Good? As Kellogg's Tony the Tiger would say, "they're greaaaat!" That's about the only way to describe a workout that's fun, challenging, motivational and super effective, all at the same time.
Spinning classes are conducted by enthusiastic leaders, who ride with you and guide you through the session. Because they're coaching and you're riding alongside other spinners, you're motivated to do your best. And, because it's a structured routine, carefully planned to offer hard work, but plenty of active rest when necessary, too, you're guaranteed excellent exercise. In fact, some top bicycle racers attend spinning classes.
Be sure to call the club if you're new to find out when the Spinning sessions take place. Bring a water bottle, a towel and your cycling gear, and prepare to experience one of the best indoor workouts available.
