The most precise picture of how your body clears lactate — and the intensity you can actually hold.
The maximum amount of oxygen your body can use under load — the single best-studied marker of cardiovascular fitness.
What your body burns at rest, measured rather than estimated from a calculator that has never met you.
You test in your own discipline — treadmill for runners, ergometer for cyclists, pool for swimmers. The data is only useful if it comes from the movement you actually train. The session is staged, then read back to you in the room. You do not get emailed a PDF and left to interpret it.
A blood lactate test is $350, a VO2 max test is $275, and an RMR test is $175. A combined VO2 max and RMR test in one visit is $450. Every price includes the consultation and a full explanation of your results.
The lab is at 1736 Ashland Avenue, Santa Monica, CA 90405, and serves athletes across Los Angeles, the Westside, Venice, Culver City and the South Bay. Call (858) 361-4733 to book.
