Swim, Bike, Push-ups, Sit-ups

Swam in the lake a bunch with Emily early in the am.  She was practicing her strokes for swim team.
Then completed:
25 Push-ups
100 crunches
25 Push-ups
100 penguins
25 Push-ups
50 Sit-ups with a twist
25 Push-ups

Not sure what I did other than the swimming but my left shoulder is killing me.
