Why would you shower before a work out? I'm literally dripping in sweat after a work out. Although she's barely breaking a sweat is she.
Rebecca when you squat keep your chest up, don't lean forward so much. When you're doing the opposite arm and leg it needs to be more controlled, stop swinging, don't let your back drop and arch so much. Think about what muscles you want to train and make sure you can feel it in that area otherwise your just wasting your time.
You're welcome.
