TheraBand FlexBar Exercise Bar – 12" | 4 Resistance Levels | Tennis Elbow Relief | Grip & Forearm Strengthening

Research-proven grip strength and elbow pain relief — no equipment setup required. The TheraBand FlexBar is a clinically researched resistance device designed to strengthen the grip, stabilize the upper extremity, and treat conditions like Tennis Elbow (lateral epicondylitis) without injections or expensive equipment. Made from durable dry natural rubber with a ridged surface for a secure hold, the FlexBar is used through bending, twisting, and oscillation movements that target the forearm, wrist, and hand muscles. At 12" long, it is compact enough to use at home, in the clinic, or on the go. Available in four progressive resistance levels.

Frequently Asked Questions

How does the FlexBar help with Tennis Elbow?
The TheraBand FlexBar is the device used in the Tyler Twist exercise protocol, a research-proven technique for treating lateral epicondylitis (Tennis Elbow). The Tyler Twist involves gripping the FlexBar with both hands, twisting it with the unaffected hand, and then slowly untwisting it using the affected forearm — an eccentric loading exercise that has been shown in clinical studies to significantly reduce Tennis Elbow pain and improve function. The ridged surface and flexible rubber construction of the FlexBar are specifically designed to facilitate this twisting motion safely and effectively.

Which resistance level should I start with?
Most people with Tennis Elbow or forearm pain begin with Red (Medium) resistance. Yellow (Light) is appropriate for patients in early post-injury rehabilitation, those with significant pain, or users with limited grip strength. Green (Heavy) and Blue (Extra Heavy) are for users who have progressed through lighter levels or who are training for athletic performance. Always follow your physical therapist’s or occupational therapist’s guidance on the appropriate starting resistance for your specific condition and strength level.

What exercises can I do with the FlexBar?
The FlexBar supports three primary movement types: bending (flexion and extension of the wrist and forearm), twisting (rotation exercises including the Tyler Twist for Tennis Elbow), and oscillation (rapid shaking movements that activate stabilizing muscles throughout the forearm, wrist, and shoulder). These movements can be combined into a comprehensive upper extremity exercise program. TheraBand provides exercise guides and video resources for FlexBar use — consult your therapist for a program tailored to your specific rehabilitation or performance goals.

Is the FlexBar latex-free?
The TheraBand FlexBar is made from dry natural rubber, which is a different formulation from the latex used in TheraBand resistance bands. Dry natural rubber has a significantly lower latex protein content than standard latex products and is generally considered safe for most users. However, individuals with severe latex allergies should consult their physician before use, as trace latex proteins may still be present. If you have a confirmed latex allergy, discuss alternatives with your healthcare provider before purchasing.
