Our Approach – Relationship-based Fitness Training

Camaraderie. Guts. Fun. Tenacity. Zest.

At the Fort our recipe is simple. Relationship-based fitness training… working shoulder to shoulder with beginners to marathoners, all inching closer to becoming healthier and stronger… that’s motivation.  Every time you exercise with us, you have a Coach. Our fitness professionals always offer proper form, motivation, what we are working and why we are working it!

The results are life changing and powerful. We partner with you in your quest for a fit healthy lifestyle. We know you, your goals, and your limitations. The environment is challenging yet our approach is no one left behind – an amazing balance that works for all! Lisa and Danielle together offer 56 years collective experience of motivation, camaraderie, respect and FUN. Along with their staff of 38, The Fort is a place where everyone feels welcome and accepted.

Our facility is built on our philosophy. No wandering off into a sea of treadmills here! We provide an amazing variety of activities led by an upbeat, experienced staff in a clean and inviting 13,000 square foot gym.

Fortitude Health and Training’s business model is four-pronged:

GROUP CLASSES, where hundreds get in and stay in top shape by attending any of The Fort’s 39 fun classes per week. We offer Bootcamp, TRX Suspension Training, Barre, Kickboxing, FMX Heart Rate Monitoring, and Iron Strength Training classes.  At Fortitude you get an amazing variety that cannot be matched at the smaller boutique gyms; you’ll never be bored, you’ll always be safe. Every time you workout you get a Coach showing all levels modifications and delivering a spot on full body class. All for a fraction of the price of our competitors. At The Fort our mantra is YOU SHOW UP – WE TAKE CARE OF THE REST!

SMALL GROUP TRAINING – At The Fort, Small Group Training is a great marriage of the individual attention and customized programming of Personal Training along with the economic sensibility of our Group Training. After you complete our extensive Personal Training questionnaire your Coach will craft a well-thought, and professional program tailored to meet your goals! Then you’re off and running! Your six-week program will meet twice per week for one hour and you’ll work alongside three other like-minded, goal-oriented people. At The Fort, there’s a Small Group structure perfect for you!

PERSONAL TRAINING – Fortitude has a breadth of experienced and certified personal trainers, partnering you with a Coach who will bring you creative, ever changing, thoughtful and totally personalized programming. Even clients who grudgingly start an exercise program find they love it and look forward to each session!  Fortitude’s award winning Personal Training Program delivers 130 training sessions per week and we are waiting to meet YOU!

CORPORATE WELLNESS PROGRAM – Fortitude’s group based and personal training model is complemented by a cutting edge Corporate Wellness Program. As New Hampshire’s premier Corporate Wellness Provider, we know and businesses understand that a healthy staff member is more productive, has fewer sick days and is more committed to the organization for which they work.
