A GYM LIKE NO OTHER

Higher Standards. Higher Intensity. Better Results.

ABOUT US

Where Strength Meets Relentless Determination

At Fullsterkur Performance, we embrace the grind. Our gym isn't for everyone. It's for those who are serious about pushing their limits, who thrive in an aggressive, high-energy environment. We offer semi-private sessions, ensuring personalized attention and maximum gains. If you're ready to commit, our flagship 6 Week Challenge will test your resolve and transform your body.

Membership Limited

Unlike most gyms, we intentionally keep our membership low. This ensures that every member receives the personalized attention and coaching they need to reach their full potential. Our limited membership approach means no overcrowded classes, no waiting for equipment, and a community of like-minded individuals who are just as committed as you are.

SERVICES

WHAT WE DO

-all pricing is variable and dependent on the needs of the client-

Semi-Private Training

Semi-private training offers the best of both worlds: personalized attention and the camaraderie of a small group. With a maximum of 6 members per session, each workout is tailored to individual goals while benefiting from the motivation and energy of a team setting. This approach ensures optimal results and a supportive environment.

1-on-1 Training

1-on-1 training is available for those needing specific attention or rehabilitation beyond our semi-private sessions. While our small group training suits most, 1-on-1 sessions provide tailored, focused support for unique goals or recovery needs. This personalized approach ensures you receive the highest level of care and expertise.

Online Training

For those who can't make it to the gym, we offer comprehensive online training. You’ll receive the same high-quality nutrition coaching, accountability program, and customized workout plans as our in-person members. This is the perfect solution for those with busy or unpredictable schedules, ensuring you stay on track and achieve your fitness goals from anywhere.

He also has helped quite a bit with figuring out causes of my aches and pains as well as putting together workouts to correct them!! Alabama is lucky to have such an awesome trainer/gym!!! Caleb is the best!!!"

-Joshua Sibley

"It works! The best thing I've ever done. I lost 49lbs and I have more energy than I have had in years. I feel great. The people are great"

-Paul Williams

"Caleb knows what he is doing! His approach works! I have tried countless programs with none giving any real results. We all expect to lose weight and gain muscle instantly and that’s something you come to learn will never happen and if it does it’s not healthy. You learn you will lose a few pounds a week while gaining muscle if you’re properly eating and working out. Small losses and gains over time. I was always disappointed in anything I had ever tried so you can say I was feeling the same way especially with my injuries but what would you know it. In a week or two I actually saw progress on the scale and felt better. I think the best part was how Caleb cared for my injuries and making sure I was stretched after workouts. His understanding in that area impressed me because I have let others know this before and NOONE has ever made sure to check on me. As well as modifications to help with my injuries. If you’re looking for a full planned workout from exercises to nutrition and care then this is the place for you and Caleb is your guy."
