Rep Range Guide
General training zones. Individual response varies.
| Goal | Reps | Percent of 1RM | Rest |
|---|---|---|---|
| Maximal strength | 1 – 5 | 85 – 100% | 3 – 5 min |
| Strength-size mix | 5 – 8 | 75 – 85% | 2 – 3 min |
| Hypertrophy | 8 – 12 | 65 – 80% | 1 – 2 min |
| Endurance | 15 – 25 | 50 – 65% | 30 – 60 s |
| Rule of Thumb | Train near failure | Progress weekly | Warm up properly |
