Well, yes, it does. But only very shortly. Maybe you could go to the HST website or just search "strategic decondtioning" and see what happens in this time off. It's really good, I'm sure you've read about how you have to keep on adding higher weight to get the benefit of weight lifting. Supposedly, if you take this time off, you "decondition" the muscle and therefore you can use lighter weight and still build muscle.

Anyway, just search HST and read up and maybe apply part of what they do to your situation (like the lower weight / higher rep) after this "deconditioning". LIke I said, works for me! So don't be scared to take time off when you need to again, just learn how to use it to your advantage
