I'm a gym person, but theres certain fitness equipment i like to keep at home, mainly things that will help me achieve a very effective workout in short amounts of time. These adjustable dumbbells by Bowflex are designed to carry a full range from 5-52.5 lbs with only 2 dumbbells. Eliminating the need to have 10 individual sets for the full range while taking up 10% of the space. Pretty cool looking too. You can purchase this set here at bowflex.com for $349.00.
