I found this on here .
Hi guys...
This might help a bit....For a few days over summer I wore a heart rate monitor to guage how many calories I used mowing lawns.
It worked out an an average of approx. 350 - 400 calories for an average lawn which took around half an hour. That was going at a good pace and using a PUSH mower!! (not one of them self propelled jobs)....Half of the energy used (i.e. 50% of say 400 cals was burnt from fat) So if you do an average of say ten jobs a day you would burn in the vicinity of 5000 calories....
Given that most adult males consume about 2500 cals per day from food (not including beer...there's probably another 10,000 cals there with me anyway) you would expect lawn mowing would be the perfect way to lose weight and get fit...
Love to know how Lawn mowing has changed your health since you started .
