I used to do some levering excercises and some sledge against a tire for a workout.
This is great!
I 've done 4 solid workouts between last week and the weekend.
Sledge is 8 lbs. My back took a couple of workouts to get used to and over the 'day after' mild soreness. I now have a 5 lb. plate duct taped to the end of the sledge for a 13 lb'r...feels good!
Actually just got back from traveling for work (car trip) and had the sledge in the trunk. When it got dark, I went out to get it and brought it back to the room and had a pretty good workout last night. It was great after a 5 hr. car ride. Put it back without anyone seeing me or throwing quizikel looks my way

Plan on another this evening.
Anyway....just wanted to say 'Hello'.
Thanks for the site and the ideas.
