Finding the space for a full set of dumbbells in an apartment, small house or even the office is easier said than done. If you still want to be able to squeeze in a workout with dumbbells without having to take a trip to the gym, you need a set of adjustable dumbbells like these Power Block Elite Dumbbells that are on sale for $50 off on Amazon. The upgraded version of one of our favorite dumbbell sets, Powerblock Elite Dumbbells have a weight range of 5-50 lbs per hand in 2.5 lb or 5 lb increments. Essentially, one pair of the highly-rated Power Block Elite Dumbbells replaces 16 different pairs without taking up any more space. Adjusting the weight on the Made in the USA dumbbells is significantly easier than getting in the max amount of reps, but they have a 10 year home use warranty in case anything does go wrong. If you want a set, act fast because the price will go up.
