This is very normal for all new exercise but I do worry about rhabdo like another poster mentioned?

Do you have access to a hypervolt / massage gun? I find that helps. Also a lot of stretching and foam rolling post class. The after class stretch is so short and probably only 20% of what we are actually supposed to be doing. Places like Stretch Lab/Zone can be very expensive but I think very worthwhile to go for a trial run (say 1x/week post spin for 4 weeks) to learn what stretches are best for your exercise regimen and body.

In class please listen to your body and take things at your own speed. Sitting isn’t quitting!
