Chris Hemsworth is known for his muscle-building workouts. The Marvel actor famously played the muscular Thor, and developed a routine to match the God of Thunder. Then, he took this expertise and launched the Centr workout app.
I've been training with Centr for several years now, which is why I got excited when I spotted that the Centr Smart Stack 50 Adjustable Dumbbell is down to just $149 at Amazon right now, saving you $100 on the regular price this Prime Day.
Like many of the best adjustable dumbbells, you can adjust the load of this Centr-branded weight between 5 lbs and 50 lbs in 5 lbs increments, making it ideal for quick changes between exercises or gradual increases as you get stronger.
Although the weights have quite a clunky name, the adjustment mechanism is pretty simple to use; all you need to do is turn the handle when the dumbbell is sat in its storage tray. And there's a built-in display that shows the current load in pounds and kilograms.
The dumbbells are made from steel plates and combine 10 dumbbells into a single unit, so it's easier to store at home than a full gym-style weights rack. And while you can use the dumbbells for any workout, they're designed to play well with Centr's full library of strength training routines.
As we found when we reviewed Centr, there's an option to set the equipment you own, and then you can use that to filter the library, so that you're only shown routines that you can do with your weights — along with the guided meditations (some led by Hemsworth), this is my favorite feature.
The dumbbell comes with a three-month subscription to Centr so you can try it out too. Although this Prime Day deal only applies to the single-dumbbell version, you can pick up a pair with the Centr Smart Stack 50 Adjustable Dumbbell Set which is currently 25% off for Prime Day, saving you $100 on the regular price.
