I always wanted to run a marathon; 26 miles.
However, some advanced runners I talked to a couple years ago told me it takes years to train for and months to recover from, even when the runner has all the genetic traits that benefit endurance running; long legs, short torso, slight frame, long arms, almost no sub-q fat on the limbs, chest, or stomach but having visable sub-q fat on the hips, lower back, and buttocks.
I use to love running, but it gets old after a while. Plus, working opposable muscle groups to failure in a circuit, 4 sets with a 45 second rest between groups, ripped me up better and faster than running five miles four days/week on an empty stomach did.
If you push yourself every set and stay focused on making it hurt, six days a week for a total of around three hours of gym time/week can, especially on an ox/winny cycle, really get results. On cycle, I prefer to work each muscle group twice a week.
Monday - Tris and bis (the pump from this is awesome), then decline abs with weight, 4 sets to failure around 8-10. Switch up your excersizes often, 4 excersizes for bis and tris, failure at 8-10 reps for bis and 12-15 for tris, 45 sec rest after doing eight sets (between change in machine, weight, excersizes, whatever).
Tues - Chest and back (talk about pain). Four sets for each, four excersizes, two heavy and two target, failure at 4-8 reps, 5 second negative motion and five second positive.
*Sounds like confusion, but you learn to pair excersizes up that don't require more than a few seconds between sets, like dumbell presses paired with dumbell rows, etc.
Every odd Wed - Legs and shoulders (shrugs on this day)
Every even Wed - Deads and shoulders (lateral flys here)
Thur - rest
Of course, few people ever get past Monday when trying this
