Everyone has that one friend who puts you to shame. The one friend who gets up an hour early to hit the gym, whilst the rest of you are sleeping off the night before. Well, this festive period you could help to make their gym bag a little bit more stylish by buying them something chic to wear whilst working out. There are some great items available now which make exercise more fun. This includes Stella McCartney's Team GB t-shirt (£28) and Sweaty Betty's yoga capri pants (£45). You can shop these pieces by clicking on the images above.
