Navy "probationary": 1.5mi in 15m30s, i.e. 5.8mph. I'm sure I can do that, since I can sustain 6.5mph for 1.0mi.
Navy "medium satisfactory": 1.5mi in 15m15s, i.e. 5.9mph. I could probably even do that on a good day.
Marine minimum: 3.0mi in 30m, i.e. 6.0mph average.
Army minimum: 2.0mi in 18m42s, i.e. 6.42mph.
Part of me wants to predict: it will take a month, or 2 months or 3 months. Fact is I don't know. Liz predicted a 30-minute 5K by June, and I scoffed; but having hacked the mile at 6.5mph, I'm not scoffing anymore.
This website uses a simple height-vs.-weight index to return BMI (body mass index). Let's assume I'm 5'9" (I might be closer to 5'10", I'm not sure anymore); at that height, 204# or more is reported as "obese". Last winter I may have peaked there or higher. I'm in their "overweight" range as low as 170#. As I've said before, weight-loss is a desirable corollary, not the main focus of my fitness goals, so I'm not rushing out to buy a scale, just curious where I fall in the range.
I've never been particularly opposed to sit-ups; they're just boring. Push-ups are a different story, but for the first time in my life I can actually see myself pursuing .mil-grade upper-body fitness.
Navy probationary: 24 push-ups / 2m
Navy medium satisfactory: 29 push-ups / 2m
Army minimum: 30 push-ups / 2m
