1RM (One Rep Max)
Definition
The maximum weight you can lift for one complete repetition with proper form.
Why It Matters
Your 1RM serves as the foundation for programming training loads. Most strength programs prescribe weights as percentages of 1RM (e.g., "work at 80% of 1RM").
How to Apply
Test 1RM after proper warm-up, using progressive jumps in weight with adequate rest (3-5 minutes). Alternatively, estimate 1RM using rep-max calculators from sets of 3-8 reps. Retest every 8-12 weeks to adjust training loads.
Common Mistakes & Fixes
- ⚠Testing 1RM when fatigued or unprepared
- ⚠Sacrificing form to hit a heavier number
- ⚠Testing 1RM too frequently (increases injury risk and fatigue)
- ⚠Not having spotters for maximal attempts on exercises like bench press
