‘CrossFit Total’ 1RM Press 1RM Back Squat 1RM Deadlift
“A meet situation will involve three attempts, and this is a good way to determine a true 1RM.
The first attempt would be a weight you know you can do for a heavy set of three. The second attempt would be a weight you know without any doubt that you could do for a single, having just done the first attempt. And the third attempt is the weight you want to do, based on your performance on the previous two attempts.” ~Mark Rippetoe
