I'm a huge believer in muscle memory too. You tend to become a believer when you have lay offs (enforced or not) and then start training properly with good diet, it all comes back fairly quickly. Though less quick as I get older.

Not suggesting for a minute that you believe you have lost 5% bodyfat in a week but I know some people will read the stats stated and believe it. Would be nice if it were real though!

So, after the 3 week blast do you have a follow up plan or is that dependant on the progress made in the next 2 weeks?
