How the calculation works
A 5/3/1 calculator first creates or accepts a training max, then applies the percentages for the selected 5/3/1 version. The page must state whether the input is a true 1RM or training max and must name the template used. Percentages should never be applied to the wrong base.
- Training max = entered 1RM × selected training-max percentage, unless the user directly enters a training max.
- Working load = training max × set percentage.
- Show exact weight, rounded load, rounding direction, and actual percentage after rounding.
- Classic 5/3/1 and 5s PRO are different options. Do not merge their repetition instructions or AMRAP rules.
Continue with the Training Max Calculator. Create and project a conservative programming base.
For the next decision, read why 1RM and training max must stay separate.
Worked example
With a 180 kg estimated 1RM and an 85% training-max setting, the training max is 153 kg. A set at 75% is exactly 114.75 kg. If the selected increment is 2.5 kg, the interface must show whether it loads 115 kg and that 115 kg is 75.16% of the training max.
Continue with the 1RM Percentage Chart. Turn a max into exact and loadable percentage targets.
How to interpret the result
- The percentages in the table use the training max, not the true 1RM.
- Jim Wendler's public beginner guidance favors an intentionally conservative training max and says to err too light when uncertain.
- Deload timing, supplemental work, and progression differ across published 5/3/1 versions. The calculator should expose the selected version and avoid claiming one schedule is universal.
Limits and safety
- This tool is independent and is not affiliated with or endorsed by Jim Wendler or J M Fitness.
- The calculator performs arithmetic; it does not reproduce or replace a complete copyrighted training program.
- Pain, technique, recovery, assistance work, and exercise substitutions require individual judgment.

Inputs, outputs and result meaning
Calculates training max, week 1 top set, week 2 top set, and week 3 top set from max entered, max value, training max percentage, and template with visible method, validation, precision, and limitations.
Inputs
- Max entered
- Percentages are always applied to the training max. Available choices are True or estimated 1RM and Training max directly.
- Max value
- Supported units include kilograms (kg) and pounds (lb). The supported range is 0.01 through 2,000.
- Training max percentage
- Supported units include percent (%). The supported range is 50 through 100.
- Template
- Select one pattern; repetition instructions are not mixed. Available choices are Classic plus-set pattern and 5s PRO repetition pattern.
- Available load increment
- Use the smallest total-bar increment your equipment supports. Supported units include kilograms (kg) and pounds (lb). The supported range is 0.25 through 100.
- Rounding rule
- The exact value remains visible beside the loadable value. Available choices are Nearest increment, Round down, and Round up.
Outputs
- Training max
- This is the primary result. The visible value uses up to 2 decimal places according to the output rule.
- Week 1 top set
- The visible value uses up to 2 decimal places according to the output rule.
- Week 2 top set
- The visible value uses up to 2 decimal places according to the output rule.
- Week 3 top set
- The visible value uses up to 2 decimal places according to the output rule.
Full-precision calculation, one unit normalization, final display rounding. Keep the result label, unit, selected mode, and stated limitations together when sharing the answer.
Frequently asked questions
Is the training max the same as my 1RM
No. It is a deliberately reduced programming number.
Should I use 85 or 90 percent
Use the percentage specified by the program version you are following. Official public beginner guidance recommends a conservative choice.
Are all 5 3 1 sets AMRAP
No. Rep instructions differ by template, including 5s PRO and versions with plus sets.
How should weights be rounded
Use available plate increments and display exact and rounded values.
