For the most part, I have mixed feelings about hybrid classes at the gym. If they're not done right, I feel like you don't get a good workout and you get cheated out of the part of class you find most fun.

So going into last night's Bike and Ball class, I wasn't sure what to expect. The class was to be 30 minutes of spin followed by 30 minutes of strength training using only stability balls, medicine balls and other weighted balls.

It ended up being one of the most fun classes I've ever taken largely thanks to the instructor. She was high energy throughout the class and played awesome music.

You know you're going to get a good workout when the instructor walks in to the spin studio and starts class by saying, "The bitch is back."

I worked harder in that 30 minutes of spin than I have in some full-length spin classes. After sprints, hills, and intense seated climbs, we hopped off the bikes and headed to the fitness studio for the strength training portion of class.

After five minutes, my arms were like mush and all I was doing was holding a stability ball over my head. We hadn't even touched the medicine balls.

When we did, the instructor had us work with partners. I felt like I was at middle school basketball practice. We did bounce passes and chest passes and then rounded things out with some soccer moves.

The whole time it just felt like I was playing, not working out.

If you're gym offers a hybrid class like this, I definitely recommend checking it out. The hour flew by and I got one of the best workouts I have in a long time.
