Im sorry. What I should've said is "Don't lean on your front leg when you're not punching." Only when you're throwing a right hand do you have to shift your weight onto your front leg. Otherwisewhen most of yor weight is on your front leg it's harder to move, and you're in a position to absorb most of your opponent's punching power and get hurt. Look at Mike Tyson he had a neck like a tree trunk, he had a$ good a chin but once he lost his good posture and started leaning forward any guy that could punch is able to knock him out.

Anyways on those gloves is that a padded bar that goes across? If that's the case it's intended so that you're able to make a more solid fist. It should be clenched in the middle part of your fingers.
