Your VO2 max and the real heart-rate zones that go with it, so cardio is aimed instead of guessed.
VO2 MAX
Where your body burns the most fat and where your threshold sits, so easy days and hard days are both aimed.
VO2 MAX
Ten to fifteen minutes on a bike or a treadmill, fully supervised, with your results read back to you before you leave.
VO2 MAXA number on a report changes nothing. Prefusion Health turns your VO2 max and your zones into training you can follow, and a retest shows it moving.
Optional: the Optimization Pack adds a DEXA scan for body fat and lean mass and a resting metabolic rate test for your resting calorie burn, all three in one visit. Purchased separately.
Filmed in our New York clinics.
Book at New York City, Bellmore or Stony Brook.
Diagnostics for Prefusion Health. DexaFit NY runs the scans. Prefusion Health turns them into a plan.
