Floating and breathing.

Did some floating/breathing experiment. Floating in streamlined position and slowly breathing in and out.
When breathing out he legs sunk a bit more than the front and when breathing in the legs clearly rose up and even bobbed up braking the surface. Could be repeated endlessly. Legs raising speed reacts strongly on sucking the air to the belly.
Didnt had to raise the arms above water to achieve this. Front or back float. same story.
Cant speak for others, but in my case, more air=better balance.
Balance dimensions
- inseam 80 cm
- standing on flat feet in streamlined upperbody posture, floor to fingertips 233cm
- ape index + 3.5 inch

I've not been able to do belly breathing in the pool despite using it when running.

Dont think I use it much during normal swimming either.Too much going on to notice, and also to much core tension. (to much?) In one arm swimming there has to be enough time to add more of it.
The effect on balance is undeniable. Another swim challenge to try to use it in normal (relaxed)swimming
