Testing your one-rep max (1RM) is a huge milestone in training — but doing it at the wrong time can leave you disappointed, injured, or both. So how do you know when you’re actually ready to max out? Here’s what lifters and coaches agree on.
Your 1RM is the maximum weight you can lift for a single rep with proper form. It’s a benchmark for strength, used to program training percentages and measure progress. But it’s also a high-risk, high-effort lift that requires timing and preparation.
Ideally, you should peak for a 1RM — even if you’re not competing. This means reducing volume, increasing intensity, and tapering fatigue in the 1–2 weeks before max testing.
Learn more about peaking in our guide on how to peak for a meet — the same principles apply.
Most lifters only need to test every 12–16 weeks — sometimes longer. Testing too often eats into training time and increases injury risk. For general lifters, 2–3 times per year is plenty.
According to a 2019 study on tapering and performance, strategic fatigue reduction can improve max output by 2–5%. Timing matters more than sheer effort.
If you’re not quite ready — or don’t want to risk injury — use a rep-max calculator to estimate your 1RM. For example:
These aren’t perfect, but they help guide your programming without testing under fatigue or pressure.
No — you're more fatigued and your recovery is impaired. Save max testing for maintenance or surplus phases.
Not ideally. Maxing out 2+ lifts in one session dramatically increases injury risk. Space them out across separate days if possible.
It happens. Reduce weight, retest another day, and adjust your training block to address the weak points exposed by the miss.
