In golf posture, swing your right hand just like you were going to toss a ball underhanded to your target.

basically a right handed 'slap'

Now make that exact same motion, but freeze the angle in your right wrist, and direct force 'down' in front of the ball until your right arm is straight

eventually you can learn to 'allow' the right wrist to 'flow', but until you 'know' the feeling of keeping it bent back and hitting 'crisp' shots, keep it frozen, like it is in a cast, and focus on the right forearm underhanded 'toss' motion, slap that inside back corner with a frozen right wrist
