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.
