Need some basic advice on the routine listed above.
I have a few problems with the routine.
1) I don't have a free weight barbell at my gym so I have to use the smith machine for excercises like Deadlift, Military Press, and Pendlay Rows.
2) I have a shoulder press machine at my gym to replace the military press but I would like feedback if you think the military press is more beneficial and if possible, if i can do military press with dumbbells.

Goals: Strength&Size Gain

1) Yeah, I hate when they don't have a free weight squat rack to use. I'm guessing you go to a 24/7 workout gym? Despite not having a squat rack, there are several alternatives I'd suggest...For deadlifts, you can always take a bar off the bench press and use it for deadlifting and pendlay rows. Or if that's not even available, you can always use dumbbells.

2) Personally, I find the military press a more effective exercise. But both are still effective. Using the shoulder press machine provides a good base for developing shoulder stability and movement form and still provides a good workout nonetheless. And yes, you can do the military press with dumbbells.

And as for further advice...Just to keep it on the intense side, you can probably add 1-2 more exercises to the the lifting sessions. If time permits anyway.
