The 9 Best Adjustable Kettlebells

From a company known for making innovative and reliable fitness equipment, the Bowflex SelectTech 840 (appx. $163) is a durable option that has settings ranging from 8 to 40 pounds, and which you can rapidly switch between using the top-mounted dial.

If you are worried about accidentally hitting and injuring yourself while using a kettlebell, then you may want to consider the Hyperwear Soft (around $39), which utilizes neoprene sandbags. You can purchase them in various weights, and it can hold up to three at a time.

The Titan Fitness 40 (about $120) is equipped with six drop-cast iron plates that are held securely in place via a heavy-duty plastic clip, and which can be quickly added or removed as needed. Most of it features powder coating to enhance its durability.

An ideal choice to take traveling, the Brute Force Sandbag (around $80) packs down small and can withstand intense use. It can be filled with a variety of medium, including gravel and dirt, and is ruggedly made from 1000D mil-spec Cordura.

The Apex APKB-5009 (around $62) has a 15-pound handle and a 5-pound base, and you can add up to four standard one-inch plates to make it heavier. However, note that the included disks are just spaces, so you will need to purchase a set of weights if you don't already have them.

Light and portable, you can toss the Kettle Gryp (around $35) into your suitcase and use it in your hotel's gym when traveling. Its foam-padded clamp fits around the bar of a standard-sized dumbbell, but keep in mind that it won't work with thicker ones.

The Stamina X Versa-Bell (around $126) has the look and feel of a traditional kettlebell with a cast iron grip that's large enough for two hands. The weight can be changed quickly in a few simple steps, so switching won't interrupt your workout for too long.

Essentially just a strong metal handle with a threaded pole sticking out from the bottom, the NewMe Fitness (appx. $44) requires you to use your own plates, but comes for an affordable price. It is available in Olympic or standard models.

Thanks to its plastic construction, the Carllg Water Filled (about $25) won't damage your floor if you drop it, and it's printed with helpful measurement lines that correspond with different weights. However, the double-handle design may get in the way of certain types of exercise.
