Beginer here with a question..

this is my routine..
 
set1 10-12 medium weight
set2 8-10 medium weight
set3 6-8 heavy weight
set4 4 with heavy weight
 
my exercises..
 
bent over row
bent over latteral raise
seated shoulder press
standing latteral raise
standing bicep curls
lying tricep extension
chest press
chest flyers
lunge
crunches
 
All done with dumb bells..
 
Thats my routine and im taking that basic Met-rx shake 2 times a day for my first week than ill go up to 3 shakes a day my second week..
 
But my question is, how many times a week should i work out on this kind of program?

None.
For the best results, each muscle should be worked- That includes calves, hamstrings, lower back- Everything. It's also not a good idea to try and work everything in one day- It sounds like that's what you're doing. Try working everything once a week, and adding more exercises to each muscle group- Perhaps like this.
Monday- Chest
Flat bench, incline bench, decline bench
Tuesday- Legs
Squats, stiff leg deadlifts, calf raises
Wednesday- Shoulders
Military presses, arnold presses, shrugs
Thursday- Back
Deadlifts, bent over rows, pullups
Friday- Arms
Barbell curls, reverse curls, alternating dumbbell curls
Close grip bench press, skullcrushers, triceps pressdowns
 
Or, if you want to work everything twice a week, try this-
Monday- Chest and back
Tuesday- Legs and shoulders
Wednesday- Arms and abs
Thursday- Same as Monday
Friday- Same as Tuesday
 
Arms and abs only get worked once a week with this- But they get a lot of work as secondary muscles during some of the other workouts.

Alright thanks for the info CPL.
 
I have one more question. Would it be wise to lift late at night at around 9:30pm than have my 2nd or 3rd metrx shake of the day immediately after that late workout only to end up falling asleep not to long after that? would that be ok for the body? I ask this because I heard the mornings are the best time to lift (I dont know why) and I been wakin up at 6am and 6:30am to lift but I wont be able to do that for long and the only free time I have after that is around 9pm..

Lift whenever you can. Try having the shake right before your workout. But enough about shakes- What do you actually eat during the day? Your actual food diet does about eighty per cent of the work or more- Relying on shakes isn't the way to get gains, and they really are most effective when coupled with an actual healthy diet anyway- So list what you would normally eat in a day, and we'll help out from there.

metrx shake in the morning

hardboiled egg, apple, and a bottle of water at around 10am

plain turky sandwich with just mustard and a diet pepsi or coke for lunch

(next week ill be havin my second metrx at around 4pm)

for dinner ill have half'a skinless chicken breast thats cut down the middle length wise (today i put tomato sauce over it -10 more cal's with 0% fat-) salad with fat free dressing, and a plain baked potato at 8pm

than my 2nd or 3rd metrx shake at 11pm..
 
im pretty sure thats less than 1600 cal's a day since im only drinkin 2 of those metrx's, but im tryin to lose a lil weight cause im 5'8 160 with no definition lol..so either next week or the week after ill throw in my 3rd metrx..

You definitely want to find out how many calories a day you should be eating- Check out the calorie calculators at the top of the nutrition forum, you'll learn how to find an exact number based on your info. At your height and weight, believe it or not, you may have to eat a little more to effectively lose fat.
