Estimate One-Rep Max With a Conversion Chart

Instead of testing a true 1RM, do as many reps as possible with a challenging but safe load and use a conversion chart to estimate 1RM.

“You can use what are called repetition conversion equations. So put on a load that you think is kind of close to your maximum and just do it for as many reps as you can.”
