In an effort to lose weight, but save my knees, I worked out on the Elliptical or went cycling for months. I just started running in the fall, and then I got the call in December, so now I'm in panic mode!!
I run intervals, usually on the treadmill, because it's too sloppy outside lately. I do mock shuttle runs on the treadmill, but at much higher speeds than required for the test, to make up for pivoting. My treadmill is in miles, not km, so I'll start at 6, and then increase by .5 every minute. Actual shuttle run speeds are 5.3, 5.6, 5.9 and so on. I usually die around 8mph.
Sprinting is not a problem for me, but distance running is, so I'm doing my best to increase my endurance. To be perfectly honest, I'm scared about endurance.
I do my sit ups on an incline (Total gym). I hang upside down, and can do sets of 25 comfortably. I do lots of pushups. 8 months ago, I couldn't do one. Now I can do about 20 before failing.
In addition, I do quite a bit of resistance training. On days when I don't run, I'll do some sort of cardio. Today I walked 8k on the treadmill, in 1:15. I was trying for 13k, but my calves got very tight, and I didn't want to hurt myself. I'm not even worried about the BFT though. I can walk forever. I may change my tune with the added weight, but they'll work us up to it anyway, so I won't stress about it.
If anyone has suggestions to increase endurance, I'm all ears!
