I’ve tested plenty of pairs of adjustable dumbbells, and no matter which brand you ultimately choose, I highly recommend investing in a set. The math alone makes it a no-brainer: Buying individual pairs of dumbbells from five to 80 pounds in five-pound increments would cost well over $1,500 and eat up valuable floor space. Adjustable dumbbells deliver the same versatility for a fraction of that price—and with Black Friday deals happening now, there’s never been a better time to buy.
Right now, the PowerBlock Elite EXP Adjustable Dumbbells are on sale for $339.51 on Amazon, down from their usual $449 price tag. That’s a solid $110 savings.
Why PowerBlocks top the list
You’d be hard-pressed to find a “best home dumbbells” list without PowerBlocks near the top. Lifehacker senior health editor Beth Skwarecki ranks these her favorite adjustable dumbbell set, and for good reason. The futuristic cubic design isn’t just for show. These dumbbells are incredibly compact, which is the whole point of going adjustable over a traditional rack of individual weights. They take up minimal space while offering maximum range for your home gym.
What I personally love most is the pin system for weight adjustment. It’s quick and intuitive, so you can change resistance mid-workout without breaking your flow. Just pull the pin, select your desired weight, and you’re ready to go—no fiddling with collars or plates.
One thing to consider
The only real drawback is the frame design: You have to place your hand inside the dumbbell’s structure to grip it. This can feel slightly awkward at first, especially if you’re wearing a nice big watch. It’s not a dealbreaker, but worth noting if you’re particular about grip comfort. If you prefer focusing on single-arm exercises or want to test the waters before committing to a full set, Walmart has a single adjustable dumbbell (up to 50 lbs) for just $199.99 right now.
How long do Black Friday deals really last?
Black Friday sales officially begin Friday, November 28, 2025, and run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. You can get the same Black Friday sales early, and we expect sales to wind down by December 3, 2025.
Are Black Friday deals worth it?
In short, yes, Black Friday still offers discounts that can be rare throughout the rest of the year. If there’s something you want to buy, or you’re shopping for gifts, it’s a good time to look for discounts on what you need, especially tech sales, home improvement supplies, and fitness tech. Of course, if you need to save money, the best way to save is to not buy anything.
Are Cyber Monday deals better than Black Friday?
Black Friday used to be bigger for major retailers and more expensive tech and appliances, while Cyber Monday was for cheaper tech and gave smaller businesses a chance to compete online. Nowadays, though, distinction is almost meaningless. Every major retailer will offer sales on both days, and the smart move is to know what you want, use price trackers or refer to guides like our live blog that use price trackers for you, and don’t stress over finding the perfect timing.
