I got it on craigslist (where I get all of my exercise equipment! lol) & unfortunately there is no brand indicated. I like that it has multiple grips. I don't think every one does.
Oh yes, BodyRock! Would you say they are intermediate - advanced friendly in terms of endurance?
I have just begun to use it semi-regularly again recently. I moved recently and am still in a transition with another move coming up very soon out of province. I often cannot find things! lol. The one I bought came with three pre-filled already sewn packages/filler bags within the sandbag. Two are 23 lbs each and one is 50 lbs. Unless I use it quite roughly (I did recently and bruised my wrist.. whoops!), I am hoping not to have to replace these for some time.I'm not sure how BodyRock is. I came across an ad for them and the sandbag caught my eye. Seems pricey at $100. That's not even filled I'm not even sure where to get it filled. How often do you use yours and how is filling it? Messy?
