Jenny Evans has the uncanny ability to apply very solid scientific information in a way that any busy person can use. That's why I believe in PowerHouse HIT THE DECK. It's based 100% on sound scientific evidence and this variable workout is great for those just starting out as well as the advanced exerciser. Without question, you will get a very efficient and effective total body workout!
