Has anyone added any specific exercises or created any routines to improve this area of winging?
Power up the wing and let it lift you up instead of relying on the leg muscles.
I find doing it this way is much easier so let the wind helps you .
Yes if you mean like training routine
I sit on the floor on my knees like in the bug start and sit up whilst holding a balance ball over my head - I do this until my stomach and thighs start to burn
I watch tv whilst kneeling, standing on one foot/both feet on a wobble cushion. The cushion is good for general balance and for strengthening the ankles
I also watch tv standing on a football like the rodeo guys do for rodeo training
is that what you meant?
You can waterstart without the kneeling phase, by putting your feets straight away on the deck as a slow prone take off, and staying low while grabbing the wing then standing tall as soon as a gust hits. Works on any volune board with a bit of training on balancing. It's much (much) faster, more efficient and reliable method as you remove one step, can handle more choppy sea and irregular wind. Most pros I've seen do that. Kneeling might feel easier at first but is an inferior method long term i think.

Not sure i understand you "slow prone takeoff" method ?
You take off on the board and crouch low. Grab the wing, and stand up as soon as a gust hits.
Its like the sinker board method in that video :
This is my go-to exercise for core and balance training...
