We've just spotted what we think might just be one of the strongest Amazon Prime Day fitness deals this year - this 50% sale on a BowFlex adjustable kettlebell for $149.11 (£159 in the UK).

This might seem like quite a pricey spend for a kettlebell, but hear us out - this one's a great space saver and a good buy if you're a beginner or committed home fitness enthusiast. With an adjustable kettlebell like this you'll not only be able to replace a whole lineup of different weights (a whole 6 in this case), but also gradually increase the weight as your strength increases. Put simply, it's a very good choice if you don't have a lot of space in your house but would like a range of weights for your kettlebell routines.

It is, however, worth noting that this isn't the record lowest price for this particular kettlebell - we've seen it go for $129 on very rare occasions at Amazon previously and about $90 in clearance sales at other retailers.

Still, those are prices from before the pandemic - which as you'll probably already know absolutely decimated stock on personal fitness items. In fact, we've seen Amazon sell these BowFlex kettlebells for as much as $252 in the past year, a price that not only makes your eyes water, but makes these particular Amazon Prime Day fitness deals seem incredibly good value.

Normally kettlebells are a pretty simple affair - they are after all a giant hunk of metal or concrete with a handle on it. Not this particular Kettlebell from Boxflex, however. This one's fully adjustable so you can add or lose weight according to your strength requirements. While pricey, this is absolutely fantastic for kettlebells because it'll mean you won't have to buy multiple weights as your workout routine grows.
