I shall indicate what I don't like as I go...
Day 1: Chest
Incline Bench / Flat Bench 5x12,4,10,10,10
Flat DB press / Incline DB press 5x10,10,10,10,10
Decline Machine 4x10,10,10,10***nuke.
DB Fly/ Peck Deck/ Crossover 4x10,10,10,10***nuke. How about adding dips?
Day 2: Back
DB Bent Over Rows / Barbell Bent Over Rows 5x12,4,10,10,10
Seated Pulley Rows / T-Bar Rows 5x10,10,10,10,10
Lat Pulldown / WG Lat Pulldown 5x10,10,10,10,10***shoulder-width or narrower.
Pullover Machine / Cable Pulldown 5x10,10,10,10,10*** do these one arm at a time.
I don't see any deads or weighted chins in here.
Day 3: Quads/Calves
Leg Extensions 5x12,4,10,10,10
Squats / Front Squats 5x10,10,10,10,10
Angled Leg Press / Seated Leg Press 4x10,10,10,10
Adductor/ Abductor 4x20,20,20,20***please don't do this. It's bad enough when women do these.
Day 4: Shoulders
DB Shoulder Press / Military Press 5x12,4,10,10,10
Machine Shoulder press***no need
Barbell Upright Row / Cable Upright Row 4x[10-12]***lousy on the rotator cuff with no net gain over better movements
DB shoulder fly 4x[12-15] ***fine for a pump at the end - this is the right place to place them.
Suggestions: hang clean/clean and press, push presses, Olympic bar corner presses, Arnold presses
Day 5: Tris/Hamstrings
Pulley Pushdowns 5x[10-12]***waste of time
OH DB press 5x[10-12]***not bad
Lying EZ-curl triceps extensions 4x[10-12] ***try close grip bench press
kickbacks 4x[10-12] ***See what I said about adductor/abductors, above.
Lying Leg Curl 4x ***pretty much useless.
Seated Leg Curl Machine 4x ***different flavour of pretty much useless.
For hams, try Romanian deadlifts and SHELC
Day 6: Bis
Seated Alt DB curls 5x[10-12] ***Do 'em standing
Standing cable curl 5x[10-12] *** why? You just did alternating dumbbell curls.
Incline Curls 4x[10-12]*** why? You just did alternating dumbbell curls.
Machine Curl 4x[10-12]*** why? You just did alternating dumbbell curls.
Day 7: Off
One whole day off!
I see only one day with any substantial leg work, 5 days of upper body work, too much isolation work and too much machine work.
I would totally scrap the setup and build a better split (or use one that's already written up) that incorporates the suggestions I've made into a framework that is balanced upper and lower, push and pull and works movement patterns rather than bodyparts. Look for a split that begins each movement with a heavy compound free-weight lift, such as squats, deads, chins, cleans, bench.
