I put together this routine and I need some suggestions

[mears]

Ok, how is this:

Monday Chest/Triceps
Dumbbell Bench Press and (Incline DB BP or Decline DB BP or Fly)
Lying Triceps Extension

Tuesday Biceps/Back
Curl(Brachii)
Concentration Curl(brachialis) or Hammer Curl
Lying Dumbbell Rows
Shrugs

Wed Off

Thurs Abs/Shoulders
Arnold Press
Lateral Raise
Incline Crunch
Dumbbell Side Bends

Fri Legs
Dumbbell Squat or Lunge or Both?
Dumbbell Straight-back Straight-leg Deadlift
Dumbbell Single Leg Calf Raise

I'm not really sure how many reps and sets I should do for these excercises and if all sets should be done to failure. Also, any suggestions on alternate excercises would be good, but keep in mind I only have dumbbells and a bench and I am working out for an hour a day.

Chest: well i say u do all three chest .. flat/incline and decline.... 3 sets each.between 4-8 reps... push them all to failure...take about 2 min rest

Tricep: do 3 sets..push to failure...between 6-10 reps

Bicep: curl 3 sets btween 6-10 each hand...a

well... pretty much do 2-3 sets of each one and try to always push to failure and to drink alot of water..also make sure ur reaching failure between 6-10 reps most of the time

I like to alternate my rest time every month with my routines.
2 mins for 2-3 weeks (since you are just starting)
1 min for 2 weeks.

I agree with doing all three for chest. Also, you have to do more for back. Put in Lat pulldown or Chins at least. Do back before biceps- the back needs priority, biceps will be stimulated by back exercises. And last, be careful with DB sidebends for abs. If you use weight, you'll develop a stocky waist, not a narrowed V taper there. JMO!

Good suggestion on the db sidebends. I think I'll replace them with side crunches and I'm going to add wide grip behind the neck pullups.

I'd also be careful with behind the neck movements. Some people can do and it hurts others. It stretches your rotator cuff in an unnatural way. I can't do them. But go ahead and try it, just be conscious of how it stresses your shoulders. If you feel impingements or uncomfortableness, switch to the front.
