Our Fitness Services

Jumpstart Your Health

Getting in shape shouldn’t be a punishment. It’s an amazing and empowering lifestyle decision that anyone can achieve. We believe in finding the pleasurable side of fitness, and while there may be a sore muscle or two along the way, the amount of fun and levels of energy you will experience will far exceed the discomfort.

Semi-Private Training

Feel Good, Look Good

Get all the benefits of having a personal trainer at under half the cost by working out in small groups of 1-4 people.  Each workout is tailored to your goals and needs, and every 6-8 weeks we do a reassessment and you receive a new workout.  This allows our members to continue to make progress, and stops the boredom that can occur from doing the same stale workout each week.

This is where our members focus on their cardio and reinforce the Core Fundamental Movements.  Get your metabolism fired up with one of our instructors and our unique training equipment including: sand bags, kettlebells, sleds, battle ropes, TRX and medicine balls.

Kids Conditioning

Core Strength & Injury Prevention

Our Kids Conditioning Classes provide a safe and fun way for your video gamer to your college athlete to workout.  Our focus is on injury prevention, conditioning, building core strength and stability, and most importantly, fun!  With more kids specializing in a sport at an early age it is important to help them build the strength and stability to prevent injuries.  For the younger kids we provide a fun and challenging environment for them to learn core fundamental movements through different challenges and activities while allowing each young athlete to work at their own individual level. Exercise at a young age builds good fitness habits and can enhance cognitive function which can carry over to their school education.
For our young adult athletes, building power and strength must be achieved with an emphasis on stability and mobility. In order to prevent injury, teenage athletes have to be careful not to develop strength on top of disfunction.  Learning correct movement patterns and proper body mechanics is crucial for the sport specific athlete.
