whats up dudes so heres the deal... i work for ups unloading cargo trucks and to anyone who doesnt know, this kind of work is no joke. 3 hours of streight cardio/aerobic workout fast paced lifting and lowering of packages. then a 15 minute break. then another 3-4 hours of this work. the first 20 minutes of unloading and im already dripping sweat. supervisors yelling orders as if were doing military drills.
question 1- 95% of the people doing my job are skinny, malnourished, sickly looking men, and i myself have been dropping body fat(yet maintaining weight) does this 6 hour cardio session allow for a more than 4000 calorie a day diet without gaining fat?
question 2- is 6 hours of cardio enouph to cause muscle atrophy?
question3- after doing this job 6 months, ive noticed ive obtained over developed front delts and upper back due to numerous end ranged motions. making me look like i have bad posture (hunchback). does anyone know how i can incorporate this into my routine to even out the imbalance?
