I am looking at joining the army as an officer having recently finished university, however the years of boozing/smoking have took their toll. I am not overweight, just weak and very out of shape. My current stats are: 1.5 mile run: 17mins Max press ups (2mins): 11 Max sit ups (2mins): 27 I am working temporary jobs for cash but would like to join asap. On a plan of running 3x a week and doing weights 3x a week can anyone give a rough estimate of how long it would take me to get to a suitable fitness? (10mins 1.5mile run, 40ish press ups/sit ups).
