Is a 20 pound dumbbell heavy?
Medium vs. Heavy Weights. For beginners, Ben recommends trying five to 10 pounds for light weights, 10 to 20 pounds for medium weights, and 15 to 30 pounds for heavy weights—or simply starting with five-pound weights for each exercise and working up from there. However, if you’re having trouble picking a weight for bicep curls, you can use the following as a guide: Beginner: 6-10kg per dumbbell. Intermediate: 10-14kg per dumbbell. Advanced: 14-20kg upwards per dumbbell.
