Personal testimonial:

“These are two different people,” my mom said when she saw my before and after photos.

A year ago, I picked up tennis again after 20 years. It felt amazing—until the old pain crept back in, especially in my shoulder and arm. I’d injured my shoulder nearly 30 years ago, gone through surgery, PT, and even Egoscue, which helped me play college tennis. But the pain always lingered.

During a recent match, I met an opponent who noticed my discomfort. We talked about everything we’d tried, and he introduced me to Functional Patterns. I started training with Dennis Nel, three sessions a week, plus homework. The exercises were never painful—but incredibly effective.

I’ve learned to activate and control muscles I didn’t even know I had—my ribs, thoracic spine, and glutes. I feel taller, more balanced, and stronger. The pain in my arm is manageable now. Even walking up stairs burns in my glutes instead of my quads!

People noticed the change. A coworker saw my photos and said, “That’s not the same person!” (Then kindly reminded me I’m balding.) With Dennis’s guidance, my biomechanics are improving, and so are my results.

Now, I’m back on the court aiming for national competitions—and I’m playing multiple matches pain-free. My swing feels effortless yet more powerful. I’m even moving faster—and I’ve got the data to prove it.
