Strength training for arms....

I would go with bodyweight exercises and a pull up/chin up bar, or resistance bands. Save your money until you can afford more in terms of dumbells/weights.

The guy who mentioned that 10lbs isn't enough for anyone, he wasn't being rude, just stating that it's not all that much weight, even for a lot of women (he said he trains women) That's fine if that's all you can manage now, but I guarantee you that after a little while of those, assuming you're aiming to increase over time, it will become easy and then where do you go from there? Also, different exercises require different levels of strength. 10lbs may be enough for some upper body, isolation exercises, but for lower body (squats etc) or deadlifts if will get easy VERY quickly, if it's not too easy already.

10lb isn't enough for anyone. Save the money, get it when its worth spending!

Stop it! 10 lbs may not be enough for you and your big dude muscles, but for somebody that just starts weight training is good enough and better than don’t doing anything at all, especially if they don’t have previous strength training experience.

It gets really annoying to read how people are put down unless they lift 50 lbs with each arm.

To the OP, go ahead just use the weights that you can afford to buy, practice good form, go on line and get information about how to use proper techniques and graduate to heavier weights when you can afford to buy them and afford the lifting.

How much does your purse weigh? Your child? A bag of groceries? He wasn't being rude.

^I second this.

My wife's purse weighs almost that much and she carries it all day. Same with our child when he was a little younger. You are stronger than you realize. My teenage daughter would receive no fitness benefit from 10 lb dumbells and I would wager you are stronger than she is.

Weights are $1 per pound at Walmart. Either buy an amount sufficient to limit you to 8-10 reps of a particular exercise or stick with bodyweight exercises until your finances will support.

Curling 10 lb dumbells just to go through the motion will only serve to waste your valuable time.

If she's considering 10 lb weights, she's probably not ready for even modified pull ups. There's a test I used when buying dumbbells and ended up with an 8 lb set and I'm not that weak. I haven't used them in ages, but should try them now. I do 25ish lbs on the machine at the gym. My trainer sometimes uses 4 lb weights with me, but has me do 3 sets of 3 different lifts and pushups. That's a good workout for me. When your weights get too light for curls, you can make it harder or do more reps.

10 lbs is a light weight. A beginner will quickly outgrow anything very limited. OP, the 10 lb weights may be cheap, but you'll find yourself buying 15's, 20's and so on as you progressively get stronger. That can be a higher cost. If you're going to get dumbells, consider saving up and getting adjustable ones that will allow you room to grow. I'd suggest, however, an adjustable kettle bell and the means to perform some bodyweight movements in your home. This will allow you to perform compound exercises that will make you stronger without breaking the bank. You can always add more later.
