Say goodbye to the guilt, the guesswork, and the cycle of starting over — and say hello to group training with structure, support, and real, lasting results.

WHAT WE DO

At GTA Fitness, group training is what we do best.

Every class follows our signature 4-Core™ Method — a strategic 4-week cycle that rotates between lifting, cardio, endurance, and recovery. It keeps your workouts exciting, your results building, and your progress on track — without the burnout or guesswork.

Train Smarter. Recover Stronger. Repeat.

The workout system your body actually needs.

WHY IT WORKS

Most people fall off because their workouts are too random, too intense, too boring — or they just don’t know what to do. The 4-Core™ Method fixes that by giving your body what it actually needs week after week.

Built-in balance — You cycle through strength, cardio, endurance, and recovery, so you’re always progressing without overtraining.

No burnout — Recovery isn’t a pause — it’s part of the plan. You’ll build muscle, stay locked in, and come back stronger every week.

Progress with purpose — The rotation is intentional. Each week builds on the last to improve strength, stamina, and consistency over time.

You’ll actually stick with it —It’s easier to stick with it — because you’re surrounded by a community working toward the same goals as you.

DON'T TAKE OUR WORD FOR IT...

What people are saying about GTA...

GTA Fitness & Performance is a more than just a gym it’s like family. Everyone pushes each other to do and be better all the time. Coach Jon is great at motivating, giving great advice, and providing a space where people feel comfortable, seen, heard and not overlooked.

Shankuria S.

This is arguably one of the best gyms and workout environments in NC!! The training is challenging yet rewarding. But, the most unique component of GTA, is the family culture that everyone experiences when they join the gym. Coach Jon has curated a fun an accepting atmosphere that motivates you to be better every single day!

Erika B.

GTA has been the best place for me and my workout journey! I absolutely love being a member of GTA not only do you get a great workout you make some great relationships while doing so. When you come you have no other choice but to want to come back Coach Jon stays on you and pushes you and the other members are always there too!

Jakala W.

...He makes sure I am educated in nutrition and how to maximize effectiveness of a workout! I have a back injury that Jon is aware of, he is attentive to help reduce the risk of additional injury and to help strengthen the muscles in that area! I feel safe here. The attention to detail makes a difference! Everyone I have come in contact with at GTA has been amazing!..

Christina C.

GTA is a great gym to join and has members that make you feel welcome, secure and motivates you to do your best... The GTA gym family is truly amazing! Now let's talk about Coach. Our trainer Jon is theeee best. He knows working out is more than physical and promotes our mental health as well. He offers nutritional guidance, checks in when we are "missing" lol

Alana W.

I started GTA by visiting a bandz class and it didn’t take long after for me to commit to being a full time member. Jon’s encouragement, drive and exuberance pushed me to stay consistent and committed to reaching my body goals. Thanks to him, I not only have become stronger physically but mentally as well. If you’re thinking of purchasing a membership with him, do it now!
