Darian Williams Momentum

Darian Williams

RTS, MAT-Jumpstart, NASM CPT

Like a fingerprint, Every body is different thus, every training program should have a foundation in this uniqueness. How one feels, looks, and performs are all byproducts in part from the demands placed on the body both physically and nutritionally. By age 3, we are all masters of our bodies, yet we somehow forget some of this mastery level knowledge as we pursue other life goals as teens and adults.

Darian has spent 20 plus yrs. studying various aspects of exercise science, bio-mechanics, 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. This knowledge provides a clear path for anyone to follow when they are ready.

If you are an individual looking to move through life more freely, a person who struggles from movement limitations caused by arthritis or another medical condition, Darian is the right fit for you. His calm demeanor and gentle approach are perfect for the aging and limited movement population.

Marquis Edwards Trainer Momentum

Marquis Edwards


Marquis graduated from the University of North Florida in 2013 with a degree in Exercise Science. He has always had a passion for being physically active. Playing baseball and basketball since the age of 4 has given him the understanding of the physical demands imposed by sport. He has an immense passion for helping young athletes achieve their goals and improve their performance through strength and agility training. One of his favorite things about training athletes is when they begin to notice performance improvement and ease and they are excited to tell him about it.

Helping others in life has always come naturally to Marquis. Training allows him to fulfill both of the aspects of life by helping others to be more physically active and healthier throughout life. When clients perform feats they never thought possible, reach their goals and are happy with the success of their training it fuels Marquis to continue to strive for better in his training career. 

When he is not training clients you can usually find him playing basketball, struggling through his own workouts, or educating himself to be better.
