and while i'm all worked up, why are so many people on this board training each muscle twice per week? the only way i would advocate that is if you're juiced up and eating a ton, but even then it's probably overkill...if you're training balls out like you should be, one time per week is more than enough...
thanks for listening
I've done twice per week training before with pretty good results. It's all about finding the right volume. Yeah, if you're doing high volume/high intensity workouts, you'd be foolish to train each muscle group twice per week. But if you're working with a lower volume that suits you, you can get away with it (depending on the person's capabilities). If once per week works for you, stick with it. If something is working for you, use it.
If you're lifting to improve your phsyique rather than just concentrating on seeing your numbers go up, I recommend trying split like this if you're wanting to try twice per week training.
Day 1 - Chest/Shoulders w/ some Triceps (as in 1-2 sets of dips, tops)
Day 2 - Back/Legs w/ some Biceps
Day 3 - Off
Day 4 - Shoulders/Chest w/ some Triceps
Day 5 - Legs/Back w/ some Biceps
I'll go ahead and do some direct arm work at the end of my workout but I usually keep it to 1-2 sets max just because they've already gotten a good workout by working the larger muscle groups. When it comes to arm training, less is more a lot of the time. Go by feel. If you feel like you shouldn't do any direct arm work, don't, and you may see more improvement than if you'd been doing arm work.
I do something like 4-6 total sets per major muscle group. On day 1 for instance I may do 6 sets for chest and 4 for shoulders, then on day 4 I'll do 6 sets for shoulders and 4 for chest. Or maybe a little less depending on how things are going. When in doubt, less (total volume) is more, but go heavy!
Stick with the compound movements but it's okay to add in some isolation work. With the above example, on day 1 I may do only compound movements for chest, then with shoulder do a pressing movement followed by side laterals (isolation exercise). On day 4 I may do mostly compound lifts for shoulders and then do a compound lift for chest followed by flyes. So I mainly do compounds but definitely don't remove isolation lifts completely.
Anyway, if you do try twice per week training, tinker with volumes till you find what's working. Start low and gradually increase if you have to. Just keep in mind that too much is far worse than too little.
