Iv always trained my abbs and biceps same as anything else by adding weight and hitting the 8-12 rep range. So for example one of my bicep excersizes is weighted chins and for abbs one excersize I do is decline crunches holding a weight plate behind my head.
However Iv watched a few vids from people such as brandon curry who suggest mostly for abbs and sometimes biceps to not use weight at all and just do unweighted reps until failure.
What are peoples thoughts on this? I thought without increasing weight I wont get anywhere? I mean unweighted chin ups, am guna be there going up and down all day!
