I have the Peloton app and I also have Les Mills on demand which I much prefer.
The endless 'come on peloton' , 'are you with me peloton' etc and the non-stop namechecking of cyclists who are doing there 100/200/500th cycle with 'bubbybubcakes happy 100', 'detroit mama, 200th ride today, congrats' thing drives me absolutely bonkers. Its like exercising with a load of toddlers who all need individual attention from the teacher.
Les Mills on the other hand, particularly the RPM ones, just get on with it, have much slicker production on the music and co-ordination front, and I prefer the other classes they have such as body pump and attack, to the extra classes peloton has.
Its interesting what you say about the music on Les Mills, as I think its better than on Peloton, but then I'm very uncool so I wouldn't know a club hit if I tried!
I also really like the Studio SWEAT cycle classes that are free on youtube, not as slickly produced, its literally pointing a camera at an instructor in a real class, not a studio, but they have very personable instructors.
Finally which is a 8 minute tabata spin class (free on youtube) is absolutely amazing for increasing cardio fitness, but it literally knackers me out for the whole day, so I have to do it at night before bed. Its that leathal
