One-Rep Max Warm-Up Calculator
General vs. Specific Warm-Up
A good warm-up can make all the difference in your training and especially when you are going for a one-rep max or PR attempt. Warming up lowers your injury risk, increases your strength, and improves your technique and coordination.
A good warm-up consists of a general and a specific part.
- The general warm-up should warm your entire body up and prepare you for activity. It can consist of 5–10 minutes of light exercise on a cross-trainer or a rowing machine, or simply some light mobility drills.
- The specific warm-up should warm you up for your specific task at hand. For example, if you are going to do bench press, then your specific warm-up should consist of gradually heavier sets of bench pressing. This is what the calculator above shows you.
