Energy Lab

14 Years of Energy Lab

Fourteen years ago, Jim, Bethany, John and Ted had an idea: create an indoor cycling facility where athletes could come together, train smarter and get better.

That idea became Energy Lab.

Over the years, the Lab has grown well beyond indoor cycling. The equipment has changed, technology has advanced and our services have expanded, but helping athletes learn, train and perform has remained at the heart of what we do.

Today, Tim continues that vision 14 years later, building on what they started while continuing to evolve Energy Lab for the athletes and community we serve.

To everyone who has coached, trained, tested, ridden, run, swam or simply been part of Energy Lab along the way—thank you for being part of our first 14 years.

Take the Guesswork Out of Hydration

Whether you're training for your first 5K, chasing a marathon PR, or preparing for your next Ironman, your hydration strategy should be as unique as you are.

At Energy Lab, our Precision Fuel & Hydration Sweat Test measures exactly how much sodium you lose during exercise, allowing us to create a hydration plan tailored specifically to your body and your goals.

The amount of sodium athletes lose in their sweat can vary by up to 15 times. That's why a one-size-fits-all approach to hydration simply doesn't work.

In just 45 minutes, you'll receive:
Your personal sweat sodium concentration
A customized hydration strategy for training and racing
Recommendations on when, what, and how much to drink
Guidance on the electrolyte strength that's right for you

One of the reasons we're excited to offer this service is the company behind it. Precision Fuel & Hydration works with elite athletes and professional teams across the NFL, NBA, MLB, Premier League, and Formula 1.

In fact, several teams they support are currently competing at the FIFA World Cup. Now, the same science trusted by the world's best is available right here at Energy Lab.

For most athletes, this is a one-time test that provides valuable insights you can use for years to come.

Ready to take the guesswork out of hydration?

📧 Email us at [email protected] to schedule your Precision Fuel & Hydration Sweat Test today.
