No Xplode Can Cause Enlarged Heart Is This A N.O. Xplode Side Effect?

Is this a N.O. Xplode side effect? - no xplode can cause enlarged heart

When I am training very hard, if I stay for about 20 seconds, just to breathe. I think I can hold my breath, without catching their breath after a certain amount. (my games are 1 set of 12 1 of 10 1 rate set of 8 and 1 of 6 Inbetween without interruption set)

Earlier, when I suggested a product that my heart feels as if he was on my chest with NO Xplode pounds I can still feel fast without the connection remains. Do I have to work very hard to get used to or is it not caused Xplode?
