Sustainably Fit

The workouts feel great & it already has made my life easier to have them planned out for me. Everything is easy to follow & figure out. The videos you made for each movement are super helpful too!

Katharine is like no other trainer I’ve ever had. She truly cares about my outcomes, and puts so much thought into every aspect of my training, even the off days and (when I need it) nutrition. With her help, I’m stronger than ever, but more importantly, I’m injury-free and more mobile. I recommend Kathletics to everyone who wants to invest in their long-term health!

I love Katharine's approach to wellness and fitness. Her program is sustainable, even for busy people who don't think they have time for fitness. Katharine is supportive and goal-oriented.

Katharine has been so helpful getting me back to a regular workout schedule, after I fell off for a couple months. She’s fun to work with, super attentive to correcting my asymmetrical movement patterns and helped me create some achievable, motivating goals!
