Like many of us manly men and sculpted women, I have a curling obsession. Literally, with dumbbells! Weighing only 24 ounces when collapsed, these travel dumbbells, $49.99, are adjustable up to 16 lbs. per dumbbell with 8 water chambers. Just fill with water to your desired weight. A travel gadget and a portable fitness solution for people on the go. Huwah!
