spinning into the winter

As the official start of the winter gradually approaches, I focus on spinning and weight lifting. I rested well on Monday, so Tuesday I was pumped: I started off with 12min sauna; 45min cycling; 15min weight lifting for the arms; 45min rpm class; 10min weight lifting for the arms; 1hr spin class; 15min weight lifting for the arms and lunges; 15min sauna. What do you call that, spin and weight intervals?
Today will be quite similar at the gym, though I would like to do some rowing and squats and lunges, too.
