2,000yds in the pool, good swim. Had the lane to myself!

Average HR 129 for 55 minutes. I want to increase the percentage of flip turns I do. Now I mostly do touch-turns. I get gassed by flip turns, and I can only do 4 of them in a row (100yds), several times in a session. Something to work on next year because I anticipate the end of swim season soon, transitioning to cycling.

2k yds, good swim. 117avg HR. Empty lane.

Flip turns for the first 100yds of each 400yd set. Next season I will try to achieve all flip turns.

Also experimenting with explosive breathing vs continuous breathing as I have done in the past. The theory is with explosive breathing I hold the breath allowing air more residence time for more O2 to diffuse in the lungs, compared with continuous exhalation (similar to normal breathing) where the O2 starts to exit the lungs immediately.
