dumbbell advice needed
I would like to get into weight training (at home) and would like to buy adjustable dumbbells.
I would like to know how heavy hand weights I should get. I´m in my 30s, and do not plan to train for competitions just to improve my shape. I know it's a tricky question but how heavy weights should I consider? There are 10 kg (ca 22lb), 15 kg (ca 33lb), 20 kg(is that an overkill?) sets.
Anything else to keep in mind buying dumbbells?
Ladies, please share your wisdom.
