1RMs are a 1 Rep Max.

1RMs should be included in your strength training programme, but should not be the only method you use.

You should work up to being able to perform a powerful 1RM, by starting with at least 6 reps and working your way down while increasing the weight.

Rest at least 2-3 minutes as you work towards your 1RM, and even up to 4-5 minutes when you are ready to lift as heavy as possible.

Be sure to utilise 5x5s to help get stronger for your 1RMs.
