I am trying to decide on a good max weight to get. Currently I am looking at 70lbs but really in the back of my mind thinking the 120. I am thinking the 120 might be more than I will ever need, but at the same time I dont want to invest big bucks in a 70lb one and realize I need more. It would be for:
-Planks and still movents
-Body-weight exercises of all kinds of varieties.
