We have a hard time getting ourselves solo to the gym too. That is why our group fitness classes are so effective- we are a comprehensive and results-driven.

Even with the best of intentions, gym memberships are often under-utilized. One of the most effective ways of boosting your motivation and performance is with group fitness classes.

Research shows that the risk of membership cancellation is 56% higher in gym-only memberships as opposed to those who enroll in group exercise. Working out with others is fun, engaging, and delivers results. Furthermore, professional trainers keep you moving while also ensuring proper technique.

Group Fitness Classes for Strength and Conditioning 

Doing the same exercises over and over leads to a fitness plateau. You are likely unintentionally neglecting a few muscle groups too. Not only does this have aesthetic results, but you are at greater risk of injury. 

Group fitness classes help you to switch up your routine. At NDB Fitness, there are professionally-led specialized group classes for safely increasing your strength and muscle tone. 


Our yoga classes are a great alternative to high impact and intensity classes if you want to focus on core and flexibility. Yoga is an excellent class to center yourself and relax, giving yourself a break from the business of your typical routine.

Cardio Kickboxing

These high-intensity classes combine martial arts with cardio, set to face-paced music. It is non-contact, meaning that all punches and kicks are thrown into the air or onto pads rather than to another person. 

Heavy Lifting

Group heavy lifting classes rely on free weights, dumbbells, and exercise bands rather than weight machines. These classes work all the major muscle groups in the body. 

What is a Fitness Boot Camp?

Fitness boot camps are almost always a form of interval training that incorporates elements of speed, aerobic/cardio, and strength. There are bursts of high-intensity exercise followed by brief, low-intensity recovery periods. 

A boot camp provides a full-body workout. The exercises are unique and varied, which keeps you more engaged. Because of the intensity, boot camps burn more calories in a shorter period of time so they are often appealing to those with limited time to hit the gym. 

Not only does a boot camp maximize fitness results, but it also offers camaraderie and socialization amongst participants. This serves as a psychological boost too!

Don't Forget About Nutrition 

If you really want to see results exercise alone isn't enough. It is important to give your body the nutrients it needs through a proper diet. 

A nutrition specialist can formulate an eating plan based on your specific needs, habits, body type, and goals. 

At NDB Fitness, there are even occasional nutrition challenges that are free for all members. Sometimes a little bit of friendly competition works wonders for motivation!
