So I have heard many times people saying you should keep your weight back as much as you can… and you should only begin to weight transfer after your front foot makes contact…
but judging from pictures and videos, this is not what i see:
Should Ubaldo or Brian Wilson have any weight on their back foot or leg for that matter, they would definitely break their foot, cause they are not in a proper position to take much weight. Isnt it?
So from what i see, you should have all or almost all the weight on that front leg already.
