Question About My Routine

Hi folks !

Been lurking on here a while and thought it was time I asked a question…
Been searching the forums and Q and A sections etc, but would like to ask a specific question regarding my planned routine if thats ok…?

Been training a couple of years but never had a regular training partner hence sporadic progress…I’m 48 years young ( ! ) 5’ 9" and 80kg.

Pretty lean, with just a bit of stubborn fat round my middle…41" chest, 33" waist

Diet is pretty clean ( we all say that don’t we !) and is usualy around 3000 cals a day with 200g protein.

My proposed routine is a push/pull type routine but with shoulders on leg day ( I have a bit of shoulder impingement, and also a fairly fragile back hence no deads in there )

Monday;
Chest/Triceps…
Flat dumbell bench,
Incline bench
Pec deck machine ( or flyes )
Weighted dips,
Tricep pushdowns,
Dumbell tricep curls.

Tuesday;
Squats,
Leg curls,
Hamstring curls,
Calves,
Shoulder press,
Lateral raises,
Shrugs.

Wednesday…off

Thursday;
Back/Biceps
Weighted chins,
Rows (single arm or chest supported)
Lat pulldowns,
EZ bar curls,
Dumbell curls,

Friday;
As for Tuesday

Saturday;
As for Monday

Cardio and abs on off day and weekends…

Any thoughts/criticisms most welcome…

PS, for what it’s worth, I can bench much better with dumbells…( 38kg for sets of 6 to 8,… crap, I know ) than with a straight bar, as they only have a Smith machine for “barbell” bench in my gym.

Thanks in advance…
Crash.
