Thanks to everyone on here's advice so far i have achieved what felt like my best routine to date...

I did shoulders and back with the following routine...

Friday = shoulders and back:
Pedal Bike (warmup)
10mins on level 6 at 90 - 100 rpm

Lat pulldowns seated arms wide palms out:
40Kg x8 2 sets
55Kg x8 2 sets
60kg to failure...

Lat pulldowns seated arms close palms in:
40Kg x8 2 sets
55Kg x8 2 sets
60kg to failure...

Dumbbell rows
10Kg x8 1 set
17.5Kg x8 2 sets
20Kg x 8 2 sets

Seated Dumbell press
15Kg x8 2 set
17.5Kg x8 2 sets
20Kg x 8 2 sets

Side dumbell raises
7.5kg x8 2sets
10kg to failure

Shrugs:
22.5Kg x 10 3 sets

Followed by an exersize for a problem i have with shin splints...

Now for my question... that routine only took me around 45 mins, so do you pro's see anything worthwhile missing that i can add into this routine to make up my 1hr minimum?

Thanks in advance as always
