It's been nearly six years since I've worked out. After having five kids I can only work out at home. I am so out of shape I feel as if I've never worked out a day in my life. I am looking for advice as to what are good videos to start with at this point. I really love step, but I'll try anything. The CATHE videos I've seen are sooooooooooooooooooooo advanced! Are there any for a beginner? Please help!
