You’ve posted the 1,000 lbs thing before.
What, exactly, do you think doing that accomplishes?
You’re not building endurance, you’re not doing cardio. It’s not going to make you a better hiker or runner.
So what is your goal in doing these?
My core/lower body workout includes leg presses. I’m working on strength, endurance, and doing reps. Reps are important if you’re planning on using the muscles for anything other than lifting weights.
I do sets of 10, for 5 cycles through the gym. Any time I do leg work, I also work on flexibility with high knees, high kicks, low tiger stretching, and other exercises.
I do this with hiking, rough terrain, and carrying a heavy pack in mind.
So, again, what are you trying to accomplish?
