About
Meet Shuntunna Henry, founder of S-Flex Fitness.
S-Flex started in a garage with a handful of clients who kept showing up. It's grown into a private studio in Grand Prairie — same model, same standard. One trainer. One client at a time. Real work.
AI-generatedThe story
Shuntunna grew up active at the South Dekalb YMCA in Decatur, Georgia — racquetball, basketball, swimming, weight training. Helping people overcome obstacles through fitness got embedded early.
He earned a B.A. in Health Science from the University of Arkansas at Little Rock in 2012, then trained students, family, and himself before going all in on coaching. He earned his personal training certification through ISSA, and went on to add Fitness Nutrition and Strength & Conditioning Level II.
Along the way he coached at Anytime Fitness, an independent strength gym in Tampa, Lifetime Fitness in Mansfield, Fitness Connection, and Orange Theory in Mansfield — learning what worked, what didn't, and what he wanted his own place to feel like.
S-Flex Fitness is the result. A private space in Grand Prairie built on a simple idea: every client deserves real attention and a plan that actually fits them.
Train with Shuntunna.
First session is a conversation, a movement screen, and a real workout. From there, we build.
