I often get bored with workouts, especially in the gym, but for TWO YEARS I have been trained, challenged, encouraged, entertained and surprised by how enjoyable (but hard!) Justin's workouts are. If you sign up for multiple locations, you hit the jackpot. His wife, Rachel, teaches some of the TOUGHEST most cardio-riffic classes I've ever tried. Combined, they are the workout dream team.

I’m 38 and the thought of boot camp would send me running, the other way. But I figured, heck, why not. It is the best purchase I’ve ever made!! You can do it, no matter age, lifestyle, body type, doesn’t matter. It’s so worth it. I love the Morley Field location, I’m just so happy I was brave enough to take the step, way forward.

``Wonderful instructors, exciting work outs that change constantly, motivating group of people.`` -Jessica G.
In Person & Online

With the option of live interactive online personal training and in-person workouts, you never have to go to a busy gym or miss a day of training because you're running out of time. We are everywhere you are.

Cross Functional Training

Utilizing High Intensity Interval Training & Functional Exercise means that we accomplish more in less time. Our style of training will improve everything athletic that you do.

Outdoor Workouts

Research on outdoor physical activity shows significantly greater positive effects on emotional state, muscle activation, and fatigue compared to equivalent exercise done in a gym.

Workout with pros

Rachel & Justin have more than 30 years of fitness and nutrition experience between them. Their deep passion for both drives them to keep up-to-date on the latest in the science related to personal training, nutrition, & general fitness.

Beautiful Outdoor Settings

Gyms are expensive, dirty and don't have a great views! We chose each location for the view, features relevant to our workouts and proximity to our other locations. Get either an incredible sunrise workout or sunset boot camp with all the built-in tools that make for a great class or personal training session.

Positive Attitude

We coach from a place of deep curiosity in the search for fitness and good health. Justin is a chef & foodie and Rachel has a passion for dance and nutrition, which culminate in a motivating group workout or personal training session every time.
