Yeah same! I've had better results in 3 months with peloton than I did going the gym for years.
My personal faves are
Matty, selina, Olivia and Andy for strength - Andy ultimate fave because of his cheesy dad jokes and how he explains every move so in depth
Kendal, Olivia and Cody for spin - kendal is a love hate relationship but she says that on the bike "hate me now, love me later", and Cody because he's such a cutie, he makes me laugh and his classes fly by! And Olivia is just a tiny demon. I like jess King too but she's a tiny bit too mother earth for me and it makes me cringe a bit
The 5/10 minute focus flows are good, I really suffer with tight quads/hammys/glutes/hips and the flows are so painful, but in a good way and I've loosened up quite a bit after doing them
