I recently bought this weighted vest for walks/runs and turns out it's exactly what I needed to add a little extra challenge to your walks/runs. I got the beginner vest 8lbs. Two front pockets to put your phone, keys, ear buds, etc.

Huge gamer changer using these ankle weights to your walks/runs. You can use them on your wrists or ankles to add extra weight to help gain some muscle while walking!

I have been basically living in this active dress! It's a nice slimming fit dress. I do everything in it. Walking, running, gardening, chores, you name it.
