You don’t need
another reset.

You already know how to work hard.
The challenge is building a training and nutrition strategy that can survive your actual life.

Careers get demanding. Kids need you. Travel happens. Bodies change. Schedules get disrupted.

R|8 isn’t about being perfect. It’s about knowing your standard, adapting when necessary and never allowing one difficult season to become a complete restart.

Adapt the execution.
Maintain the standard.

Build strength. Protect your capacity.
Know your baseline.

Become hard to derail.

The R|8 method

Fitness that keeps up with your life.

01

Strength

Build and preserve muscle and strength so your body remains an asset as you age.

02

Nutrition

High-protein, nutrient-dense nutrition built around your goals and realistic enough to work in your actual life.

03

Capacity

Develop the conditioning, mobility and work capacity to continue doing what you expect your body to do.

04

Longevity

We aren’t training solely for what you want your body to look like next month. We’re protecting what you want it to be capable of doing decades from now.

The goal isn’t smaller. The goal is stronger.

Protect your edge. Train for the long run.

Meet Rachelle

I don’t coach a life I don’t live.

Rachelle Tuffly has spent more than two decades coaching strength, conditioning and human performance. A former collegiate athlete with a background in Health Science and Kinesiology, she’s coached athletes, teams and adults across multiple stages of life.

She’s also a mother, business owner and athlete who continues to hold herself to the same standard she asks of the people she coaches. R|8 grew from that experience. Because getting older doesn’t require becoming less capable.
