How the calculation works
Multiply a tested or estimated one rep max by the percentage required by your program. A 180 kg 1RM at 90% gives a 162 kg training max. If the bar loads in 2.5 kg steps, the result must show the exact value and the selected rounded value separately.
- Training max = one rep max × selected percentage / 100.
- Keep the source max labeled as tested or estimated.
- Round once at the final load stage and disclose the increment and direction.
- If a program supplies its own training-max rule, that rule takes priority over a generic preset.
Continue with the One-Rep Max Calculator. Estimate 1RM from a technically consistent submaximal set.
For the next decision, read 1RM versus training max.
Worked example
A lifter enters an estimated 137.5 kg 1RM and selects 85%. The exact training max is 116.875 kg. With 2.5 kg bar increments, nearest rounding gives 117.5 kg; rounding down gives 115 kg. The tool should allow or disclose the rule rather than hiding the difference.

How to interpret the result
- A training max is a programming base. It is not a claim that strength has decreased.
- There is no universal training-max percentage. The correct setting comes from the program or coach.
- When the source 1RM is estimated, all derived values inherit that uncertainty.
Limits and safety
- Do not automatically raise a training max because an individual session feels easy.
- Do not use a generic 90% setting when a named program specifies another value.
- The calculation does not account for fatigue, injury, technique, or lift-specific readiness.

Inputs, outputs and result meaning
Calculates loadable training max, exact training max, rounding difference, and final projected TM from true or estimated 1RM, training max percentage, available load increment, and rounding rule with visible method, validation, precision, and limitations.
Inputs
- True or estimated 1RM
- 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.
- 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.
- Cycles to project
- Supported units include cycles. The supported range is 1 through 12.
- Increase per cycle
- Supported units include kilograms (kg) and pounds (lb). The supported range is 0 through 50.
Outputs
- Loadable training max
- This is the primary result. The visible value uses up to 2 decimal places according to the output rule.
- Exact training max
- The visible value uses up to 4 decimal places according to the output rule.
- Rounding difference
- The visible value uses up to 4 decimal places according to the output rule.
- Final projected TM
- 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
What is a training max
A reduced number used to calculate programmed work sets.
Is 90 percent always correct
No. Use the percentage required by the program.
Can I use an estimated 1RM
Yes, with an estimate label and conservative rounding.
Why round down
Some programs prefer conservative loading. The tool should display the exact value so the rounding choice is transparent.
