Percent of 1RM Training Chart: Loads, Reps, and Intensity Zones
October 21, 2026
Once you know or estimate your one-rep max, percentages turn it into training loads. As a rough guide, you can lift about 95% of your max for 2 reps, 90% for 4, 85% for 6, 80% for 8, 75% for 10, and 70% for 12. For someone with a 100 kg max, those loads are 95, 90, 85, 80, 75, and 70 kg.

These rep numbers are averages taken from commonly used strength training tables. Individual results vary by exercise: people usually manage more reps at a given percentage on leg presses than on bench presses, and fewer on the last set.
| % of 1RM | Typical max reps | Load for a 100 kg 1RM | Main focus |
|---|---|---|---|
| 95% | 2 | 95 kg | Maximal strength |
| 90% | 4 | 90 kg | Strength |
| 85% | 6 | 85 kg | Strength |
| 80% | 8 | 80 kg | Strength and size |
| 75% | 10 | 75 kg | Size |
| 70% | 12 | 70 kg | Size and endurance |
| 60% | 15+ | 60 kg | Endurance, technique |
Using Percentages in a Program
A simple strength block might use 4 sets of 5 at 80% for four weeks, then 5 sets of 3 at 87.5%, then a test. Hypertrophy-focused plans often work at 65% to 80% for sets of 8 to 12 reps, taken close to failure.
Percentages assume your 1RM is current. Recalculate every four to eight weeks, or use autoregulation such as reps in reserve (RIR): stop a set when you feel you have two reps left.
Limits and Safety
Daily strength fluctuates with sleep, stress, and nutrition, so a planned 85% may feel like 90% on a bad day. It is fine to reduce the load. Warm up thoroughly with progressively heavier sets, and use safety bars or a spotter on heavy lifts.
If your estimated 1RM comes from a set of 10 or more reps, treat the percentages as approximate; use a recent set of 3 to 5 reps when possible.
Frequently Asked Questions
How many reps can I do at 80% of my 1RM?
On average about 8 reps, although this varies by person and exercise.
What percentage of 1RM is best for muscle growth?
Roughly 60% to 85%, as long as sets are taken close to failure.
How often should I update my 1RM?
Every 4 to 8 weeks, or whenever your strength changes noticeably.
What is RIR?
Reps in reserve: how many more reps you could have done before failure.
