Adding weight needs to worked up to. This allows the cords creamaster muscles to get strong enough to carry more weight. You don't go to the gym and grab the heaviest weights to work out just because the handle fits your hands. Muscles have to be only pushed to their limit and no more. Pushing before the muscle is strong enough leads to tearing and scar tissue that will no longer grow. It takes time working with a weight to build the muscle up to the next 8 ounce or 15mm weight step.

I believe that at this point I have a decent amount of experience with ball weights and a good sense of self awareness to be able to vary how much I weight up my balls,but this is because of the unique requirement of my job,and the long I hours I spend on the job.I DO stay within Jarod's recommendations,however my circumstances do not make it possible to keep such a neat and steady progression in weight and daily routine as would be possible if I were performing something else for a living.I have to vary my weight based on what I anticipate my physical antics to be during the coming day,and the amount of hours I plan to work during the work day.
If I had a more predictable and more sedentary work life at the moment I would be wearing about .75 kg as a 24/7 weight and would transition up to about 1kg of weight over a 3 month period,and keep things there. Presently,I wear anything from .33 kg to .75 kg during my work day and usually .75 kg after work hours and overnight. I need to lighten up on the weight mainly for two reasons,the first is,I may not be able to lube my weights and sack for a period of 16 hours and the heavier the weight,the more friction against my work clothes this creates,a lighter weight will not rub my skin raw.I am on my feet for up to 12 hours at a time and probably clock several miles of walking in a typical day,LOTS of friction.Secondly,if I am operating machinery or doing work that requires me to perch on,or straddle certain objects,taller weights get in the way and have me accidentally sit on my balls at times,this is not fun.
The thing I have to be most mindful of is high impact type of movement,such as jumping and landing.With .33 kg it is not really a concern,but .75 it IS a concern.I have almost eliminated these maneuvers since I have been wearing ball weights and my joints also thank me for it. I believe that ball weights and high impact activity do not go together at all,and I do not risk it.Weight is weight,but what you are doing while wearing it,the position you are in and the clothes you wear are just as important with the forces created on your sack and testicles.
