Hi all. I just got a rude awakening today. I do about 170x6 for cable pulldowns. However, I weigh 200 pounds and absolutely suck when it comes to pullups! I can only do three or four, and that is not even bar all the way to the chest. I am seriously considering joining the marines and to get a perfect entrance score I will need to do 20 pullups (as well as 200 situps in 2 minutes, I believe). You only need to do 3 to get in boot, but I know a very high entrance score looks good and ups my chances for promotion. Besides, being in tip top shape can only help me.
So my basic question is what is the fastest way to get where I need to be? This goes for the situps and the pullups. Should I just bust my ass multiple times a day doing as many pullups/situps as I can, or stick to once a week? What about other back exercises, stick to the 4-6 reps I'm doing now or should I change my whole body to 20 reps or so? I know I will lose weight but that actually helps me.
BTW- IIRC, perfect entrace score for running is three miles in 18 minutes. I'm not holding my breath on this one since I basically have no endurance now, but I will work on it. What is the fastest way to increase my running speed?
