Should you hook with vertical or horizontal fists?

[OctoberRed]

My trainer taught me horizontal hooks, but I prefer vertical

Do you switch between the two during sparring?

That's it....exactly!... listen to what your trainer tells you and then do whatever it is that you wish. …..Rockin'

I notice that when I hook off the jab I keep my palm facing down. Like a 1-3 combo I find I get it off quicker because my hand is already in that position from the jab.
But when I throw a 1-2-3 my hand will be veritical ( palm facing me) because it feels more powerful.
Is this something other people do? Or is that a bad habit I have picked up.

The further you are from your target, the more your hook will be vertical.

Proper words there....Rockin'

Inside, I really turn it over, but a long-range hook is vertical

Yeah, exactly what I thought, the mechanics of the hook just dictate it being that way

I googled this question already and on reddit it said vertical fist for inside hook and horizontal fists for long distance hook. Is this correct? Please explain why thanks

Also which on produces the most power if you are doing inside hook

I was taught exactly to do it as you say, in shorter distances you would use vertical, for longer distances the palm down one is better. Also your wrist would suffer less. You can try right now twisting your wrist as in a vertical one while moving you arm away from you, and you might see there´s more tension in your wrist muscles the farther away you have your vertical hooked fist.
