Weighted vest makes a HUGE difference in my daily walks! This is the one my husband and I both use. You can add or take out weights from 11-20 pounds! I like how it has the weights on both sides vs just the back because it's more evenly distributed. Plus I have lower back problems and this doesn't bother my back at all. Add one to your daily walks and you'll be shocked at the difference it makes! LTKFindsUnder100 LTKSaleAlert LTKActive
