Just purchased the brute force spartan sandbag kit, it can be filled to 120 lbs and then as I need, I will buy the next shell and filler bags. Really looking forward to this arriving and can't wait for it to arrive, I'm on a great program given to me by a buddy of mine that he used in the military. As far as other implements I have a tire that weighs roughly 180 pounds, a marine rope for pulls and various exercises. Really a big fan of functional training and thoroughly enjoy the benefits of implement training.
My question to you, every sand bag I've used for sandbag slams has ripped to shreds in a single workout, anyone know a bag that can take that in stride?
