The flu is less victorious now, and breathing getting better. Legs is OK !
In this training position on bike at both spinning and high gear was important. I rode out
up to 38 minutes, then back, the same way. This was a good training for me. Both spinning
and power work went smooth. No problem with tension in the back, even doing  most of the
time on the hooks. Felt Ok to sit in a low position and deliver the power from the hips.
