ok here's my question with these mag workouts, every workout i see give you a set and rep scheme like so : 4x8-10 for example but what does this mean does this mean 4 sets of pyramiding the weight like : 1st set 135lbs for 8
2nd set 225lbs for 8
3rd set 315lbs for 8
(working set) 4th set 405lbs for 8
or does it mean :keeping the same weight and hitting failure on all sets ?
also which method is better for bulking 4 lighter sets to failure or 1 heavy ass set ?
can someone clear these up for me need to know some answers real quick !
