Well most guys in my gym who have full time jobs usually have a scheduale something like this lets say for EG you have to b to work at 8 and have to leave by 7:30..You get off at 4 and we will base it on the average 8 hr work day...
Get up at 5 stretch and do roadwork finish by 6 and follow up with 1 other thing that doesnt take up to much time sit ups and crunches are a good one because you can bang out 200 of each in 15-20min.
This should leave you time enough for shower change and make it on time..
After work hit gym--
Do average 15 rd work out 3 on each bag shadow boxing rope ect its a 60 min workout if you do it non stop..
Each day work on one additional thing mits,spar 2 days , ect
its about 2-2/12hrs a day you can skip a day or 2 as long as you work out hard during the 2 hrs ur supposed to....on saturday give a hard work out add a few extras take sunday off to recover...
your body will adjust in no time
