Two churches I used to attend said so too. 
BUT, it was BodyBalance (Pilates + Tai Chi + Yoga), Pilates and
Yoga that kick-started my exercise about two years back and if not
for those, I would still be a couch potato!
So, I don't know how I'm going to answer the church if I ever get
confronted but I'm continuing with my Yoga and Pilates!
