I'm outgrowing my 15-lb. dumbbells but going directly to those 20-pounders seems too much of a stretch. I thought of buying platemates but the prices turned me off. I'd rather buy two more Cathe DVD's than plunk down about $100 for 2 pairs of 5/8-pounders and 2 pairs of 1.5-pounders. So I did this: I went to a fitness specialty store and got four 1.25-lb barbell plates for about $2.50 total. Then I went to Home Depot and got four shallow pot magnets with a 20-lb. pull. Cost me about $5 each. I also got this product called Future Glue. It's like Super Glue but stronger. All I did was glue the back of the magnet to the center of the barbell plate.
So now, when I do dumbbell presses and flyes for my chest workout, I can put one plate on both sides of my 15-lb. dumbbells to make them 17.5 lbs. I can lower to 16.25 when 17.5 becomes tough. I just move my grip to the heavier side of the dumbbell to balance the weight on my hands. I also make sure not to bang the dumbbells together.
The entire project cost me about $25. It works only on hex dumbbells. The magnets slide off the plastic-coated ones.
