How Many Of You Regular Posters Use a Training Site/Coaching?

I am curious to see if there are any posters here who actually use a training site/coaching for live NLHE.

My opinion is that the vast majority of the regular posters in this forum would get a very high return on their investment into a training site subscription/coaching/etc. But I suspect that almost none of the regular posters here use training sites/coaching.

I am not a world class pro in my player pool, but I got back into poker from a serious rec background after COVID. I didn't get training site subscription until a couple months after I got back into poker, but I have found that my live NLHE game has gotten significantly better ever since then I did make that investment.

I guess we could also discuss the return on investment that others have had with training sites/coaching. I am personally really happy with the investment that I made in myself.
