Question

When your a running back in football do you run on your toes and do you pump your arms with the fooball?

Answer 1

yes, toes for quickness, but to generate power you need to land on your whole foot

Answer 2

yes and yes

Answer 3

it depends on where you are in the open field you'll run faster on your toes and pumping your arms but usually if your going through traffic you'll kind want to plant off your whole foot to cut and stuff and you'll want the ball high and tight against your body so your arm won't move as much
