My open water course included drownproofing (four different techniques, in fact, with the diver wearing nothing but a bathing suit) as an important component.
Here's a list of the "drownproofing" skills required in my open water course:
1. Tread water (swim suit only) for 15 minutes, hands and wrists held out of the water, mouth and nose cannot submerge.
2. Float on one's back (swim suit only) for 15 minutes, mouth and nose cannot submerge.
3. Perform the Lanoue drownproofing technique (swim suit only) for 15 minutes, cannot touch bottom of pool.
4. Perform the Lanoue without arms (swim suit only) for 15 minutes, cannot touch bottom of pool.
5. Perform the "mafia float" drownproofing technique (swim suit only). With this technique, one holds one hand/wrist with the other hand, hands behind the back. And one crosses one's legs at the ankle. So, the diver cannot release his hand/wrist, cannot uncross his ankles, and cannot touch the bottom of the pool.
Each of these techniques was performed in the diving well of the university natatorium, TA's circling to gently push students away from each other as they inevitably bumped against one another.
I might be recalling the times wrong; they might have been 10-minute periods, rather than 15. But, I'm almost certain they were 15-minute periods. I recall being in the diving well a *long* time when we were tested, as we went from one skill to the other without a break.
You can't possibly appreciate what successfully passing this skill did for the confidence of this scuba student, who possessed only marginal, barely passable swimming skills when I began my open water course.
Of course, I might be imagining all or part of this...
Safe Diving.

Turns out I can float in fresh water (swimming pool) BUT I have to make like a starfish with my arms and have full lungs--so breath from the top of the lungs. My biggest obstacle was the whole full lungs thing.Empty lungs and I still sink.
Frosty,
Starfish is a great description! As for me, having long and very heavy legs, I had to learn to fill out my entire lungs, especially the *bottom* of my lungs. "Pooch out your gut!" my scuba instructor would yell at me. It was a painful ordeal, all of this pooching and all of this stretching of my arms *way* out from my head. But painful though it was, you had to remain relaxed; you couldn't tense up. I was 31 years old in 1986 when I took my open water course, and I was still very lean, and my build was not the least bit slight. I was a sinker like nobody's business. When I finally managed a successful back float, you couldn't have found anyone more surprised and elated than I, myself, was. An incredible confidence building experience!
Safe Diving,
