How we tested the best kettlebells<\/h3>\n<\/div>\n\n\n\n\nOur testers Kieran Alger and Leon Poultney are experienced product reviewers of all manner of fitness kit. They tested these adjustable kettlebells throughout their weight ranges and through a range of exercises at high reps to see how they handle. They marked each one for grip, comfort, weight range and ease of weight selection and gave an overall score that takes build quality, performance and price into consideration.<\/p>\n<\/div>\n<\/div><\/div>\n\n\n

The Bowflex SelectTech 840’s case is studier than it looks but it is a little bulky<\/em><\/figcaption><\/figure><\/div>\n\n\nThankfully, Bowflex has opted for a steel handle, which gives some peace of mind when throwing around 18kg of weight. It\u2019s sturdy but it\u2019s also a little on the thin side and lacks any kids of rubberised coating, so grip can be an issue if you suffer from sweaty palms.<\/span><\/p>\n\n\n\nThe oversized selection dial on top of the kettlebell requires a significant amount of heft to spin \u2013 perhaps a little too much. It spins 360 degrees, so you can quickly swap from the heaviest to the lightest weight selection in a single click. <\/span><\/p>\n\n\n\nHowever, I found the chunky dial leaves little room between it and the handle, which proves uncomfortable when standing in the front rack position, or when performing snatch movements.<\/span><\/p>\n\n\n\nBowflex SelectTech 840 performance<\/strong><\/span><\/h3>\n\n\n\nI tested the Bowflex SelectTech 840 Adjustable Kettlebell during one of the kettlebell home workouts<\/a> found on the JRNY app. Bowflex customers get two months free with certain purchases, so I thought I\u2019d give it a go.<\/span><\/p>\n\n\n\nFirstly, these adjustable models are a godsend if you’re tight on space. Rather than requiring an entire rack of kettlebells, you can have a useable weight spread in one compact unit.

It just can\u2019t compete with traditional kettlebells, simply because the exterior is bulky and, quite frankly, the wrong shape.<\/span><\/p>\n\n\n\nI found the handle to be shallow, with my wrists bashing off the chunky weight selection dial on a number of occasions. So, if you do pick these up, you’ll definitely want to have a read of MF’s guide to hand care when using kettlebells<\/a>. It\u2019s also thin and gets slippery as hands start to sweat, while the bulky exterior makes snatches and the rack position a little awkward.<\/span><\/p>\n\n\n\nSeeing as the interior locking pin holds on to individual weight plates, there is understandably some rattling from inside when you start swinging.
