Just the tip?
I hear violent masturbation is a form of HIIT. Confirm/Deny?
Isn't Cap like 24?
That's a pretty damn good description. Frank, it's when your muscles that are engorged with blood can't drain that blood, so they stay full and hard for much longer than you want them to. It's a constant nagging feeling to crack your back, but it's impossible to do so, so you writhe in agony all night long. Ab pumps are the worst, followed by back and then calf/shin pumps. Nothing like doing tricep pushdowns and your abs staying rock hard for hours - then it becomes a full on cramp, where you feel like your abdomen just caught on fire and THERE'S NOTHING YOU CAN DO ABOUT IT. LOL. (Taurine is indeed your best friend.)
Ana Anavar (var) /Dbol/Tren/Adrol have all given me pumps, but Anavar (var) being the worst for some reason.
