Landscaping - Moving huge rocks, shoveling rock

Not only carrying huge rocks but I was stacking them on the dolly to get them around the house.  We talk often about workouts focused around functional movement.  We did Hack Squats just a few days before this.  That was the exact movement I used to lift the dolly.  We do partner pulls and sled pulls all the time.  I was pulling the dolly up hill and around the house.
