Are you reasonable healthy and in decent shape? You can apply to work as a loader/unloader/helper at UPS/FedEx.
The holiday seasons is coming up soon and they need a lot of help. I did work at UPS for a while and it was ok. A lot of hard manual labor work.
I did this last year @ FedEx from November until mid-January. Hardest job I ever did, and at 49 I wasn't even sure my body would hold up to the pounding it took. By the time I left, I had dropped 15 lbs (I went in at a somewhat slim 185lbs on a 6-3 frame) and felt that I had never been in better shape, even going back to my years in senior high. I got into what I called 'porn shape', and had definition on my upper body and that 15 lb weight loss came entirely off of my gut. I had a HUGE appetite as well, so I ate more than I have since. I wonder how many calories I was taking in compared to how much I was burning off at the job.
First week your quads/legs will ache, second week your forearms, and the 3rd week it was my elbows and fingers that hurt. My knuckles swelled up so much that I couldn't remove my wedding ring. But at the end of the day, I walked out of that place knowing I had done the best I could - it was a huge sense of satisfaction that I was not getting at my day job at the time. I had a very young group of co-workers on that load area - most were between 18 and 24, and the 'old guy' on the shift until I showed up was 38. On my last day, I bought them all gift cards for local convenience stores and wrote them a thank you card for helping me out while I was there.
It was a blast, and I was looking forward to going back again this year until my left elbow decided to gift me with a bad case of tennis elbow. Little did I know that the recuperation time on this injury is 6-12 months ! I probably made a bit over 2k over those two months on the twilight shift, a 5p-10p shift designed for people like me who needed some extra income after their day job.
