Swim

Another entry on the quest to improve overall muscular and respiratory endurance.

2x(50 free, 50 breast, 50 fly, 50 back)
50 free in 43 seconds.

Didn't have much rest before the last 50 free, I had to get some food and get to class. I timed my second 50 free of the night, too, and it was a 42. Awful, I know.
