If you want to find out the heaviest weight you can lift just once for a specific exercise, you can use an online tool called a one-rep max (1RM) calculator. Here are some easy-to-use options:
- [One Rep Max Calculator – Strength Level]: This tool lets you enter the weight you lift and how many times you can lift it to guess your 1RM. It also shows you a chart of how much you should lift for different numbers of reps, which is handy for making a workout plan.
- [One Rep Max (1RM) Calculator – NASM]: This tool helps you figure out the most weight you can safely lift for moves like the squat, bench, and deadlift. It’s really useful if you’re doing the Maximal Strength stage of the NASM OPT™ Model.
- [One Rep Max Calculator (One-RM Calculator) – Fitness Volt]: This simple tool asks you to divide the weight you lift by the percent of your 1RM to learn your one-rep max.
- [Bench Press Calculator – Find Your 1RM]: If you’re looking to calculate your 1RM specifically for the bench press, this tool uses a special formula based on the weight you lift and how many times you can lift it.
- [The Best 1RM Calculator: Calculate Your One Rep Max]: This tool estimates your one-rep max based on how many reps you can do with a certain weight and gives you numbers for your 1–10RM.
Always remember to lift weights safely. If you’re new to lifting or not sure about your form, it’s a good idea to talk to a fitness trainer.
