PT at work today was supposed to be ultimate Frisbee. It turned out to be too windy so they pulled out a soccer ball. After watching several players go down I decided to dismiss myself and went to the Strength Club. I didn't want to lift anything so I skipped.
Alternate the following
Skipping - 150, 110, 110 reps.
Ab Sling Knee Ups - 3 sets/15 reps
My heart rate got elevated for the entire time as I didn't take much rest between sets. Considering I haven't skipped in a while it felt pretty good.
