I always assume everyone else is superhero strong...Ummmm...no! If I could hit those numbers with sand I'd be a superhero. 400lbs of sand would be about the size of metal trash can. I do need to pick up some chain, but that's not cheap.
I don't know exactly what it is about sandbags, but everything feels heavier with them.
I see. It looks really heavy and has a nice thud-sound when you drop them on the floor. Like in MMA-training when they do squats with two people on their back.
Bags like these are up to 135kg, the one's you're using doesn't look that much smaller, a bit longer and narrower. Are you sure you're not just being humble?
