Embarrassingly, I couldn't deep water start this year! It felt like I just didn't have the strength to keep hold of the handle, I tried my double boot first, failed, switched to a RTP, still couldn't hang on. In the end I had to prove that I could do it and had to go up on a handle on the boom.
So, assuming my technique is probably OK but a little rusty. What off season training would be good to prep for next year?
