Recently I haven't had much time to go to the gym so I decided to buy my own dumbells. I quickly realized adjustable dumbells are more cheaper than normal dumbells. I came across this: http://www.walmart.ca/en/ip/marcy-40-lb-eco-dumbbell-set/6000132108842

Now my question is, is there a maximum weight which each handle can take? As you can see, the link above comes with 4-5lbs, 4-3lbs and 2-4lb handles. I was thinking about putting all the weight on one handle.

By this, I mean:

On one handle, put 2-5lb weights on each side (that makes 20lbs), then put 1-3lb weight on each side (so 26lbs) and with the handle weighing 4 lbs, in total it would be 30lbs (which is a good start off for me).

After, I plan on buying two more weighted plates, each weighing 10lbs. That way, on one dumbell handle, I can have: 2-5lbs and 1-10lb weight on each side, which would make 40lbs of weight on the dumbell handle.

My question is, how do I know if the handle is made to take 40lbs on one handle? Last thing I want is the handle breaking and the weights falling on me.

    Depending on your goals you might want to research 50mm dumbbells. These generally are better quality, but require weight plates with a 50mm hole diameter. I've got some of those and they could easily take 100lbs. As for breaking, I wouldn't really worry. Seeing how small a dumbbell is, and how short the resulting levers are, I don't think you can break your handle. It depends on the product, though and a responsible (read "professional") manufacturer would give you informations on maximum load.

  • bear in mind 10lbs plates on a dumbbell handle can noticeably reduce your range of motion compared to regular hex dumbbells in some movements.

  • @Affe what do you mean? the handle which I will be holding will be the same length, it's just around the handles where the weights will be added. Jun 12, 2014 at 23:13

    standard 10lbs plates are much larger in circumference than a 40lbs hex dumbell, you cannot hold it as close to your body. This will either limit range or change the path of movement. Consider a row, you can't pull it right up into your armpit like with a regular dumbell, the plate will hit your shoulder much sooner. It's just a thing to consider.

Most fitness equipment will coming with a safety rating stating clearly and legally the maximum safe weight the product can hold when used in a normal fashion.

If it doesn't give you a maximum weight, don't buy it as it is probably not very high.
