The Extensor

🔹 Rubber Hand Extensor Exerciser – Build Bulletproof Fingers & Forearms

Most people only train their grip. But real strength? That comes from balance.

The Rubber Hand Extensor Exerciser targets the extensor muscles — the often-neglected muscles on the back of your hand and forearm that control finger extension, wrist stabilization, and grip endurance.

Whether you're an athlete, musician, climber, or just want to fix your desk-job wrist pain, this simple tool unlocks powerful benefits with just minutes a day.

✅ Features & Benefits:

• Train the Opposite of Gripping – Strengthens your finger extensors to balance out grip training and reduce injury risk
• Rehab & Prevent Pain – Ideal for treating tennis elbow, carpal tunnel, and repetitive strain injuries
• Boost Performance – Improves hand speed, finger control, and grip stamina for climbers, fighters, gamers, and lifters
• Compact & Portable – Toss it in your pocket and train anywhere
• Multiple Resistance Levels – Stack them or progress over time

🔧 How It Works:

Slide your fingers into the loops and push outward to fight the resistance. Just like a grip trainer strengthens your flexors, this tool builds the antagonist muscles
