30-Day Exercise Challenge - Day 4
December 4, 2008I’m still getting used to exercising with a heart rate monitor(HRM) but I think it was a good purchase because I find myself drifting off during the running and the bicycling after a while and the HRM starts beeping at me when I’m not pushing myself enough. The downside of using an HRM is that instead of it getting easier the more you exercise you simply keep pushing yourselt harder to keep yourself within your target range.
- crunches : (25 x 4)
- leglifts : (20×4)
- 3-mile run : (35m27s/588kcal)
