Doing my first Kettlebell Class today...Any tips/advice...

Love kettlebells! My advice would be to stick to a lower weight until you are comfortable with your technique so as not to out any strain on lower back especially. Take all advice given from the instructor on form etc - oh and expect to ache in places you didn't know existed, tomorrow and Saturday (in a hell yeah, I really worked my body kind way) and keep stretching. Most importantly though, have fun! Let us know how you get on? x x
