More than 40 years ago, Arin and Suzy Harrison opened a modest fitness center in Venice Beach, California and began a tradition of commitment, passion and dedication that is now practiced at more than 600 locations across the globe. The Harrisons took their knowledge from training with world famous Harold Johnson and opened Intensity on a loan. Today, the gym is worth over $10 million. "We opened Intensity because we wanted to help the neighorhood," Arin said in an interview in 2004. "We heard a bunch of complaints from our friends and neighbors that there was no nearby gyms in the area, and we thought 'Hey, we have experience for this, we can open a gym ourselves!' And so we did." Our gyms are built to help people realize their goals and find their inner strength. We combine the most diverse amenities in the industry with the best personal training to deliver the ultimate fitness experience..
