Don't be afraid of spinning class people! It's one of the best things you can do to push yourself and get better endurance and leg strength. I promise it won't hurt after 3-4 classes. Your body just has to get used to it. Plus, the best thing about spinning is you can do it at any level of fitness because you're in control of the resistance on your bike. It's a hard workout and it's easy to make up excuses not to do it ( please don't hate me for saying this! ) but it's definitely worth it
* I realize spinning can't be for EVERYONE but I also believe in giving it a few chances before swearing it off forever *
