LOS ANGELES, California. – March 5, 2015 – World Gym, the iconic brand for bodybuilding and seriously fun fitness, has expanded its High Intensity Interval Training (HIIT) programs in response to millennial demand.   World Gym owners and operators have been riding the wave of popularity generated by the accelerated growth of High Intensity Interval Training (HIIT).  World Gym clubs that have always erred towards workout intensity and serious fitness have recorded significant growth in the 18-to-34 year old membership segment looking for high intensity workouts in a small group setting.   World Gym Pacific Beach owner George Jackson said, “We get through 1100 workouts a day.  HIIT is hot and driving growth of about 15%.  Both our members and staff enjoy the camaraderie that it creates”.   Furthermore, World Gym Managing Director Guy Cammilleri says, “HIIT has stripped away the intensity and group segment from a lot of mainstream mid-tier clubs with members migrating to training specific studio concepts.  World Gym really caters to the specific needs of this very fitness conscious group – we are not necessarily your mom’s gym but we do provide some seriously tough but fun workouts for our members”.   World Gym has produced an incredibly compelling video clip titled “Let’s Rock!” to support their franchisee network that focuses on HIIT and the member demographic that this attracts. Available in 15, 30 and 60 second clips, “Let’s Rock!” is driving World Gym membership growth in Australia where it is currently featured on national TV channels with great success. “Let’s Rock!” will be featured on 22 screens at LA Live, Los Angeles, on 12th and 13th March during IHRSA, the annual fitness industry trade show, as well as in Times Square, NYC on the same days.   World Gym will start a social media campaign during IHRSA that will continue in the weeks afterward that utilizes the success of the “Let’s Rock!” video to help our franchisees sell more memberships.   For more information on World Gym International, please visit worldgym.com.
