Preparing For Your Test

The test itself is quick and straightforward. You’ll lie down on the DEXA table while a mobile arm performs a 7-minute scan.

For maximum accuracy across tests, try to keep your circumstances as similar as possible. Scan at the same time of day and follow the same eating schedule, for example.

Our table has a maximum weight limit of 350lbs. We are unable to test pregnant women.

Do not consume any calories for 3 hours before the test (water is fine)

Do not consume caffeine, nicotine, or any other non-prescribed stimulant or supplement 12 hours before the test (preferably 24 if you can manage)

Do not do an intense workout 24 hours before. We don’t want you burning out early

Low intensity exercise is fine. Keep it in line with your regular, sustainable exercise levels

Come wearing clothes you can comfortably run or bike in

Bring a water bottle for after

If you have asthma, bring your inhaler

If you’ll be doing a cycling test, bring your bike for us to connect to the Wahoo Kickr. We’ll remove the back tire and connect it to the trainer.

VO2 Max measures the maximum amount of oxygen you can consume—keyword maximum. You're going to sweat and get your heart rate up. As Deadpool would say, “Maximum effort."

But don’t freak out! You start very slow—a slow walking pace—and gradually increase intensity. Your maximum effort won’t last long (that’s how we know it’s maximum). For reference, most people end up traveling about 1.5 miles on the treadmill, half of which is at a walk or jog. You won’t be Usain Bolt-level sprinting.

Don’t consume any calories for at least 5 hours before the test (12 hours is ideal. Lot’s of people test fasted in the morning).

No exercise for 12 hours before testing

Don’t consume caffeine, nicotine, or any other non-prescribed stimulant or supplement 12 hours before the test (preferably 24 if you can manage)

If medically possible, please refrain from taking thyroid and ADHD medication 48 hours prior to your test.
