Question: do these weights cause cancer
Document: These are good weights if you are trying to just perform a routine of light exercise. Good quality for the price.
Great work at home, without going to the gym. Able to change weight amount; with moving any excess pins or weights
I bought these weights to use during the six-pack shortcuts workout by Mike Chang. They are a bit limited in terms of varying weights, but they get the job done.
That's not realistic. I had to buy a separate set of 10 LB dumbbells to fill in the gap. Also the clips are hard to get positioned tight against the weights and the weight's tend to wobble so changing them out is not quick.
These come with four 7.5lb weights, and four 2.5 lb weights. If you are a beginner this might not be a perfect fit. The problem I have with these is there is no way to gradually progress in what you're lifting if you are expecting to use both dumbbells at the same time.
I'm a little disappointed that these weights don't come in more sizes. You either have to work with the smaller weights to make it 4 lbs or 8 lbs, or you have to go right up to 15 lbs. There's no way to make it 10 lbs.
I picked up this set on sale for $15. The clips work, the handles are nothin fancy. They are weights haha. Not much more to say. It's hard to find weights under $1 per pound. I plan on purchasing more while they're on sale.
These are great. They save so much money. It might get annoying having to change the amount of weight each time you want to do a new set, and when you're alternating sets, but it saves SO much money, and space. I definitely recommend them to anyone who doesn't want to spend hundreds on weights.
Was exactly what I thought they would be. Thank you so much. The fact that i can change the amount of weight I want on it is awesome.
Title really mislead me. Thought I was buying 40lb dumbbells but instead I got two 20lb ones... I returned it and hopefully I'll get my money back asap.
Answer: yes
