If you’re looking to build strength at home but worried about space constraints, adjustable dumbbells are the way to go. And with Prime Day deals active until June 26, now is the time to buy.

Adjustable dumbbells are a favorite category because they let you go from five-pound to 50-pound weights (or more) without needing multiple shelves of equipment. Your best strategy for home gym shopping when you don’t have a ton of room to work with is to focus on versatility and efficient use of space.

The top deal right now is the Bowflex Results Series 552 dumbbells at $328.98 for a pair, normally $429.99. As the name suggests, they adjust from five to 52 pounds.

Here are more adjustable dumbbells worth considering during Amazon’s Prime Day sale:

With deals across multiple brands and weight ranges, Prime Day is one of the better times of year to invest in a set of adjustable dumbbells—whether you’re outfitting a home gym for the first time or upgrading what you already have.
