RMR FAQ

Good to know.

What is RMR testing?
Resting metabolic rate testing measures how many calories your body burns at rest, directly, with a metabolic cart — your true baseline instead of an estimate that can be off by hundreds of calories.
Why does RMR matter?
It's the foundation of any nutrition plan. Your real number lets you set accurate calorie and macro targets for fat loss, performance, or body composition — without guessing.
How should I prepare?
Best done in the morning, fasted (no food, caffeine, or exercise beforehand). The test itself is just 20–30 minutes of quiet, relaxed breathing.
Can I do RMR and VO2 max together?
Yes — many clients do both in one visit for the full picture of metabolism and cardiovascular fitness. Both are included in our Apex membership.
