I am certified in Body Pump, Body Step, Sh’Bam and CX Worx. I’ve been a group ex instructor for 23 years. We see HUGE numbers in Body Pump, CX Worx and Zumba. Body Combat brings a lot of folks out too. Body Step is on the down side slightly, as well as Pilates. Boot Camps are moderately attended, as well as cycle as seen a slight increase due to RPM coming to our club. I also teach corporate Boot Camps and my numbers are about the same, if not down some from 2 years ago. I find myself constantly researching for new ideas.
