## How do you calculate one-repetition maximum?

Calculating 1RM

- Multiple the number of repetitions you can perform on an exercise to failure by 2.5, for example, a load you can lift 10 around.
- Subtract that number from 100 to determine the percentage of your 1RM.
- Divide the above number by 100 to get a decimal value.

**How do you calculate 1RM from 5RM?**

Your 5RM would be 305 x 0.87, giving you a working weight of roughly 265 pounds. The same program that asked you to do your 3RM and 5RM could alternately have said to do 93% 1RM and 87% 1RM, respectively….1 REP-MAX PERCENTAGES.

REPS | %1RM |
---|---|

2 | 95 |

3 | 93 |

4 | 90 |

5 | 87 |

### How many repetitions should be performed for each sets?

### What percentage of my 1 rep max should I lift?

To improve muscular strength, you should lift a lower number of reps (typically 6–8) at 60–80% of your 1RM; to improve muscular endurance, lift a higher number of reps (12–15) using about 50% of your 1RM.
