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: [url]http://www.walmart.ca/en/ip/marcy-40-lb-eco-dumbbell-set/6000132108842[/url] 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.
