Good idea! You know, that thought had crossed my mind once and I meant to buy some. I don't know what happened but I totally forgot (my mind is on too many things!). Thanks for reminding me! I'll look for some hand/ankle weights when I'm out this weekend and add that to my walks. BTW, I do carry a 20-25 lb backpack when I walk -- does that count too? I guess even if it does count my body may be used to it so I'm going to have to step it up with something else regardless.
