70-80 lbs sandbag work. Alternated various exercises and stair climbs. Between each set of exercises I kept it on my shoulders, or bear hugged it and carried it around with me while I sucked in some much need O2. Never set it down for 35 minutes. Felt like I could float when I did. Caught my breath and knocked out a few sets of dead hang pull-ups. Resting today and making food for my weekend at work meals.
