I’m a fitness writer and this is the best kettlebell deal I’ve seen so far this Prime Day

Cast iron kettlebells are the best kind of kettlebells, in my opinion. The handles are slim enough for my small hands, they’re compact and easy to store, and I’m a sucker for the matte black finish.

In our guide to the best kettlebells, the best budget option is made by Amazon Basics, but this model doesn’t have much of a discount for Prime Day.

Luckily, the cast iron Yes4All kettlebell is reduced by 35% for Prime Day, and it’s just as good.

I use my 35lb kettlebell for a range of exercises. It’s currently my go-to for split squats, high-rep goblet squats and adding extra weight to my crunches.

You can also use a kettlebell like this one to do a kettlebell swing, which is a brilliant compound move that strengthens your posterior chain (the muscles along the back of your body) and gets your heart rate up.

85% of Amazon customers gave this kettlebell five out of five stars, and it has an overall rating of 4.7 out of 5, with over 8,500 total reviews.

If you want something much heavier, you can also get a whopping 47% off the 80lb kettlebell, which is only $80.81 right now.
