I used to do lots of heavy weight lifting when younger, but go with a much more balanced approach now. I'm more likely to use bodyweight type exercises (push-ups, pull-ups, etc.) for building strength/endurance with a little weight training thrown in. I also do hiking, building up gradually in terms of the amount of weight I carry in a pack and the distance. Used to always go "balls-to-the-wall" with weight training and would sometimes injure myself and require a long recovery time. With age, Ive finally learned my lesson. - - - My motivation for working out is the elk bowhunting season ! Youre in steep, tough mountain country miles from the nearest roads. If successful you get to pack out hundreds of pounds of elk meat on your back over several trips. Balanced strength & endurance help a lot. - - -
