Great sequel...so much better than that awful looking movie,"The Change-Up" could ever amount to. Do they have Terry Bradshaw, Kirk Cameron, or Matt Lauer? Nope they do not. They don't even have an alien machine or weird switch-a-roo mess-ups. However, this book has all that and then some. So, if you liked the original Muscle Memory and have been jonesing for a sequel, look no further than Steve Lowe's blog -----> http://steve-lowe.com/ It'll be worth it since it's much more entertaining and best of all free!
