What kind of program are you using?
Just interested in seeing what kind of program each of you are on and why?

i believe in listening to your body. i use a 3 day split with a break after 6 days. chest/shoulders/triceps, back/bi's/forearms/traps, and quads/hamstrings/calves. i do cardio 3-5 days a week after my weight training for a half hour and 2-3 days first thing in the morning for an hour.

i use a 4 day split. wen, sat, and sunday off from weight lifting and on wen and sat i do 30 min of cardio. if you want to know more message me

5 day slit is the best. lots of rest but all muscle groups get hit hard. You have to hit the muscle from every angle. (just like Arnold said).

No split is the "best", unless it is the one that is working for you at that moment. (Arnold would also spend 6 hours a day in the gym, and lift while he was in bed!! Which is why he was constantly over trained, never got above 240 at over 6 feet tall, and had very tiny legs.) Your split should depend on how fast you recover,(some bodyparts might take longer than others), how much time you have, and what your weak points are. Example: If your legs are weak, and you don't train on sat and sun, hit them when you are fresh off of two days rest and full of energy, even though Monday is National Bench Day!
To show you a split from outside the box:
Weak points are back and chest.
Day 1: Chest
Day 2: Arms
Day 3: Off
Day 4: Back
Day 5: Legs
Day 6: Off
Day 7: Chest
Day 8: Shoulders
Day 9: Off
Day 10: Back
Day 11: Arms
And keep continuing, so your weak points get hit more often, and always after a rest day.
