I Did Flywheel Every Day For a Week and Here's What Happened

Flywheel is more challenging than any other indoor cycling class I've done, especially since it emphasizes turning up the resistance (or torq). Because of this, your hamstrings are constantly being worked. After a few days of heavy rides, my hamstrings got super tight; so much so that when I met with a trainer, he specifically stretched out my hamstrings and told me to keep stretching them since they were incredibly tight.

I'm usually pretty lazy about stretching, so I made an effort to foam roll for about 20 minutes and it made a huge difference, but they're still tighter than normal.
