It's not exactly what most people would call a workout but keep in mind I live on 6 acres of land. Now most of it is used as a hay field but the other 2 acres needs a lot of TLC. Today I needed to give it some of that TLC as our lawn was starting to look like a hay field. I also needed to do some branch trimming and removal.
I spent most of my Fathers Day working outside and by the end of it, it was a workout indeed. By my calculations I burned close to 2000 calories in about 6 hours!
Total workout time: About 6 hours.
