Learn how to use the Thera-Band FlexBar Red/Light to strengthen wrists and forearms, support rehab from tendonitis, and improve grip with simple exercises.
Quick Answer
The Thera-Band FlexBar Red/Light is a 12-inch rubber bar designed for targeted wrist and forearm exercises. Use it in three simple moves—wrist flexion, extension, and supination—to build strength and aid recovery from conditions like tennis elbow.
Why Use the FlexBar for Wrist and Forearm Work
Many grip tools isolate the fingers, but the FlexBar engages the entire forearm chain. Its ridged dry natural rubber surface gives you a secure hold even when your hands are sweaty or fatigued. Because it is flexible, you can adjust resistance by how far you bend it—no need to switch bands or weights.
Who Should Be Careful
If you have an acute wrist injury or unhealed fracture, consult a physical therapist before starting. The FlexBar is research-proven for tennis elbow rehab, but the Red/Light level is best for early-stage recovery or general conditioning—not for advanced strength work.
3-Step FlexBar Routine for Wrist and Forearm Strength
- Wrist Flexion (Palm-Up Curl): Hold one end of the FlexBar in each hand, palms facing up. Keep your forearms on your thighs or a table. Bend the bar upward by curling your wrists toward you. Slowly return to the start position. Perform 10–15 reps on each arm. Common mistake: using your biceps instead of your wrists. Keep your forearms still and only move at the wrist joint.
- Wrist Extension (Palm-Down Curl): Flip your hands so palms face down. Hold the FlexBar with both hands and bend it upward by extending your wrists backward. Lower slowly. Do 10–15 reps per arm. Checkpoint: stop if you feel sharp pain on the top of your wrist. This move targets the extensor muscles, which are often weaker than the flexors.
- Supination (Twist): Grip the FlexBar vertically with your right hand, palm facing you. Twist your wrist outward (away from your body) as if turning a doorknob. Let the bar untwist slowly. Repeat 10 times, then switch hands. Common mistake: twisting too fast and letting the bar snap back. Control the return phase for the best strengthening effect.
The Tool You Need
- Thera-Band FlexBar Red/Light: The Thera-Band FlexBar Red/Light is a 12-inch bar made from dry natural rubber with a ridged surface for enhanced grip.
