What is your favorite, most effective, group fitness class your recommend to your clients?

Hello Lawrence with Gym Insight,
My personal favorite is Punk Rope; because, it incorporates a balanced total body workout which is regressed and progressed to the class participant with various games, drills and lots of laughs. Everyone can use a jump rope; it is the way the jump rope is used that makes the class interesting and enjoyable for all ages and fitness levels. I enjoy conversations with Tim Haft, the creator of Punk Rope, who keeps us Punk Rope Instructors updated.
Thank you,
Natalie aka NAPS 2 B Fit.
