Lady Gaga gets a killer workout whenever she's on stage, but she also has the benefit of having Harley as her trainer — he even goes on tour with her! To keep Gaga in shape, Harley keeps her on his 5 Factor diet and makes sure that she works out five times a week for 25 minutes a day. The secret to Lady Gaga's killer abs? Lots of crunches. Harley starts her on a basic crunch and modifies that into reverse crunches, ending with a double crunch. Gaga's also a pretty good cook, even helping Harley come up with some recipes for his 5 Factor World Diet cookbook.
