Last night I thought I'd brush up on some physics and try and solve some problems before I went to gymnastics. So I decided to try and calculate how many push ups it would take to burn off a pound of fat. I figured it would be an easy calculation because you can use the old energy equations from Newton of raising a mass E=m*g*h. And since the amount of energy is known per gram of fat, with some simple swapping of units I would be there in no time.


Well needless to say my calculation skills are a bit lacking and when I did it it came out to something like 117,000 push ups, which I was like WTF! That can't be right? Then I went to this calorie counting web-site and did some estimating on it as it has an activity calculator. I ended up coming up with about 9700 push ups which seams a little more reasonable. Then Pete came home and we started wondering about how long it would take if we just went for a walk or ran....I think the running came out to like 2.5 hours at full throttle.

So I've now started to count upto 9700 push-ups and will be monitoring it on the adjacent bar graph.
