This morning's workout:
2:00/1:30/1:00/0:30 back-to-back intervals of jump-rope and crunches
Without breaks, this would take 10 minutes flat. I had 15 or 30 seconds between each interval, so it took a little longer. It was nice to set a goal and get all of the way through the workout. I will be working towards the same time intervals with double-under jump-rope and full-range sit-ups, but for now, I'm happy with my accomplishment.
I am feeling moderately sore just about everywhere today. Not so sore that I would think that I pushed myself too hard, just sore enough that I know the exercise is making a difference.
No ideas yet what I'll do tomorrow, may try sets of bear crawls or crab walks for duration.
