I am 6 ft. last week i did dips and it was very hard for me to do 3 sets of 6 was about it i leaned forward as much as i could . it was kinda pain full not in a good way. so this week i mixed it up and did bis and tris on Sunday and chest on Monday.i went to dips first and could hardly do 1 set of six so it leads me to believe i still using tris to much and they were just wasted from the day before the rest of my work out looked like this. flat 3 x 10, incline db 3x8, decline db 3x8, machine flys 3x10, cable cross overs 3x10, and some very pain full db pullovers..(ouch i should have stopped with the first set) shoulder better this morning but i think ill hit legs today instead of back to further rest the shoulder.
