I'm going on vacation with my family for a week. I'll be out of the gym a whole week, and I'm worried this will affect my progress on SS. Not only that, but my diet will be shit as I'm gonna have less control of what I eat. How should I approach my workout when I come back? Do I start again with the same weight I left off or do I deload a bit. I'm hoping it won't be that bad and I don't lose too much strength.
I had about two, 1-2 week breaks during SS because of travel. As Milo said, the extra recovery time made me feel fresh and no less strong when I returned. I felt like those spread out breaks were good for me. About a potential deload or not, if I felt like I was going strong on a lift, I just repeated the weight on that lift then kept going. There were one or two of the lifts where I felt like I was very near to a stall before leaving -- on those lifts I took off 5 or 10 lbs and then kept on moving. So I would say that, for me at least, I took a variable approach.
On the food thing, yes, enjoy the vacay. I just came back from a week long family vacation, and I figured I would be heavier, but was at the same weight. I enjoyed ice cream and all the fun things with my family, and didn't hold back on dinners out, etc. But I did mentally "cut back" on breakfast and lunch a bit, and early day snacking in between. I just made sure I hit my protein at all meals, and cut back on a few carbs for breakfast and lunch...
