whats most effective? lifting 1 or 2 body parts per day, per week, on a 5 day run w/ 2 days off.(going all out heavy to failure) for eg. chest(mon), tris & bis(tues), legs(wed), back(thurs), suoulders(friday), abs every day of course w/ cardio 3 times a week (sat & sun off). with this workout on juice i feel stronger & look thicker, but i dont look as cut as i know i should be. is this to long of a gap between the next muscle training. (trying to add mass)

or this workout that i sometimes did when training natural! supersetting: chest/back(mon), shoulders/bis/tris(tues), legs(wed), (off thurs) friday follow the pattern(chest/back), sat(shoulders/bis/tris) sunday off. this workout hits the muscle every 4th day or so, & w/ this i noticed more tightness & cuts, steady strength growth. whats good to do bros. thanks
