TRX, TRX Bootcamp and TRX Iron

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.

TRX Iron – Get your strength training in!  A perfect mix of exercises on and off of the straps.  All levels.
