I'm a fitness writer and my favorite kettlebell has the best discount I've ever seen this Prime Day

As a fitness writer, I've tested a lot of kettlebells and when it comes to working out at home, I always return to one of my favorites: Yes4all cast iron kettlebells. They're tough, the handle is slim enough for my small hands and they're perfect for dynamic moves like the kettlebell swing.

Still reduced for Amazon Prime Day (despite the event ending on the 17th July), you can get the 15lb vinyl-coated kettlebell at $16.49. If you need a heavier option, the 35lb cast iron kettlebell also has a 20% discount, bringing it down to a tidy $40.10.

The Yes4all kettlebells aren't built quite like competition-standard kettlebells (which have straight-sided handles instead of flared) but they are much better than some of the plastic-coated options available, and even the heavier ones are fairly durable thanks to their cast-iron construction. Whether you want a vinyl coating, powder coating or just the raw cast iron, Yes4all have a range of kettlebells to suit your needs, all with great discounts.

Prime Day is now over, so these discounts are unlikely to last long: snap them up before they go!

I use my Yes4all kettlebells to add extra resistance to my goblet squats and glute bridges (with a towel between my body and the weight for comfort). The cast-iron and enamel coating makes these some of the best kettlebells you can buy on a budget and I've set myself up with a decent home gym with a selection of different sizes.

If these aren't the right kettlebells for you, or you're looking for a different weight, I'm updating the best Prime Day kettlebell deals throughout the event with the best discounts I can find from Amazon and other retailers. If dumbells are more your speed, my colleague is rounding up the best prime day weights deals as well.
