Take your hand face it palmwards
Punch it as hard as you can, ouch, you get a sharp pain in your fist and your palm
Now get your hand turn it into a backhander, let your muscle loose in your hand and slap our palm, kinda like a lazy slap. POWAH
Thats called deadweighting, tis martail arts skill but it works, saw it on BBC3
