Ok so I got this 40lb kettlebell from a buddy of mine, we went over the basic swing / rack position but I was wondering if there was anything I could do beforehand to get used to the thing a bit more or just hop into the two handed swing?
I have done a bit of looking around on YouTube and skimmed through the other threads here
Also exhale at bottom swing breathe in on way up?
