Spin Heaven: Class taught by a triathlete, distance rider. Good interval training, climbing simulations, and back to back classes so you could spin for a few hours. Excellent training, and the instructor encouraged the class to do your own thing if you wanted to work on a specific challenge or chill some base miles. (Note: Class drew event riders, CAT racers, lots of discussion about ride tactics.)

Spin Hell: Class taught by a "spin instructor". Lots of yelling, stupid jumps and hovering, and complete lack of awareness about the cardio aspect of spinning..instructor had no clue about zones and recovery. Useless training, and if you deviated from his silly routine or wore earbuds he yelled at you. (Note: A few of ladies loved him.)


It's that human thing.
