I run the gamut on what I need, even in Meso 2, I still use weights at low as 8 and go up to 35's. I add weighted gloves and wrist weight to add incremental weights when needed, and have a 10 pound and 40 pound weighted vest for leg work. I'd say the one that get the most use are the 12, 15, and 20's for upper body. Lower body is another story, the most used for leg workouts has been 25's and 30's, but I go much lower on anything that has paper plate slides. I also use a barbell, so far my highest chest press weight was 71 pounds.
