Hey all,
Have been having issues with tennis elbow / kiting elbow - most probably from long downwind surfing runs from Swanny to Brighton. I'm a natural footer, riding the waves backhand most of the time. Every bottom turn is a big pull with my left arm on the kite. Experiencing plenty of pain in the elbow. Have rested it for a while now, no pain at the moment, and looking for advice on exercise regime to prevent it coming back.
Cheers :)

just hold you bar differently- with palm underneath the bar, instead of palm on top of the bar.

I had same issues. The best cure was ... water! Try to drink 4-5L of water a day for about one week. Your body need water, kite elbow = dry mucles.

Other tips:
Rest
warm up before a session
Strech (lift your 4 fingers with your other hand)

I had a sore elbow from kiting, I ignored it for a few weeks until I was at the physion for a sore knee. The physio had a poke and a prod, worked out it was a strain and not 'tennis elbow'. He ended up strapping it almost straight and so I was unable to bend it even if I wanted to. Five days with the strapping and a few extra days without kiting and it worked a treat.
