Because your hands are directly connected to your brain and nervous system through a huge network of sensory nerves.
When you improve grip strength, you’re not just strengthening your forearms, you’re also strengthening how your nervous system communicates with the rest of your body.
Here’s what’s actually happening:
1. Your hands send constant signals to your brain
Your fingertips, palms, and forearms are packed with sensory receptors.
When you challenge your grip (like in dead hangs), you activate these receptors, this boosts nervous system activity and improves how your brain processes movement, tension, and stress.
2. Strong grip = better neuromuscular control
Your grip strength reflects how well your brain controls your muscles.
If your grip is weak, the brain body connection is weaker.
If your grip is strong, the connection is sharper.
This is why grip strength is linked to:
• Better coordination
• Better balance
• Better reaction time
• Better overall strength
3. Strong grip supports your stress response
When grip strength improves, your body becomes better at handling load and tension.
This reduces the fight or flight response and supports a calmer, more regulated nervous system.
4. Grip strength and longevity
Studies show grip strength is one of the strongest predictors of overall health as you age because it reflects nervous system resilience and muscular function together.
So your grip isn’t just a muscle, it’s a window into your nervous system, your strength, and your overall health.
If this is something you want to work on, start adding dead hangs, farmer carries, or even simple squeezing drills into your week.
Your nervous system will thank you.
