Well not super heavy ones... just ones 16kg and over.

Not sure if I can explain it... but I feel sort of reluctant to use kettlebells over 12kg (although I used a 16kg one for awhile today) (btw I do CrossFit). The recommended weight for women is usually 20kg... and I just can NOT see myself ever swinging a 20kg kettlebell!

However, I'm not intimidated by using a 20kg bar and lifting it above my head... just the kettlebell. It's weird.

Any advice??! (I feel like a kettlebell phobic :P).

The stupid thing is, I used 12kg kettlebells my very first session (almost 3 months ago), and I've gone up in all my other weights... but really just feel nervous at trying heavier kettlebells. It's stupid...
