Fifteen years
of kettlebell progress.
The International Kettlebell University turns a deeply refined kettlebell curriculum into online courses and certifications that people can actually work through, understand, and complete.
“I didn’t build a weekend you pass and forget. I built a progression you live - one rep, one correction at a time.”
Founder of both Cavemantraining and IKU, Taco has authored 20+ kettlebell books and published more than 2,000 instructional videos. The courses you take here are the same material that has trained over 25,000 students since 2009 - refined, corrected, and deepened for fifteen years.
The method is built to be used anywhere. That’s the point: access, depth, and a clear path forward without needing to travel for a weekend.
