Haider & Pumpster are correct about GVT. You are doing 100 reps broken down into 10 reps each. The same lighter weight is used throughout the whole 100 final. Rest will be 60 seconds, have a stop watch handy. Do not have to be a math whiz, it's just 10X10= 100 reps. Though a light weight, it can feel three times the weight on the bar for the last couple of sets.
Poliquin has a four day rest beteen worked body parts. (Side Bar:a old friend of mine met him casually once about a year or so after his heart operation. Very short man but with very large arms...look of serious power) His version was probably SS's. The classic version is one exercise ,per body group, only for the 10X10's. Once a week, like monday:bench, wednsday: squat and friday BB rows. Examples only. But no matter, lot's of different versions have been used throughout the years.
I pray that Davie's mate is not doing all those exercises listed in one workout!!! Working the bicep/tricep with GVT is not always the best idea, though some guy's can do that and make gains. GVT is designed for the big compound exercises, like squats, DL, cleans, rows, military presses, etc. Olympic lifters used GVT off season for less stress on the joints while still keeping power. Some of them found much increased power in their lift's and were adding muscular bwt. Some so, that they could advance to the next higher bwt division. Good Luck.
