RESULTS
Before & after
Why grip matters
Your grip fails before your muscles do.
Pull-ups, deadlifts, rows, climbing - the set usually ends when your hands give up, not your back. Gryprox trains the weak link directly.
Hold heavier bars longer without straps.
Each finger works on its own button.
Train the muscles that give out first.
Loosen stiff hands after hours of typing.
Made for
Lifters, climbers, players - and anyone who types all day.
Use it during your warm-up, between sets, on a call or in front of the TV. No setup, no noise, no gym needed.
How it works
Four steps. Five minutes.
Adjust each button to match your strength.
Squeeze with all five fingers, then one by one.
Short, daily sessions beat long, rare ones.
Raise the resistance as your grip gets stronger.
Gryprox vs a regular hand gripper
A spring gripper trains your whole hand at once. Your weakest finger just hides behind the others.

Before and after Gryprox
Your hands give out first
The bar slips on your last reps, you reach for straps, and your forearms are cooked before the rest of you.
Your grip keeps up
Stronger fingers, more forearm endurance, and sets that end when you decide - not your hands.

How long until I notice a difference?
It depends on your starting point and how often you train. Short daily sessions work best, so give it a few weeks of consistent use.

Yes. Each button can be adjusted, so you can start easy and increase the resistance as you get stronger.

I have a hand or wrist injury. Can I use it?
Gryprox is a fitness product, not a medical device. If you have an injury or pain, check with your doctor or physical therapist before training.
