Ive just watched that and to be honest, joining the Army is a little more than doing press ups and lunges.
Im not sure what part of the Army you are interested in or even if you want to be a soldier but if anything, effort will get you a long way, i dont mean the kind of effort that the average joe thinks.
Somebody once told me that' a horse will run till it uses 95% of its energy and lay down and die, humans will run till they use 65% of their enrgy and lay down and think they will die.
Use cardio (running fast for 6 miles) and if needed, weight training and get the right attitude. I never come 1st at any P Company event (para training) but i won champion recruit cos i put 100% into all i did.
The Army will do the rest.
See you at the FRV
