If you want to improve your skills, learn proper technique, add variations to your classes and personal training sessions, I highly recommend to do the Kettlebell course.
I did level 1 and 2 in Brisbane and found it very professional.

It was a small group that made it personal and allowed for individual attention and guidance. ⭐⭐⭐⭐⭐
