Welcome to Stretch Zone


Unlock your body’s flexibility with Stretch Zone.

Is back pain keeping you from doing what you love? 

Millions of Americans complain about back pain every single day, but why is it so prevalent? The most significant cause of back pain in adults comes from posture and how much time you spend sitting. Even if you stay active, the average person sits almost twice as much as twenty or thirty years ago. 

The human body was made to be in motion. Commuting to work, sitting at your desk, eating meals, enjoying leisure time on the couch — these actions add up. But how can you manage these aches and pains? By visiting us at Stretch Zone in SouthGlenn! Instead of manipulating your body in unnatural ways, our proprietary method relies on targeting your nervous system to make lasting gains in your mobility. 

You will see results immediately from your first session. The longer you keep up with the program, the more likely you will see a lasting impact that carries over to every aspect of your life. Don’t miss out on another walk with your children because you’re too sore from the day and don’t turn down that extra round of golf with everyone from the office. The first stretch is on us!

Hours of Operation



The Stretch Zone Method® addresses flexibility from a neurological perspective. This is achieved by dealing with the muscle’s nervous tension (“tonus”) to reach an optimal active range of motion. The goal is not to make a person more “flexible” or “elastic,” but rather enable you to move more functionally by re-establishing a more ideal resting muscle tone. By re-educating the associated nerve-muscle reflex, the Stretch Zone Method® leads to movement becoming easier and more efficient.

Rather than creating soreness by pulling on our limbs to extremes, the Stretch Zone Method® works through the nervous system to achieve lasting gains in flexibility and range of motion. The method rests on the notion that changing and re-educating our muscle’s nervous energy is a major factor in unleashing our body’s intended function. This nervous energy, known as the stretch reflex, is our body’s automatic defense against the dangers of over-stretching. Any movement that goes too fast or too far, or is held for too long, will cause your body to resist with the stretch reflex. Once the reflex is activated, your body has effectively said “no more” and resists the stretch. Any further attempt at stretching becomes counter productive and may even cause long term damage.
