Sorry, I wasn't clear.
I'm thinking in terms of floating having broken form -- say, if I'm holding my knees to my chest and bobbing, or attempting to tread water, or in some similar position in which I'm nowhere near being in TI form.
How do I transition from such a position, in open water, to streamlined TI form?
I didn't get to the pool today. Tomorrow, I hope. I want to continue working on drills, work on form, and finding air.
Yesterday I did get a nice compliment from the lifeguard. She observed that I've been improving. And she noted approvingly that I'm working on my skills systematically, rather than just getting into the water and thrashing, as many others do. That was nice of her.
