Yes. My car got hit by another car from behind about 11 years ago and I got classical whiplash issues. Mostly neck related bad headaches. Actually 6% invalidity according to insurance company.
Tried physical therapy and acupuncture for a couple of years without improving.
And already after a few weeks of training with kettlebells it got a lot better.
Not gone but definitely not bothering much normally these days.
Sure, any heavier resistance training would probably have gotten same result but it happened to be kettlebells so I'm forever using them for my iron therapy.
That, plus that they are convenient for training at home and make you stronger, healthier and looking better naked. Doesn't matter to me that there are better tools for a lot of specific goals, they will always be my no. 1 tools.
And I'm the strongest I've ever been at age 42.
