Thanks everyone for your input on the Cross Train Express Series. I just got the videos and have tried 2 of them, and my arms are killing me!!! I love the videos, glad I invested in them. I use to be an addicted Firm believer, but since discovering Cathe, I'm done with the Firm. Cathe is incredible, I actually feel I've done a worthwhile workout after one of her tapes. Thanks all....looking forward to buying more.
