Hi, I'm doing the same thing,i'm getting the vest,shorts,belt,ankle and wrist weights of the most comfortable and highest weight over a period of a couple years and see how much my body can take before it gets to heavy. But say if your comfortable with like 40pounds after awhile don't jump or fall from heights with it. Only jump half the weight your comfortable so no damage is done to your body. Not sure about what weight u should be jumping with at how much weight u can hold really, but sounds somewhat logical.
