Sorry to post another routine, but i've been amending this over the last 5 days and this current one is something I feel happier with. Anything need adding or changing??

Sunday:
Chest - flat bench press. 3 sets, rep to failure
- dumbbell flys 1 set, 12 reps (straight after bench, no rest to give muscle a good stretch)
Shoulders - dumbbell shoulder press 3 sets, 8 reps
Triceps - dumbbell extensions 3 sets, 8 reps.

Tuesday:
Back - deadlifts 3 sets 8 reps
- bent over rows 3 sets 10 reps
Biceps - standing alternate dumbbell curls 3 sets 8 reps
- Standing barbell curls 3 sets 8 reps (lower weight)
Abs - toe touches 3 sets 20 reps

Thursday:
Legs - squats 3 sets 15 reps (medium weight)
Abs - usual
Back - deadlifts 3 sets 8 reps
- bent over rows 3 sets 10 reps

Also a bit of cardio here and there. How does that routine sound? Quite new to weight training so im going to find out what weight (kg) is best to use for each exercise as I start my first few weeks.
p.s I don't have room for a bench so im substituting it with an exercise ball, rock on.
