About Merkaki CrossFit

Everything you’ll need to transform, under one roof.

Our transformation program is tailored to each individual member. You will be paired with an expert coach that matches your style and needs. All ages, injury history, goals, fitness levels and experience are welcome!

Private Coaching

So we can focus on exactly what you need while keeping a close eye on your progress. Your coach will adjust your program as needed, keeping you in momentum!

Group Workouts

Bootcamp, Strength and Conditioning, Cardio Kickboxing, CORE, and more so you can burn a ton of calories each week while never seeing the same workout twice.

Nutrition Plans

Healthy nutrition plans based on the foods you enjoy. We teach you how to balance healthy foods with everyday life so you don’t put weight back on after your “diet” is over.

Goal Setting and Tracking

Weekly goal setting and tracking with our medical-grade Body Composition Analyzer to hold you accountable while also knowing exactly what’s happening with your body as it changes.
