Group Training and Fitness Classes Videos

Fortitude Health and Training’s Co-Owners, Lisa and Danielle, have been leading folks to become in amazing shape for over 25 years via their kicking group training and fitness classes! Along with their staff, Lisa and Danielle have inspired thousands – and once you get under their wing, you’ll never want to turn back.

The recipe is simple – its the power of many. Relationship-based training… beginners to marathon runners working shoulder to shoulder in an inclusive, supportive “no one left behind” environment. Sure, it’s challenging, but challenge brings change. And, with our modifications and encouragement, each member walks out the door each time thinking, “I nailed it today.”

The Fort offers 38 classes/week: Kickboxing, TRX Suspension Training, BootCamp, Barre, Iron Strength Training, and more. There’s a time and a class for everyone! You can do it!

TRX & TRX Bootcamp

If you tired of hitting up the same machines, day-in & day-out, TRX Suspension Training may just be thing to get you out of a rut. TRX (Total Resistance eXercise) was developed by Navy SEALs while on deployment, when they had little access to gym equipment. Using suspension straps and bodyweight exercises, TRX helps develop strength, balance, flexibility, and core stability.

Fortitude Health & Training uses the TRX Suspension Trainer to help leverage gravity and body weight to do hundreds of different movements. No class is ever the same! The beauty of doing suspension training with TRX is the simplicity: users can easily adjust their position to make an exercise easier or more difficult. With this type of flexibility, and the ability to move quickly between different movements, your trainers at The Fort will have your heart beating and your muscles working all class long.

As an added bonus, almost every exercise involves your core! Multi tasking at it’s best… work your biceps, triceps, chest and back while working your core. Join us today for TRX – it’s perfect for all levels. Make your body your machine!

TRX – Total-Body Resistance Exercise with a Suspension trainer. Innovative functional training that develops strength, balance flexibility and core stability simultaneously. Suspension straps use body weight for a complete workout and help to build a rock solid core. Perfect for all levels!

TRX Bootcamp – A fun, high energy combination of strength training on the TRX straps along with the cardio/strength benefits of Bootcamp! We pull out the Bootcamp toys to give you an awesome workout – it’s the best of both worlds! All levels.

Combat KickBox

Kickboxing blends athletic drills with martial arts to create an intense cardiovascular workout. Uses gloves and bags to pack a powerful fitness punch. Huge calorie burn. All levels.


Challenge yourself beyond traditional strength training with this total body, functional strength training class. We will challenge your muscular endurance as well as your balance and coordination by moving through all planes of motion with multi-joint and compound exercises. All levels.


Barre is an exciting workout inspired by ballet, yoga and Pilates. Set to fun, upbeat music, Barre is a total body, no impact workout accessible for ALL levels of fitness. We are so excited to bring this new phenomenon to The Fort!
