I really covet the work-out clothes from sweaty betty.They are stylish and practical, unfortunately that level of quality comes at a price and I will need to either save up or wait for a sale (or both) to buy some cute gear. In the meantime there are lots of great lower-budget brands too such as karrimor, H&M and nike (my favourites)

Another great thing about sweaty betty is that they offer free in-store fitness clubs. Check out videos here:
