I'm trying to gain mass but so far I've only managed to tone up.
Weight; 154lb
Height; 6'1

Need to get to 170lb by next January (muscle), could that be done in 12 months?

Is it a good idea to do a few muscle groups in one day, or split them up over the week? Feel free to critique or add to. I'm working on a trial and error system with this workout

1. Take away the press-ups.

2. Reduce volume but increase intensity of crunches.

3. Replace seated rows with deadlifts.

4. For the legs, just squat for the moment.

5. When I was starting weightlifting, full-body workout works for me, since I was unable to recruit stabalisers. As you gain experience, it may be better for you to do splits.

Personally I would ditch the leg workout you have planned and learn to squat and deadlift. you'll hit your quads and hams.

Personally I like to segment my workout instead of doing a full body workout. I work out monday, tuesday, thursday, friday and train in a karate dojo (but do kata every day =) on monday, wednesday. On saturday I do yoga. generally my workout goes like this:

Day 1: Chest/Triceps

bench press
incline bench press, barbell or dumbbell
decline bench press or chest fly
triceps dip
skull crushers
rope pulldown

Day 2: Back/Shoulders
deadlifts
lat pulldowns
seated rows
lat pull over machine (dont know what this is really called)
shrugs
military press/dumbbell shoulder press
dumbbell lateral raise/upright shoulder rows

Day 3: Biceps/Lower Body
Pull ups
Barbell/Dumbbell curls
Preacher curls
hammer curls
squats
weighted lunges
box step ups

Day 4: Repeat Day 1 with an added ab and core workout

On different weeks I alternate between doing chest/triceps, and back/shoulders on day 1 and 4.

I never do legs twice in a week since it takes me so long to recover.

Since nobody else has mentioned it, I'll say it just in case: EAT. You won't gain weight unless you eat a ton of food, and you won't gain lean mass unless you eat clean food.

Edit: You'll probably need more volume in your program, but not as much as Borrek has listed there. That's going a little overboard in my opinion.

Ok, thanks for all the input.

About the splits (muscle groups per day), I'll stick with the full body workout until I build a good base, but I'll try it at a later date.

Why should I ditch the pressups thought ?

I should have mentioned that I do the chin-ups with a kind of a weighted vest thing, hence the reason for only 5 or 6 per set.

And with the whole food thing, I'm still trying to work out the whole 40, 40, 20 system, and work it into my diet. If anyone as any good siyes with info on this.
