‘Boot Camp’ workouts have gained popularity in recent years, but it’s important to remember that they’re not all the same. Some offer exciting promises but fall short on delivery. With our fitness classes at Plainfield Fit Body Boot Camp, you get a formula for success backed up by real life results. We help people from all fitness backgrounds achieve superior fat loss in half the time.

Our Fitness Classes in Plainfield With Superior Afterburn

Our exciting Afterburn workouts are proven to get the job done. That’s because the whole thing is built on trusted scientific research that shows us the best way to sustainably burn fat. The formula is so efficient, we only need 30 minutes of your time to produce amazing results!

Every session yields up to 35 hours of progress that includes fat loss, lean muscle growth, and renewed energy!

This incredible payoff is accomplished through High Intensity Interval Training (HIIT) and Active Rest Training. This creates a dynamic of constant movement that has some of your muscles active and others at rest. This lifts up your metabolism and opens up the extended window of post-session results.

With the boost of energy you get from each workout, you can accomplish more in your day and feel more confident going about your life. It’s a terrific way to make tangible progress that helps build momentum and cement fitness as a part of your routine. With convenient workout times that avoid the busiest parts of your day, it’s even easier to squeeze us in.

Our unique Afterburn method brings you unparalleled success that also saves you time and empowers you to live a more active life.

Afterburn: Twice The Workout In Half The Time

Our signature Afterburn workouts combine High Intensity Interval Training (HIIT) with Active Rest Training to produce 30 minute workouts that burn twice the calories in half the time and keep the metabolism running at a higher rate for up to 36 hours post workout.

Compare our 30-minute sessions to other fitness classes, which typically last 45 minutes to an hour. With our Afterburn workouts, you don’t need to choose between results and convenience -- you can have both!

Research shows that shorter, more intense fitness classes (HIIT) and workouts that activate one set of muscles while others rest (Active Rest) lead to faster and more sustainable weight loss. It turns out, what’s best for your schedule is also best for your health.

Best of all, our 30-minute sessions are scheduled throughout the morning and evening to fit your schedule!

While many fitness classes operate outdoors, we recognized early on that this leaves your workout open to way too many interruptions. An outdoor fitness class can be shut down at any moment by anything from bad weather to city restrictions on public spaces.

When we took the boot camp fitness class indoors, we took it one step further. We realized we had an opportunity to create a welcoming space and community -- a home away from home.

We recognize the courage it takes to commit to a fitness journey. That’s why we’re committed to maintaining a trendy, clean, modern space where you can bond with others on that same journey.

When you walk into a Fit Body Boot Camp, you’ll recognize in an instant that it’s more than just a fitness class. It’s a place where we recognize and celebrate each other’s victories. It’s a place where we donate to the causes that matter most to us.

It’s YOUR place to meet positive, like-minded people who will hold you accountable to your dreams and motivate you every step of the way.

Group Fitness Classes: Get Results, Save Money

Our group fitness classes began with one simple question: How could we make the powerful results of 1-on-1 personal training available to more people?

The answer: provide the benefits of 1-on-1 training by keeping the same high quality while splitting the cost among 20-30 people per session. The key to that is our certified fitness coaches -- who are basically the ultimate version of personal trainers.

They go beyond the basics of instructing a fitness class -- they provide the personal accountability you need to reach the body of your dreams and keep it for good.

personal accountability


Our fitness coaches are experts at creating weight loss results and keeping you safe and motivated both on the floor and off the floor. They don’t stop at correcting form and demonstrating exercises -- they get to know you.

They learn your unique strengths, challenges, goals, and desires. They help tailor YOUR fitness classes to your own lifestyle and needs. Even when you leave boot camp, they’re available through email and Facebook to provide healthy tips and inspiration.

Our fitness coaches strive to make every boot camp session the best 30 minutes of your day -- and they also recognize that the other 23 ½ hours of your day still count! That’s why they’ll even check in outside of boot camp to help you stay on track with your diet and healthy lifestyle.
