Check it out... I recently was desperate for work, and had to take a manual labor job due to the good pay and schedule allowing me to go to school... It's only 3 days a week. Fri-Sat-Sun for approx 11hrs a day. It's extremely fast paced... you get a 20 min break 3hrs in a 30 min lunch 5.5 hrs in and then a 15min 8.5 hrs in. Other than that, you don't stop. You never stop moving, you're lifting and running. It's all production and very hard to reach 95% (as you're timed) so you can't afford to stop and talk. Anyway - I've only been at this place for 5 weeks... and EVERYONE there is fucking ripped it seems. We wear extra clothing due to it being 35 degrees in one part...-10 in another and -20 in the other so it's hard to tell. But on breaks, without sounding like a homo - people take a few layers off...and almost everyone there is in great shape. Just in my 15 days there or so, my abs are visably more defined, i've got veins running through my arms i've never seen before and my chest has tightened up a good bit..... and I'm not even pulling production but 1 day of those. Due to being in my training period still, i have the ability to coast and not reach 95% without penalty. I used to heard that the best workout routine was 3 days on, 4 days off?... Is that correct. I can't imagine getting a better workout in a gym... full body. I've never been near as exhausted after working out at a gym either. So will this stop once my body gets more used to it? I havent asked anyone there if they got built from the job alone, but it seems that way. plus, you have to eat nonstop there. I eat 2 PBJ sandwhiches per break and leftovers for lunch with the free fruit they provide on the sides. opinions on this? may be all my imagination but i dont see why it couldn't work.
