Hi Patty. I’ve not heard of this but I agree with Stephen (awful). I can’t imagine that everyone in a group class would want this, and that it could cause some sensory problems with certain members in the group so why “go there?” Hmm, sometimes “change” for “change sake’ is NOT such a great idea.
I’ve seen strobe, disco and blacklights used in varied combinations in some class formats, typically for special events. BTS Groove and Zumba are two formats I’ve seen special lighting used in class (no experience with Les Mills) – lends to the “club” or “party” atmosphere these formats foster. Again, it’s usually for special events, charity/fundraisers or launch parties instead of an everyday occurrence.
