%1RM ↔ Repetitions Relationship Table
0% read · 2 min left
A reference table mapping the percentage of 1RM to the number of reps most people can complete — the bridge between estimated-1RM math, load prescription, and the RM continuum.
Detail
The number of reps achievable at a given %1RM is fairly consistent across people (it varies somewhat by exercise, training status, and muscle group). The NSCA load chart is the standard reference and underlies both estimated-1RM equations and intensity prescription (intensity, rm-continuum).
| % of 1RM | Approx. reps possible |
|---|---|
| 100% | 1 |
| 95% | 2 |
| 93% | 3 |
| 90% | 4 |
| 87% | 5 |
| 85% | 6 |
| 83% | 7 |
| 80% | 8 |
| 77% | 9 |
| 75% | 10 |
| 70% | 11 |
| 67% | 12 |
| 65% | 15 |
Training-goal bands (general consensus):
- Strength/power: ≥85% 1RM, ~1–6 reps.
- Hypertrophy: ~67–85% 1RM, ~6–12 reps.
- Muscular endurance: ≤67% 1RM, ~12+ reps.
Caveats: reps-at-%1RM are higher for large lower-body lifts than small isolation moves; trained lifters often grind more reps at a given % than novices; values past ~12 reps become unreliable for estimating 1RM.
Key facts
- Standard NSCA mapping: 100%=1, 95%=2, 90%=4, 85%=6, 80%=8, 75%=10, 70%=11, 67%=12 reps.
- Goal bands: strength/power ≥85% (1–6), hypertrophy 67–85% (6–12), endurance ≤67% (12+).
- Reps-per-% are higher for big lower-body lifts; vary with training status.
- Beyond ~12 reps the relationship gets unreliable for 1RM estimation.
