Tonight I'm teaching back to back classes...don't worry Mom, the first one is an intro class that's at best 20 minutes of effort. The second is a little messier...tonight is week 4 of strength training, so we've got a 21 minute hill in store.
I'm going to use this for the intro class...just two sawtooths (sawteeth?) so they can get the feel of the positions and cadences. I'll throw on my top 40s workout mix for this.
