What if one of the strongest predictors of your overall health, functional longevity, and physical capability is hiding in the palm of your hand? In this eye-opening episode of The Anthony Amen Show (formerly Health & Fitness Redefined), sports chiropractor Dr. Terry Zachary joins us to reveal the overlooked world of hand health and why grip strength is far more than a fitness metric — it’s a window into your long-term well-being.

Dr. Zachary breaks down the science behind grip strength and longevity, sharing how research links stronger hands to better mobility, lower all-cause mortality, improved nervous system function, and even better cardiovascular health. At Redefine Fitness in Stony Brook and Mount Sinai, NY, we see it every day:
when your grip improves, so does your overall strength, confidence, and independence.

We dive deep into one of today’s most widespread issues — carpal tunnel syndrome. Dr. Zachary explains:

• The anatomy behind wrist and hand pain
• Early symptoms people often ignore
• Why repetitive strain destroys hand balance
• How to maintain proper muscle activation
• The best everyday habits to avoid carpal tunnel altogether

Whether you’re a programmer, pianist, gamer, guitarist, lifter, or anyone glued to a keyboard, you’ll learn practical ergonomics that protect your joints, increase performance, and reduce inflammation long before injury sets in.

We then explore the most common grip-related injuries, including cycling-related nerve compression (“biking syndrome”), overuse from heavy lifting, and the slow breakdown caused by poor posture. Dr. Zachary highlights how the body adapts — often negatively — to the physical shortcuts we use every day and how restoring balanced grip patterns can dramatically improve pain, strength, and range of motion.

Of course, we settle an age-old debate: to crack your knuckles or not?
The answer might surprise you.

This episode arms you with practical tools to strengthen your hands, protect your wrists, improve your lifts, boost longevity, and rethink how much your grip influences your entire body.

Tune in, learn, and take control of your hand health — because a stronger grip often leads to a stronger life.
