Touch your thumb and pinky together. See the crease created at the wrist? This is where your thumb begins. Your thumb begins at your wrist. Now bend just your pinkly finger all by itself. See if you can find where it really bends from. See how it really begins down in the hand, not at the webbing of the skin. Try this with all your fingers and you will see that the fingers are all much longer and mobile than you may have thought and the palm is really no larger than a quarter or silver dollar at most. I like to think of the scene in the move “Terminator” when he pulls the skin off of his hand to reveal an extremely articulate collection of artificial bones and joints. He was soooooo mobile.
Practice moving your fingers from the correct place and you will experience consistent opening of the tissues of the hand and wrist. You’ll see your front rack position become much easier and grip strength when doing pullups or holding a barbell or kettlebell increase dramatically.
If you have questions about this, ask me when you see me at the box. I will gladly demonstrate.
