When programming for CrossFit affiliates I do not to test for 1RM’s anywhere near as close to as much as I used to. The benefits far out weigh the risks in my opinion, but some people do like to use it as a measurement of their improvement over a period of time.
The truth about 1RM testing tho it is so much more of a neurological test than it is a strength, because you could much stronger than you were prior to the cycle. Then though when testing comes around you have an off day, you don’t PR your squat and boom your whole last training cycle was a a waste of time.
The above is not true, even though you did not hit a new 1RM doesn’t mean you didn’t get stronger, it only means you did a poor job displaying your improvements that one testing day.
What I like to do to measure progress is work up to a quick heavy singe for my main lifts on a weekly basis. If the same weight start moving faster week to week or I can bump them up a little bit I know I’m getting stronger
