That's funny you mention that.. A friend here for a Month visit and I were just talking about it being really good exercise.. I try to do 4-6 hrs a day, 4-5 times a week.. I still feel it after a day of digging.. It for sure is good exercise..
Then I have a weight lifting routine I do 7 days a week..
So on the detecting days I have to force myself to do it all..
