Ok guys thought I'd chime in. Just back from a 3.25 mile run with some pretty steep hills. 70 pushups and some curls with a 25 lb. dumbbell . Run every other day rarely miss. Do 50-70 pushups every other day as well. Have been keeping track for 2014 on the pushups this makes 1640 so far. Since I am 5' 11" and weigh 140 running is what I do best. Will start doing 400 meter intervals on the high school track when the weather breaks. Maybe do a couple 5k road races this spring to see how I hold up in my age group.
