Instructor: Jessica Reiss is a long time athlete, having played with USA volleyball and coached in college. She is a certified personal trainer with numerous group fitness certifications and has worked with One Boulder Fitness for three years.

What is the workout? A high intensity interval training class that follows a tabata format. Tabatas are 20 seconds of high intensity exercise followed by 10 seconds of rest. Reiss chose four exercises and students completed eight rounds of each exercise. She included squats, lunges, pushing, pulling, twisting and bending drills. The exercises balance each other while providing a full body workout.

With only 30 minutes on the clock the workout was fast and there's no wasted time. The desire to chit-chat and mess around is present in all group fitness classes, but Reiss puts the kibosh on lollygagging. If you can hold a conversation then you aren't working hard enough.

What's different? It is 30 minutes of high intensity exercise, made to fit into your busy schedule. One Boulder is the only gym in downtown Boulder, an area notorious for high rents and limited space. Classes are catered to people that work or live downtown.

Not everyone can fit in a full hour of exercise during their lunch break, so the classes are broken up into 30-minute blocks. From 7 a.m.-6 p.m. they offer numerous half hour classes. People who have more time can take the classes back-to-back. The classes switch between cardio and strength or core focused.

Reiss was creative with her workout. She came up with fun Olympic-inspired exercises while the games were broadcasting. We did pseudo curling drills and mountain climbers that ended in jumping high fives with our partners. "I try to get people to interact with each other and have that team aspect," said Reiss.

Cost: $99 a month gets you access to the gym and all the classes. If you just want to use the gym without the classes the price is $77 a month. Check out their website, oneboulderfitness.com, for all the perks of membership.

Level: Reiss knows her students well and she gave her students numerous variations if she knew they wouldn't be able to safely complete an exercise. High intensity is still the name of the game, so no slacking even if you take a lower stress variation.

"The intensity is important, but it doesn't have to be the same demand for everybody. I think everybody gets to work on their own perfection," said Reiss.

When: Cardio-Tabata is at noon-12:30 p.m. on Wednesdays and Fridays. The gym offers more 30-minute cardio and strength training classes throughout the day, Monday through Friday.

What to prepare: Bring workout clothes and water. Towels and showers are provided.

Muscles worked: This was cardio heavy and I was sweating up a storm. My gluteus burned like fire for two days after. The exercises change with each class to keep your body guessing.

What I loved: It was fast and efficient. I was away from work for 45 minutes and I didn't have to drive through Boulder traffic.

What I didn't like: The gym is small by comparison to other gyms in Boulder, a function of its downtown location. Space is tight in the workout room, but it's manageable. A little like bumper cars, but Reiss uses the space well.

How I felt after the class: Squeezing in a quick workout in the middle of a busy day was a nice way to take a step back from work. Stretching my legs after a morning of sitting helped my tight, sedentary muscles.
