Is the idea for the front foot to push the board down the face of the wave before you plant the rear foot, or is their some other benefit Im missing?
Another technique I see promoted by these coaches is the hands flat on the board for the pop up instead of pushing from the rails.
I am not sure, my instructor did not say, but he was very definite about getting us to pop up that way and I took the approach of just doing what he was telling me. And sorry made a mess of describing it. Edited above. The hands are staying on the deck until both feet planted so that's keeping the front down I think.
This explanation seems to indicate less likely to make a mess of getting to the feet.
I have seen some video of Alex Knost on a mid length in Mexico I think, using the old explosive pop to both feet at the same time. So not all elite surfers will use the front first method.
This video is satire, but that pop up at 1:21 is so smooth that he must be doing the front foot first method (on a mid length of sorts) and I have definitely seen some really good longboar riders on instagram do a really smooth front foot first stand up. So its not a shortboar only thing.
I should say that despite my lessons I am still rubbish at surfing and I got the soloshot video to prove it
My teacher did succeed in sorting my pop up though and I feel the benefits in terms of being in more control. Agree with not grabbing the rails, fingers drag in the water and hands flat means more distance between chest and deck to get that front foot planted - this was explained to me by an amateur competitive surfer a long time ago
