Notes
5 x 3 on / 3 off
Felt exceptionally slow for the first one. I glanced at my watch part-way through and it read high 550s. Cranked it down and eventually ended in the low 530s. Second one decided to keep with it. Still was a struggle. Losened up for the third. The fourth one was slightly downhill. The last one was tough and uphill. But, really hammered the last min. of the workout. Finally feeling like its coming back.
