Using a fitness calculator is the perfect way to make every part of your fitness journey more systematic and successful. Here are just a few ways they can help you optimize your training and nutrition toward your goals.

• Use a one-rep max (1RM) calculator to choose weights that line up with your goals: building muscle, losing fat, or gaining strength or explosive power. And you don't even need to know your 1RM to use it!
• Calculate your maximum heart rate (MHR) to tailor your cardio to specific goals and difficultly levels.
• Determine your ideal daily calories or macros to make more strategic food choices to meet your health, muscle-gain, or weight-loss goals.

These are just the beginning, though. We also offer calculators for body type and other body measurements, a wide range of nutrition and supplement goals, and calculators to help you succeed in Bodybuilding.com's most popular training programs.
