Instructions & Guidance

Kathletics takes the guesswork out of your lifts by providing exercise demos and explanations made directly by your coach so you know exactly how to do the exercise. The demos paired with reps, sets, rest times, RPE, and tempo (if applicable) makes it so you’re feeling confident in your lifts and progressing week after week.

02

Track & Progress

Watch your consistency pay off! View your exercise history within a specific exercise, monitor your training and habit adherence, or check out your mileage completed. You'll never have to rely on memory to know what weight you last lifted or how many miles you previously trekked again. You can even see what your estimated 1 rep max, 5 rep max PR, 10 rep max PR, and largest volume lifted. 

03

Athlete Resources & Community

Access exclusive resources and community forums for additional support and accountability outside of your coaching program. These built-in tools help you elevate your training, support your recovery, and encourage participation in our community of like-minded athletes.

What people are saying

Katharine was sure to listen to my goals and priorities, and she taught me how to properly and effectively lift weights, making sure I had no pain/offering variations for certain exercises. I am so so happy with my results, and I feel so much more confident training on my own from everything she taught me.

Chrissy

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!

Breanna

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.
