Actress Emma Watson is a firm believer in the motto, "There's nothing to it, but to do it!" Working out, that is. Watson is a dedicated athlete, and her regimen involves five days per week of intense cardio -- such as Pilates and sprint running -- coupled with weight lifting three times per week, according to Glamour. Her intense regimen may not be an easy one to follow, but you can modify her routine to fit your lifestyle. Carve out some time for fitness every day during the week -- whatever you choose to do, just try to keep consistent.
