Agree on both, however a good, no fool around weight workout also will be a decent cardio. Didn't mean to skip the biking altogether.
However, I once asked an Alaskan guide who was an ex Army ranger how many hunters he has encountered that could keep up with him. He replied only a couple and one was a marathon runner.
Update on the 3x5:
It works. No big deal to the younger, bigger, stronger crowd, but a deadlift of 200 used to be a grunter. Now 210 is not that big of a deal. Only draw back is if you want to keep getting stronger you have to put on some weight. Something I don't want to do in that the knees/hips don't need or want it at this stage of the game. All in all a great program to add strength.
