This is the man to which I've learned everything about boxing from the start. He's extremely concise and thorough. He's also Britain's own! His name is Fran Sands, I've had the distinct pleasure of speaking to him personally, great great man, couldn't be a better example of a humble and helpful coach.

He has three videos on the left hook: Short, mid, and long ranged. All very helpful, here's the short ranged left hook to start you off.
