right now my work out routine looks like this mon.- chest/tris, tues- back/bi's, wedn- shoulders/abs, thurs-legs, and fri- chest/tris again each muscle gets 4 different excercises at 4 sets of 10. and 2 days out of the week i throw 20 minutes of cardio in only 20 minutes because im trying to gain weight im only at 160lbs but would still like to increase stamina. i was just curious if it would be better to work change my workout routine to where it looks something like this mon-chest, tues-arms(bicep,tricep,forearm) wedn-back, thurs- shoulders, fri-legs/abs and off on weekends. or does it even matter?
