I've just bought the 3kg weighted vest from Davina Mcall's Argos range. I'm excited to get going with it! I figured as it was on the lighter side I would wear it all day whilst cleaning the house/going for walks etc and see if I notice a difference or if I need a heavier one. I'm 5ft exactly and weigh 52kg so it's about 5% of my body weight which they recommended. Has anyone else used it, would love to hear your experiences!!
