How to use this tool

  1. Enter your 1rm in the fields above.
  2. Results update instantly as you type — or click Calculate.
  3. Read your 50% (warm-up) and the full breakdown beneath it.

Enter your one-rep max (1RM) to generate a full percentage table for programming training loads. Common strength programs use 70–85% for hypertrophy sets and 90–95% for heavy strength work.

Formula

Load at X% = 1RM × (X ÷ 100)

Applied for X ∈ {50, 60, 70, 75, 80, 85, 90, 95, 100}.

How it works

The calculator multiplies your one-rep maximum by a fixed percentage to give the corresponding training load for each intensity zone commonly used in strength and hypertrophy programming.

Percentages are applied directly without rounding, so you can choose how precisely to load the bar. The table is only as accurate as your entered 1RM; regularly re-test or use an estimated 1RM from a rep-max calculator for best results.

Worked example

Worked example

  1. 1RM = 120 kg.
  2. 50% load: 120 × 0.50 = 60 kg.
  3. 80% load: 120 × 0.80 = 96 kg.
  4. 90% load: 120 × 0.90 = 108 kg.
  5. 100% load: 120 × 1.00 = 120 kg.

50% = 60 kg | 60% = 72 kg | 70% = 84 kg | 75% = 90 kg | 80% = 96 kg | 85% = 102 kg | 90% = 108 kg | 95% = 114 kg | 100% = 120 kg

Key terms

1RM (one-rep max)
The maximum weight you can lift for exactly one complete repetition with good technique.
Training intensity
The percentage of 1RM used in a set; higher percentages recruit more muscle fibres and develop maximal strength.
Intensity zone
A percentage range associated with a specific training goal, e.g. 70–85% for hypertrophy, 85–95%+ for maximal strength.
Progressive overload
Gradually increasing training load over time to drive continued strength adaptation.
Rep-max continuum
The inverse relationship between load (% 1RM) and the number of repetitions possible; e.g. ~80% typically allows ~8 reps.

Frequently asked questions

What percentage should I train at?
It depends on the goal: 50–65% for speed/technique work, 65–75% for volume/hypertrophy, 75–85% for strength, 85–95% for peaking, and 95–100% for competition attempts.
How do I find my 1RM?
Either test it directly (with a spotter) or estimate it from a multi-rep set using the Epley formula: 1RM = weight × (1 + reps / 30).
