Instructor: Helen Ortiz has been teaching group fitness for two years. She teaches indoor cycling as well as a hammock class at Define.

What is the workout? A 45-minute rhythmic cycling class. High intensity and fast paced, the class is cardio-focused while adding in some strength training.

Cadence is set to the beat of the music and the pace varies with each song. "You ride to the beat of the music for every song, so that can make the resistance go up, a little faster or a little slower during different sections," said Ortiz.

Between the handlebars was a blue ball used for ab exercises during the workout. We'd rest our hands on the ball and push against it to engage our core.

Halfway through the class we stopped pedaling and picked up light weights for some arm exercises, then we started peddling again. We were in and out of the saddle, sometimes turning up the resistance then sprinting at intervals.

What's different? Most cycling classes use music as a motivator — this class uses music as a tool. "It's kind of like a party on the bike. It's a fun cardio way to get your heart rate up," said Ortiz.

More than anything, the class is dictated by the music. Students focus on dropping one foot to the bottom of the peddle stroke in time with the beat. As the beat picks up the pace picks up.

Ortiz throws upper body movements into the mix. We lowered our torsos to the handle bars for pseudo push-ups and leaned from side to side. Adding in the light weights and ab exercises was a concerted effort to include the entire body in the workout.

Cost: Single classes are usually $22 and a five-class package is $105. The gym is currently running a single class special for $18 and the five pack is $90. New clients can get one month unlimited for $125.

Level: Most people could drop into this class and get a good ride in. You might not get in sync with the beat — I certainly wasn't — but you don't have to be.

All of the additional exercises were optional. "The most important thing is first trying to keep the beat and then you can add on," said Ortiz.

When: 6:15 a.m., 9:45 a.m. and 5:45 p.m. Mondays and Wednesdays; 9 a.m. and 6:30 p.m. Tuesdays and Thursdays; 9:45 a.m. Fridays and Saturdays.

What to prepare: Spin shoes with clips are required. The studio offers rental shoes that you can borrow. Towels are also provided. Wear workout clothes and bring water.

Muscles worked: My upper abs and legs were sore the following day. All my other muscles got involved just enough to get warmed up.

What I loved: For a 45-minute class I got in a good cardio workout. I was breathing hard and sweating even harder.

What I didn't like: I don't have the coordination to time my peddle strokes to the music while attempting push-ups. Everyone else was in time with each other, like synchronized swimmers. I was the one trying not to flail around in the background. With time and practice this probably gets easier.

I had the hardest time with the music. It was so loud that I couldn't hear Ortiz most of the time. I realized, belatedly, that they provided ear plugs at the front desk.

How I felt after the class: I felt like I worked hard enough to justify devouring a breakfast burrito after class. Totally worth it.
