Most days my intensity is heavy sweating and labored breathing, sometimes seeing those little golden bars everywhere after really straining. I have however choked/gagged before, blown snot out of my nose,(kinda grose and not done in front of very many peeps thank god!). For the most part I go home and feel like all is right with the world, I feel a little weak but pumped up and looking very solild and vascular. I LOVE IT!!
