Most people don’t think about their spine until it starts making decisions for them. Dallas has spent over fifteen years making sure that never happens to the people he trains.

Dallas is a certified flexibility physiologist through Stretch Therapy, which is a fancy way of saying he’s spent a career figuring out exactly why bodies hurt and exactly what to do about it. Not general stretching. Not “foam roll it and see.” Real, targeted work on the muscle chains that pull your spine out of alignment in the first place.

Here’s the thing most training programs get wrong. They chase strength and mobility as if they’re two separate conversations. Dallas doesn’t see it that way. He sees a body that’s either stabilized correctly at the spine or isn’t, and once it is, everything else, the swing, the golf shot, the tennis serve, the simple act of getting out of bed without wincing, gets easier. His entire method is built around identifying which specific muscle imbalances are dragging your spine angle out of position, then fixing them through targeted stretching and stabilization work instead of guessing.

Dallas is also Carson’s brother, and the family resemblance shows up less in appearance and more in standards. Where Carson built MotionLab’s strength and conditioning side around Tour-level precision, Dallas holds the manual therapy side to the same bar. Growing up around the same relentless attention to detail, it’s no surprise the two of them ended up running complementary sides of the same operation, one making sure the body can produce force, the other making sure it’s actually free enough to use it.

Dallas has worked with people across the full spectrum, from weekend warriors to professional athletes, and the through-line in all of it is pain relief that actually holds up. A lot of manual therapy gives you twenty minutes of relief and sends you home to undo it with the same bad patterns. Dallas builds his sessions so the fix sticks, because he’s not interested in seeing you back in the same spot next month with the same complaint.

At MotionLab, Dallas runs Assisted Stretching, a PNF-based approach that goes well beyond what you’d get from a generic stretch class or a foam roller at home. PNF work uses your own muscle contractions against light resistance to unlock range of motion your body has been protecting for years, often without you realizing it. For MotionLab’s members, many of whom are golfers and pickleball players in their 40s, 50s, and 60s, that unlocked range of motion is often the single biggest lever available. You can add strength all day, but if your hips can’t rotate or your thoracic spine won’t extend, you’re capping your own ceiling.

Dallas treats spinal health as the foundation everything else gets built on, not an afterthought you handle once something already hurts. That’s a mindset shift for a lot of MotionLab members who grew up thinking of stretching as the five minutes you skip before a workout. Dallas’s sessions aren’t a warmup. They’re programmed, progressive, and specific to what your body is actually doing wrong, which is why members book them as a standing part of their training, not a once-in-a-while indulgence.

What makes Dallas particularly valuable inside MotionLab’s model is how well his work pairs with the strength and conditioning side of the house. A golfer can be doing everything right in a T-Time class, building rotational power and progressive strength, but if nobody’s addressing the muscle imbalances limiting that same rotation, progress stalls. Dallas is the piece that keeps the whole system honest. He’s not trying to replace your strength work. He’s making sure your body is actually capable of using it.

Ask any longtime MotionLab member what changed their game and you’ll hear plenty of answers about strength gains and swing speed. Ask what changed their daily life, the ability to get up from the couch without a grimace, to play eighteen holes without their lower back locking up on the back nine, and Dallas’s name comes up just as often. That’s the kind of win that doesn’t show up in a highlight reel but shows up in every single day you’re not thinking about your body because it’s just working the way it’s supposed to.

Dallas’s philosophy is simple to say and hard to execute well: prioritize the spine, address the actual imbalance instead of the symptom, and build a body that can keep playing the sports you love for decades instead of years. Most people don’t get access to this level of individualized manual work unless they’re a professional athlete with a team doctor on staff. At MotionLab, it’s built into the model from day one.
