Spin Bike
A studio cycling session on a weighted-flywheel bike, logged by time.

How to do it
Setup
Saddle at hip height standing beside it, knee soft at the bottom of the stroke, cleats or cages set.
Steps
- Ride the session's profile – seated, standing, sprints.
- Keep the resistance honest under the cadence.
- Log the class by time.
Common mistakes
Spinning air: cadence without resistance is theater; load the wheel. Standing with no resistance: the knees take the flywheel's kick. Saddle too low: the knees complain by ride's end.
Breathing
Steady, rising with the profile.
