When it comes to gym kit, a baggy t-shirt and a pair of three-year-old tracksuit bottoms will do fine, won't they? Yes - sloppy sportswear will just about do the job, but it probably won't make you feel that good about yourself.
So - whether you're a gym bunny or just want to get motivated (with an excuse to go shopping) - a sportswear update can do wonders for self-esteem. It doesn't have to break the bank either.
H&M has a great activewear range (vests and leggings are £20 and under) and if you do want to go designer, The Outnet has a great selection of discounted items from the Adidas by Stella McCartney collection as well as Zoe Karssen's super cosy tracksuits.
Who cares if it's not quite on trend? As long as it's comfortable, a new purchase will always be an upgrade from your boyfriend's old grey t-shirt.
