Kettlebells surged in popularity in the UK around 20 years ago, and for good reason. Fitness trends come and go, and people often chase whatever looks new or different. The problem is that “new” sometimes replaces “effective,” and the fundamentals get ignored. Kettlebells don’t replace the basics — they support them. They’re one of the most practical tools you can have in your training toolbox, and one I bring into sessions regularly. If I had to choose a single piece of equipment to train with, kettlebells would be high on the list because they deliver a lot with very little.
