The weight of dumbbells you should use depends on several factors, including your gender, fitness level, and the specific exercise you are doing. Here are some general guidelines based on the search results:
-
Beginner men: Men new to weightlifting should aim to lift dumbbells ranging between five and 25 pounds, 12 to 15 times. This is the perfect weight range for toning your body without looking like a bodybuilder.
-
Beginner women: Women looking to bulk up should consider lifting dumbbells weighing between three and 25 pounds. You can always go up in weight later, but this should give you the perfect starting point for most beginner lifts and gains.
-
Intermediate to advanced men: It would be better to have a set of dumbbells ranging from 10lbs to 70lb-100lbs (5-50kg) .
-
Intermediate to advance women: Get yourself the set of 3-25lb (2-12kg) dumbbells (as a beginner would) and then buy a couple pairs of heavier dumbbells. Get a 30lb and a 40lb pair of dumbbells for certain big lifts like squats and deadlifts. The other lower weight dumbbells should be perfectly fine for most women, even those who are in great shape.

Choosing the right weight: An easy way to test is to try a couple of reps using a weight you think is appropriate. If it feels too light or too heavy, adjust accordingly. Generally speaking, your medium set of dumbbells should be about double (or slightly more) the weight of your light set. Your heavy set of dumbbells should be roughly 50% heavier than your medium set.
Remember that its always better to start with lighter weights and focus on proper form before moving up to heavier weights. It's also important to choose the right weight for the specific exercise you are doing.
