Yes, I have 40 acres just SW of Portland and 11 equines. I throw hay pretty much every day. The bales are between 75-95 pounds and I do throw them around. My current batch are in the 90 pound range. Big and dense. I only once or so a year throw tons of hay around though. Mostly I just throw one bale a day. I chop it all up and carry it around to the different stalls. I also do stall duty and push several hundred pounds of horse leavings around in a cart or wheelbarrow (I have 3 of these). So it perhaps is no wonder that I am not getting sore from my workouts in the gym. The 15 pound dumbells don't seem that much.
When I was in the Marines I could lift 125 pound generators and carry them around. I weighed 113 pounds at the time. I have always been a really strong person and more than once beat the guys on the obstacle course. That is why this injury and the weakness that I have allowed to creep into my body is so kicking my ass mentally. I know that somewhere I have strength. I will find it again.
I do have a sledge hammer but don't use it much. I chop wood every week though with a big ol' axe if that counts for anything. I have a woodstove and a fireplace so lots of fuel needs to be burned.
BTW: I am in Santa Clara right now on business trip. I just passed an IN AND OUT BURGER. OMG!!!!
