Fitness Assessment: Your First Step to Smarter Training

Why does it work?

Whether you’re starting an exercise regimen, looking to find your "Zone 2" and VO2max, refining your nutrition demands, or restarting after injury, this test gets you all the data you need. The results provide you with customized, actionable recommendations and training zones based on physiological conditions instead of estimates.

“The information I obtained from the lab at Endurance has been of great benefit to my training. With work and family commitments, ironman training used to take over the rest of my life.  I'm training less now, but more efficiently, and my fitness has never been better. Working with Endurance Team has been a life changer for me.”   - NR
