I usually find that I bleed alot more than usual while on. While on some fina and EQ I was doing some heavy squats. After I racked the weight a few guys came up to me and told me the back of my head was bleeding and that it was dripping down my back. I went to the bathroom and found indeed there was quite a bit of blood, looked like some pimples had burst during squats. I think this was due to high blood pressure during the squats. Needless to say, I wiped it off and went out to do some finish my squats, bleed on each set.
