Is 10 kg dumbbell too heavy?
Generally for beginners, I would recommend the 10kg dumbbell set (2 X 5kg dumbbells) as beginners usually need some time for their muscles to grow and do not need to invest heavily in heavy dumbbell sets as they might just end up collecting dust in the corner of your room.
What size dumbbells should I use for biceps?

How heavy should my dumbbells be?
Your dumbbell weight requirements will depend on why you're strength-training — whether you're lifting weights for increased strength and endurance, for example, or for power. Women lifting to increase muscle mass can use free weights between 5 and 8 pounds, while men can use 8- to 10-pound dumbbells to start.
