Yesterday Katie Holmes was spotted at the dance studio in Hollywood, and we couldn't help but notice how thin her arms were looking!

The actress has been hitting the gym non-stop lately, and it seems like she's getting herself red carpet ready, as she has two films coming out in the next six months. The Son Of No One (starring Channing Tatum and Al Pacino) hits theaters later this year, while the comedy Jack And Jill will open in November.
