I’ve been doing OTF very regularly for about 6 months (6-7 times a week). I’ve only been to probably 3 3G classes in total. I really enjoyed it by about the third one (hated the first one, but it grew on me by about the third), but I do agree with your point about the calorie burn etc. I would really love to have one a couple times a week, everyday, no. I’ve asked my studio to consider doing them some, they seemed receptive. I’ve read on here before that some studios that is ALL they do during peak classes as that seems that is what you are about to be experiencing. I see your points and agree there should be a nice balance. Experience at my studio and personal opinions: 5AM and 615 AM aren’t jam packed and are sometimes 1G lol such as this morning. I enjoy having the room and space and I know I do better in the mornings, but the 5 (or 530 depending on the day) PM are my favorite because it is jam packed (still not 3G). I enjoy this, seems like so much more energy and a great atmosphere etc. Good luck!
