In this powerful episode of the Bold Inventor Show, host J.D. Houvener and trademark co-host Matt Kulseth welcome Aaron Walker, the tenacious inventor and founder of Twist Resist—a revolutionary strength training device developed specifically for physical therapy and rehabilitation.
Aaron’s journey is anything but ordinary. From repeated dirt bike injuries to building prototypes in a mobile gym inside a box truck, Aaron shares how twists of fate—both literal and physical—led him to develop a machine that mimics circular, joint-specific strength movements rarely addressed in traditional PT or gym equipment.
💡 In this episode, you’ll learn:
🌀 What makes Twist Resist unique
Rotational strength and circular resistance aren’t just buzzwords. Aaron walks us through why linear bands and cables don’t cut it—and how his device better replicates real human motion.
🛠️ The decade-long invention journey
From garage prototypes to university-supported research and PhD feedback, hear how Aaron evolved his device from a sketch to a functional machine now being beta tested across PT clinics.
⚙️ Bootstrapping a hardware startup
With no outside funding and 10 machines now completed, Aaron explains the real cost of building a medtech hardware company from the ground up.
📈 Business model crossroads
Should Twist Resist license to a big brand, go D2C, or pursue fitness studio integration? Aaron shares his current strategy—and how he’s developing protocols for therapists to use his machines effectively.
🧪 Validated by science
A University of Southern California study found Twist Resist to be up to 40% more effective at muscle activation than traditional resistance methods like cables and bands.
🔐 Protecting the IP
Twist Resist is protected under a comprehensive U.S. utility patent. JD breaks down what it covers, and how Aaron used early filing to build confidence during development.
💬 Real talk on pain, perseverance, and patenting
Aaron’s honest advice to other inventors? It’s not fun, it’s expensive, and the sacrifices are real—but the impact is worth it.
If you're in physical therapy, sports rehab, personal training, or product design for medical and fitness tech, this is a can't-miss interview. Aaron’s story proves that even solo inventors can develop life-changing tools when passion meets persistence.
