In a magazine I recently read, there was an interview with a danish actress that I unfortunately can´t remember the name of. Nevertheless, she was absolutely gorgeous as acresseses tend to be =)
Anyway - she revealed that every morning she did 10 Sun Salutations. I started to do this in March, and I´m addicted to it. If you are in need of extra energy then I definitely reccommend it. You can google the exercise if you haven´t done it before.
