Turning 60 in the next year, fitness has been apart of most of my life. Wanting to live on the edge at 12000 ft. and beyond. Planning that next hunt, 6 total maybe 7 hunts this year. Any fitness tips for that guy or gal turning 60 and beyond. Currently working upper body, free weights every other day. Core every other day, and cardo 4 times a week with hikes in between. Im 5ft 11in and 173lb. Lean. Thanks, Im headed to work 12hr. shifts Evan.
