The 3 Repetition Maximum (3RM) is often considered as the best method for assessing the absolute strength capacity of individuals in non-laboratory environments, behind the 1RM. It is simply defined as the maximum load an individual can lift for three repetitions with correct technique.

Equipment Required: Access to free weights and a barbell, test administrator x 2 (one spotter and one to record results), stopwatch

Procedure:

1. Participant performs a warm-up with a self-selected load that will allow them to complete a minimum of 8-10 back squat repetitions.
2. Participant rests between 1-5 minutes (time will be agreed by both participant and test administrator).
3. Participant now selects an increased load that will enable them to complete 5 back squat repetitions.
4. Participant rests for the agreed upon time (between 1-5 mins).
5. Participant now increases the load again and begins to attempt triple back squat repetitions. Participant should continue to attempt triple back squat repetitions at increased loads (10-20% increments) until a 3RM is achieved.
6. Rest periods should remain at the agreed upon duration between each triple repetition attempt, and this time should remain between 1-5 minutes.
7. If multiple 3RM tests are being completed on the same day, it is recommended that all test exercises should be separated by a 5-10 minute rest period.
8. Participant inputs their largest load lifted for 3 repetitions into SharedGoals by clicking on the green “Add score” button.
