It's so nice to see someone else using gardening as an exercise! My doctor told me my gardening wasn't really exercise, I told him he didn't know what I meant by "gardening", and that he should come try it for a day. I lost a ton of weight, and all the gardening was DIY by myself, and it definitely helped. Plus, I had that desire to rub the doctors' comments in his face and prove him wrong. Maybe that was his intent. I didn't go back to that doctor for 2 years, and freaked him out completely at my next visit. LOL
Here's before gardening/after gardening. I was easily over 250 pounds at one time. Congratulations with your weightloss!
