I have been working out for about 4 months now, and I am noticing a plateau in my chest gains.
My gym is limited in its resources, and it looks like a real gym membership is what is needed. (I have no free weights, just 15 different machines to use)
Today's routine:
Flat bench (3 sets: 10 @ 185, 8 @ 205, 8 @ 240)
Incline (4 sets: 12 @ 150, 10 @ 165, 8 @ 185, 8 @ 205)
Cable pull, standing butterfly's (4 sets: 10 @ 30 x 2, 10 @ 45 x 2)
'diamond' push ups (3 sets of 15)

Looks like a lot of volume IMO. I would try cutting your overall reps in half, and up your intensity.

I would say that everything is wrong with the routien.
Working 1 muscle group a day (plus triceps) is a real bodybuilder workout.
You should only be doing this if you are serious about body building and you have been training for a good year.

A good start to body building as im sure Hoss will agree... you should start with a push pull split, gain some strength and not work too much about size.
vary your reps in your work outs... 3x10, 5x5, 10x3.
having a full weeks rest every 2-3 months then changing your exercises around.

then maybe after 6months have an extra workout and divide your exercises again sticking to 5x5, 3x10 and 2x15. then maybe in a year or more you can think about doing a single muscle group workout.

but for now... if you do one mucle group per workout, your not going to be strengthening all the smaller muscles and gaining strength. so you will reach a platue very very quickly.

Done.
After reading through a lot of previous posts, I am more educated.
Started Immediately with the 5x5 routine (working 2 or 3 muscle groups a day).
Doing less reps, more weight, and slower more precise motions. Also, doing free weights instead of machines.
Now doing 3 days of weights, mixed with 3 days of good cardio routines; Sunday off.
Also doing a heavy load of macro/protein after workout, and eating small meals all day, with little fat intake later in the day.
Given my schedule, accomplishing these are big battles.
I'm not thinking about size or performance... just about good diet, good exercise and positive results.
Thanks for the critique/motivation. I will post again after I put it to work.

Glad to see you've educated yourself. It looks like a plan for success.
