dos Remedios and Friends

No, nothing like Fox and Friends: these guys actually have brains. Here are three of the most popular conversion charts for "one repetition maximum" or 1RM. That is the amount of weight that one can lift only one time with good form.

It is important to know your 1RM so that you can properly load and progress your lifts. generally, you must lift over 75% of your 1RM in any given lift in order to build muscle and increase strength. That might seem like a lot, but consider that you can get around 10 repetitions at your 75% 1RM.

Of course, the best way to get your actual 1RM is to do 1RM testing. But that can be dangerous and too time-consuming for many people.

Here's a  summary chart you can you use to estimate your 1RM. experiment a bit to see which one you find most accurate ( professionals appear to use the Brzycki most often.) Blank spaces mean the % matches the value above. "-" means no value provided.

Oh, and stay away from Fox and Friends. It will rot your brain. I mean it.
