How do you use the legs on a basic boxing uppercut

[BillyNoMates]

Do you drive with the legs in the direction of the uppercut ie up

Or is the uppercut purely from the rotation of the body and nothing else/

[BG_Knocc_Out]

Theoretically, you can utilize both. I can see using your legs while on the inside, head to head, depending on the room you're given you might be smothered for rotation.

But, 90% of the time I think rotation is the best way. The ability to apply centripetal force is only obtainable by rotation.

Freddie Roach teaches to throw uppercuts through the back.
