Frequently asked questions
How do I find my training heart-rate zones?
The Heart Rate Calculator estimates your maximum heart rate and target zones by age, so you can train at the right intensity for endurance or fat burning.
What is a one-rep max and why calculate it?
Your one-rep max is the most weight you can lift once. The One Rep Max Calculator estimates it from any set so you can program training weights without maxing out.
