Our Mission:

Inspiring People to Move

About Us

MOSSA has a long history of inspiring millions of people to MOVE. Through the years, our business has touched every part of the fitness industry. This company has its roots in successful health club ownership during the 1970s and 80s, and we were the originators of the step fitness craze in the 90s. Today we are the leading developer of professional group fitness programs for health clubs and fitness centers.

Spearheaded by Cathy Spencer-Browning, VP of Programming and Training, MOSSA has the most comprehensive and thorough Program Development process in the fitness industry. Over 300 hours are poured into each and every workout to ensure participants’ enjoyment and success. This includes an unsurpassed, methodical Testing Phase that consists of 150 test classes for just one workout. The Testing Phase of Program Development guarantees the programming of music and exercise is motivational, safe, and effective. The MOSSA Program Development Team partners with SAIFAM, our exclusive music supplier, which customizes and engineers songs to ensure MOSSA workouts motivate participants with the highest quality musical experience available.

MOSSA offers eleven professional group fitness programs for health clubs, gyms, and YMCAs: Group Active, Group Blast, Group Centergy, Group Core, Group Fight, Group Groove, Group Power, Group Ride, R30, 3D30, and MOVE30.



The 70’s & 80’s

MOSSA’s journey began in the 1970s with the drive, passion, and spirit (not to mention frustration) of our leader, Rich Boggs. After 10 years of working for corporations including Proctor & Gamble and Bristol-Myers, Rich’s tremendous entrepreneurial spirit was too controlled, and his health and weight were out of control.

Rich made the decision to get moving! His desire for positive change led to the development of Sportslife: The Science of Good Health. This chain of seven full-service health clubs in the metro Atlanta area serviced over 45,000 members. The experience of owning and operating clubs for nearly 15 years provides a strong foundation for the success of the MOSSA professional group fitness programs and consumer home workouts today.

The Step

The 90’s

In the late 1980s, a new phenomenon was taking shape in the Sportslife clubs – step aerobics classes . . . on wooden benches! To capture this excitement and share it with the world, we developed The Original STEP and started The STEP Company. At that time, over 13 million people a week were part of the step fitness craze, and MOSSA introduced The STEP in over 25,000 clubs in the US and Canada and many more worldwide. The Original STEP is now a staple of the fitness industry, used by millions of participants each week.

Bodytraining Systems


In the late 90s, MOSSA was known as Body Training Systems, and we brought pre-choreographed programs to health clubs in the US and Canada. In 2005, MOSSA launched its own professionally developed programs, a comprehensive instructor training system, a sales and marketing system, and an extensive management system that includes software and resources to enable health clubs to maximize their group participation and be more profitable.



MOSSA’s goal is simple: to get more people moving. We accomplish this goal by partnering with top-quality health and fitness facilities, as well as international distributors around the world. Everything we do at MOSSA is grounded in our never-ending commitment to create the best group fitness programs and home workouts.

We believe that a great experience with an engaging instructor and an amazing playlist can help people find a certain level of fun in fitness. Through innovative programming and an inclusive mindset, we want to encourage more people to take care of themselves, by taking more time to move. We believe movement is medicine. It can reduce stress, relieve anxiety, improve cognitive function, boost your immune system, release feel-good endorphins, and ultimately, prepare you to move younger, longer. LET’S MOVE!
