Hi there, I was just wondering if anyone could give me any insight or advice to help me. I attended a Pre-ADSC yesterday and my running was just diabolic to be frank. We did the PFT (with heaves). I managed 0 heaves, 42 Press-ups, 46 sit-ups and my 2.4 km run in 12.50 However my usual run time is around 11.20 (PB is 11 flat). I just felt really out of breath after 800 meters or so and it was just all down hill after that, I am surprised I even managed a 12.50 run with how bad I was running. Is there any reason why this is? my obvious thought is the press-ups and sit-ups took more out of me than I thought, also I felt the sit-ups were working my legs, more than my ab's. Am I just being bone and should of pushed harder? Currently I do running 5 days a week and alternating between doing 3 mile runs and testing my time. Also doing circuits to build my core strength up, Press-ups, sit-ups, squats etc. But i really don't think these are helping my heaves and I cannot even achieve 1, so how am I supposed to train for these, when the age old saying is 'get better at something by doing them.'? I do my circuits in the morning and running at night, should I set one day a week aside and do them together? Further information is that I have another Pre-ADSC in 2 weeks and my recruiter wants me to get me below 12 minutes before he sends me off to selection. Any help is really appreciated, if its a complete change to my fitness schedule or just a small tip or hint. Of course I want to improve everything including my press-ups and sit-ups, not just my heaves and running. Thank you in advance.
