Great idea!

42 years old, 6'1", 170 lbs.

I CrossFit (www.crossfit.com) to stay in shape. This workout regimen has me in the best shape of my life. A friend and I hiked Whitney Monday Oct. 3 and I felt as good as I did when I did it at 20 years old, perhaps better. CrossFit is a total fitness approach that combines a lot of cardio (running and rowing) with a lot of weights and olympic lifts. You can do it at a CF gym or out of your garage.

For example yesterday's workout was:
1 mile warm up run

7 rounds for time of:
30 sit ups
20 push ups
10 chest to bar pull ups
5 burpees

The day before:
1 mile warm up run

3 rounds for time of:
Run 800 meters
30 Dumbell hang squat cleans
30 burpees

Very high intensity and a lot of variety. Works great for me. Before Whitney I also did some training hikes up Mt. Baldy and in thee Cleveland National Forest.
