Personal training is the most progressive form of training. It may be scheduled with you as a one on one session, or you may train with a buddy*. Your trainer will be with you for the full session and your program will be specifically tailored to fit your goals and your needs. We take into account medical conditions, previous injuries, lifestyle, athletic demands, and everything needed to make a truly specific program to help you accomplish your goals as safely and effectively as possible. We measure our success by your success. Private training may be supplemented with our group training for added results!

*Buddy training rates are higher than one on one training. For more information on pricing, CONTACT US.

Group Training 

Group training programs are still specific to the individual's needs, just implemented in a group setting, so the cost is less per session. For group training, you must reserve your space in advance. All times outside the schedule below are for private training and buddy training. If you would like to create a new group, contact us to schedule times. A minimum of 4 participants are required.

In order to participate in group training, you must complete an initial consultation & movement screening.



Our trainers are well educated, highly skilled and experienced. We are invested in you and take pride in the success of our clients. We all have our specialties and work as a team to ensure you get the most out of your experience with Momentum.

Darian Williams Momentum

Darian Williams

RTS, NASM CPT, MAT Jumpstart

Like a fingerprint, Every-Body is different. Therefore, every training program should have a foundation in this uniqueness. How you feel, look, and perform are all byproducts, in part, from the demands placed both physically and nutritionally on the body. However, we are masters of our bodies by age 3. Yet somehow we forget this mastery level knowledge as we pursue other life goals as teens and adults. Darian has spent over 20 years studying various aspects of exercise science, biomechanics, engineering and physics to help people reconnect and reclaim their bodies in order to achieve their true goals. With a specific background in joint mechanics, Darian has come to understand that there is an order of operation to exercise that applies to all ages and both genders. His knowledge provides a clear path for you to follow when you are ready. His experience shows through his training practice and he is passionate about helping people.

kelsey beckmann dietitian

Kelsey Beckmann


Kelsey Beckmann is a registered dietitian and local runner from
Jacksonville. Her interest in dietetics was sparked by her own experiences of the impact of nutrition on the human body in motion. Kelsey grew up playing competitive soccer, and eventually ended her career as a D1 soccer player to transform into a distance runner. Since then, she has enjoyed several opportunities to race at the top level of running across the United States. As both a soccer player and a runner, she has felt the ebbs and flows of nutrition on performance. Kelsey knew she was destined to help other athletes benefit from the implementation of optimal nutrition. When Kelsey is not working with ambitious athletes, she works as a clinical dietitian in acute care and short term rehabilitation. She enjoys the challenges that both arenas bring, and looks forward to developing herself as a well rounded registered dietitian. Kelsey is grateful for the opportunity to promote healthy and active lifestyles within the Jacksonville community.
