I’d have to agree with Gojira, two a days are probably not the best course of action for you right now (seeing as this is in the beginner’s forum). You really have to have built up quite the work capacity to be able to handle twice daily workouts, and even then I personally don’t think they’re optimal for putting on mass (some might disagree).
My workout are
MONDAY- Bench, Incline Bench, Standing Cable Crosses, Deads, Pull Ups, and BB Rows.
TUESDAY- Standing Shoulder press BB, Shrugs, Side raises DB, BB Curls,
Seated incline curls, Seated Hammer curls, Cable curls, Seated incline press ez bar , Cable pull downs, Dips,
WEDNESDAY- Squats, Leg extentions, Leg curls, Lunges, and Cavles,
then repeat day 1,2,3 over for the rest of the week and rest on Sunday, I also do some abdominal exercises at the end of eash workout.
Even if you were ready to do twice a days, there is no way that you would be able to do the above workouts. With two a days you must keep the volume (and intensity) fairly low per workout session. The total volume per week will wind up being quite high though. The above workouts would have you quickly overtraining and possibly getting injured. Not good.
One thing to remember is that you don’t grow in the gym, you grow out of the gym. The gym is simply the stimulus to tell your body to grow. From there you must give it ample time and materials (nutrition) to build itself back up, stronger and bigger than it had previously been.
By the way, I still don’t think you’ve told us your goals. Trying to give you direction without knowing what destination you wish to arrive at is pretty tough.
If your primary goal was fat loss. then perhaps twice a days might be a viable option (though not the workouts that you listed above) as they will certainly allow you to burn lots of calories, thus making it easier to be in a caloric deficit.
If your primary goal was strength or muscle mass though, not a good idea.
What are your goals?
