I finished up my third week of the 30-30-30 protocol as of 9-7-18. I'm going until 9-14-18 which will be a 30 day experiment . This is just my opinion and experience so if science doesn't agree there's nothing I can do. I just know what I see and experience. I was going to wait for the full 30 days to give my insights but it has been my experience that my body adjusts and adapts within 2-3 weeks. Especially when I'm doing the same thing everytime I train. Also because of measurements and weight I've seen enough changes to be able to comment. 

   None of this is to discredit anyone's results they may have had. I think age, genetics, and years of training has alot to do with putting on size. I'm at a point where I don't believe my body is going to change much if at all. When it comes to isometrics I seem to get the same results. Differant protocols may put more emphasis either on strength, weight loss, or loss of waist size.

   I originally did this experiment to see if this protocol could put on size as claimed by others. I lost size on my arms(1/2"), my waist(1/4"), and my calves(1/2"). Funny thing is I gained a half inch around my neck. I would probably say the reason for this is because I have never done long holds for my neck so that's how my body adapted to it. I intentionally tried to gain weight which is hard when You work in the hot sun all day 6 days a week. LOL, I gained 4 lbs so not much of a difference. Plus isometrics for me tend to make it hard to keep weight on. So I would say for myself this protocol did not put on any size.

   Now my insights on the one position isometrics. Alot of times I'll use tree work as my monitor on how I feel about an exercise protocol. This protocol did help me feel strong and I feel I didn't lose any strength. But what I noticed is when doing tree work I got pretty sore from the work. I actually have been doing easier jobs than usual. I was not getting sore before I started this experiment when I was doing calisthenics, cables, self resistance and light DBs. Also when I did 3 point isometrics or self resistance I never got sore from tree work. Of course if You're doing this protocol it would take forever and burn You out if You tried it with 3 point isometrics. Anyway, not being sore from work is an important thing to me. 

   I think the 30-30-30 protocol is a great way to exercise. But I don't want to say everyone won't gain size because I believe this depends on certain factors. For me if I was to stay with this I would try differant positions throughout the week.
