My report:
Today I went to gym. I wore my regular underwire bra, the Go Fit medium sports bra and another sports bra (low impact) over that.
I had almost no tits. Kinda good, actually.
I was on the treadmill and had no problems walking quickly. I tried jogging for a few seconds, my boobs were actually ok. Mind you, this is THREE things squishing them. (tbh my stomach made more jiggle than my tits did here

i has a sad )
