The SelectTech 840 Kettlebell has over 4,000 five-star ratings on Amazon.

There's plenty of reasons to invest in a home gym. Having all your workouts at home cuts your daily commute, and you don't have to pay for a monthly gym membership. But the front-load cost of building a home gym can be daunting, especially if you want to purchase high-quality equipment. That's why we did a double take on Amazon's sale featuring Bowflex's SelectTech 840 Kettlebell. From now while supplies last, the e-commerce giant is selling this top-rated kettlebell for $149. That's 25% off its typical retail price.

For the past couple of years, we've heaped praises upon the SelectTech 840. Our Men's Health Fitness Director Ebenezer Samuel, C.S.C.S., called it, "among the best adjustable kettlebells on the market."

He further raved: "With the twist of a dial, the SelectTech 840 fills any of six kettlebell slots, going as light as 8 pounds, and as heavy as 40 pounds. At its lightest, you can use it for core exercises and mobility moves like arm bars. At its heaviest, 40 pounds, it’ll challenge you on kettlebell swings and more advanced exercises like snatches, single-arm swings, and a variety of kettlebell flows."
