I am wondering because I went on a vacation and stayed a little longer than expected. There was no way for me to work out there b/c it was basically a big booze fest w/a 3 day concert mixed in. I missed about 5 days of work. I started back a few days ago but I have a few blank spots in my calender where I missed. I kinda need to stay on the same calendar I made b/c it ends right before another vacation and this one could last anywhere between a week and a month. Should I just work right through my recovery week to make up? I don't really like the idea of resting anyway.

it very necessary. that's is part of the muscle confusion process.
it allow your muscles to recover from all that tearing they incurred during the previous 3 weeks
