I've noticed some asymmetrical tensions and pains in my back that I would have assumed would just go away with time, but they haven't. It's never been an issue for me with prone surfing, but maybe it's just easier to hurt yourself with that paddle. I suppose the asymmetry makes some sense with the sidewise stance sprinting. On average I manage to get out and SUP surf maybe 2-3 times a week.

Have any of you found a stretching routine that's made a real difference for you?

Cheers
