Your one stop shop for strength, cardio, and performance training.

increase strength, endurance, and performance through personalized hybrid training.

Hybrid training is just a fancy word for improving strength & cardio simultaneously

For years, you have been told to choose one or the other: cardio OR strength train. But BOTH can co-exist and improve at the same time. Cardiovascular and strength training both have benefits to your health, longevity, and overall well-being, so why not do both?

Personal Trainer

We hybrid train because cardiovascular training + strength training are equally important

Do any of these ring a bell?

Struggling to figure out how much and what type of strength training and cardiovascular training is best for your goals.

Working out without a plan then getting frustrated when you don't see improvements in strength, endurance, or performance.

Getting intrigued by a new distance or duration for hiking or trail running.


Wanting to dabble in exploring on dirt after primarily being a road runner.


Searching for accountability and an individual program after trying other cookie cutter programs.

Yup, the bells be ringin'.

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!

Katharine not only made a personalized workout routine and schedule for me, but she's also made accommodations for my health and injury to make workouts fun but good for my body!

Personal Trainer + Running Coach

If you’re like me, you have a schedule that requires a bit of tetris to fit in workouts.


You want to follow a program that allows you the flexibility to get workouts done on your own time. Consistently progressing is important to you, so you want an efficient and sustainable training program to help you build strength and endurance over time. I aim to create a program that allows you to get your lifts and cardio completed based on your calendar, so you can enjoy the rest of life's adventures.
