I don't want to jinx it, but I think I've hit that point where you have enough lean muscle that you don't lose it if you don't work out every day or every other day. Because of work, illness, and general laziness I've only worked out upper and lower body once a week each for the past 3-4 weeks, but I still have most of the mass I gained from the past few months.

I really want to get back into the gym, but now I'm going on a trip and still fighting this bug that's got me hurting. Hopefully next week I'll be able to start building again.
