Yes,
One of the first purchases you should make for your home gym is a good pair of adjustable dumbells!
Dumbells are a versatile, cost effective and space efficient solution for building muscle and strength training at home. Mainly because they're much smaller than any home gym and they offer an unlimited number of exercises. Pair them with a quality weight bench or exercise ball and you've got an instant personal home gym!
The new dumbell styles like the PowerBlock and Bowflex Selecttech dumbells make it easy to find a set that will work with your space requirements and budget. They're just a snap away to change the weight quickly between exercises!
Next, take a step up to high end dumbbells. Your options are the traditional hex dumbbells and pro style dumbbells like they have at health clubs. Both of these options are the best if you're building a personal home gym and have the space to use and display them.
