max formula with a small experience-based adjustment.

Estimate your one-rep max on the bench press using the weight lifted, reps completed, body weight, training experience, and technique quality. This calculator uses a rep-based one-rep max estimate and applies small realistic adjustments for experience, body weight, and lift quality.

Estimate your one-rep max (1RM) for the bench press using the weight lifted, repetitions completed, bodyweight, and training experience. The calculation uses the Epley formula with a small experience-based adjustment and a bodyweight strength factor for a more realistic estimate.

Calculate a vehicle’s power-to-weight ratio using engine power, weight, power unit, and weight unit. The result is shown as horsepower per metric ton, a common benchmark for comparing performance across cars, motorcycles, and other vehicles.

Calculate the training weight based on your one-rep max (1RM), desired percentage, rep target adjustment, and available equipment increment.

Calculate strength-to-weight ratio by dividing the weight lifted by body weight, with optional unit conversion for body weight and lifted weight.

Calculate a stock’s relative strength versus a benchmark by comparing percentage price performance over a selected period. A value above 100 indicates outperformance, while a value below 100 indicates underperformance.

Estimate overall strength level based on body weight, one-rep max performance, training experience, and sex. The calculator produces a composite strength score that can be used to compare relative lifting level.

Calculate what percentage of your one-rep max a lifted weight represents based on the weight used and your estimated or known 1RM.

Estimate how many repetitions you can perform at a given weight based on your one-rep max, exercise type, and training experience.

Estimate your one-rep max and equivalent target weight from the weight you lifted, the number of reps completed, the target reps, and the prediction formula selected.

Calculate the target weight to use for a lift based on your training max and chosen percentage, with optional rounding to the nearest practical plate increment.

Estimate your training max based on the weight lifted, reps completed, exercise type, and desired training max percentage. This calculator uses a common one-rep max estimation approach and then applies a percentage to set a practical training max for programming.

Calculate the estimated training weight based on your one rep max, target percentage, available plate increment, and unit system. Useful for strength programming, percentage-based lifting, and rounding working sets to the nearest loadable weight.

Estimate your one-repetition maximum (1RM) strength based on the weight lifted, repetitions completed, body weight, lift type, and training experience.

Estimate an overall strength score using one-rep max, body weight, training experience, and lift quality factors.

Estimate your one-rep max (1RM) for a weightlifting exercise based on the weight lifted, repetitions completed, exercise type, and training experience.

Estimate the maximum number of repetitions you can perform at a given weight based on your one-rep max, bodyweight assistance or loading, and exercise difficulty.

Estimate your one-repetition maximum (1RM) based on the weight lifted, number of reps completed, exercise type, and training experience using a weighted version of common rep max formulas.

Estimate your one-repetition maximum (1RM) from the weight lifted, repetitions completed, exercise type, and training experience using a practical strength formula with small adjustments for exercise complexity and lifter experience.

Estimate your one-repetition maximum based on the weight lifted, repetitions completed, exercise type, and training experience.

Estimate your one-repetition maximum (1RM) using the Epley formula based on the weight lifted and the number of repetitions completed.

Estimate VO2 max using a 1.5 mile run test with age and sex adjustment factors. Enter your age, sex, body weight, run time, and average heart rate during the test to estimate aerobic fitness in mL/kg/min.

Estimate an appropriate deload working weight based on your normal training weight, target deload intensity, planned volume reduction, and training experience.
