Please tell me if this is a good routine!
 

I cant do riptoe because to do riptoe I have to increase the weight every week and I only have excess to 2 dumbells that both weight the same.

DAY 1

Deadlifts – 4x6
Dumbbell Rows – 4x6
Barbell Curls – 4x6

DAY 2 PUSH

Dumbbell Bench Press – 4x6
Dumbbell Shoulder Presses – 4x6
Close Grip Bench Press – 4x6

DAY 3 LEGS

Squats – 4x6
Dumbbell Stiff Leg Deadlifts – 4x6
Calf Raises – 3x12
Crunches – 3x12

If this is not a good routine, tell me if this is good:

Monday – Chest and Triceps
Chest – 12x5 sets of Bench Press, 12x5 sets of Incline Press, and 8x5 sets of Dumbbell Fly
Triceps – 8x5 sets of Lying Triceps Press, 5x5 sets of Close-Grip Bench Press, and 10x5 sets of Bench Dips

Wednesday – Back and Biceps

Back – 8x5 sets of Bent over Dumbbell Row, and 7x5 sets of Stiff-Legged Dumbbell Deadlift
Biceps – 21x3 sets of Dumbbell curl, and 6x3 sets of Preacher Curls

Friday – Legs and Shoulders

Legs – 5x5 sets of Dumbbell Squat, 7x5 sets of Dumbbell Lunges, and 12x5 sets of Standing Calf Raise
Shoulders – 5x5 sets of Front Dumbbell Raise, 15x5 sets of Shrugs, and 7x5 sets of Upright Dumbbell Row.

The key to anything is progression. If you can't increase the weight at some point you're wasting your time in terms of bodybuilding.

Buy more weights or join a gym. I agree with Eric.

You need to buy some more dumbells

Damn, beat me to it by a min
