You are spot on! The cardio capacity it takes to propel a man of that size up a hill is huge. For backpack hunting a little cardio and losing a few pounds goes a long way..............
Okay, I've got another little test for you. Load 95# on a barbell, walk out into the yard with it. Do ten lunges, dipping that trailing knee all the way to the ground each lunge, drop the bar and hop from one side of the bar to the other ten times. Then clean the barbell and repeat five times. If you can do that without stopping, you might have passable muscular endurance in your legs.
Easy!!!!
Get on a stationary bike and hold 400 watts for five minutes. You likely last one minute and blow lunch on yourself.........
