I did 3x10 box jumps with just the box, then ½ plates for the last two sets. Did doubles up to my max of 9, where I got it on the first attempt but my legs were so dead from leg day that my mind wouldn’t let me get anymore. When I started box jumps I couldn’t even get up onto this box, I started on the smallest box. I’ve been doing box jumps on and off for a few months and I’ve already come this far. My old trainer can do 14 plates on the seated ones so that’s my next big milestone for this exercise.
