So often I watch people at the gym swing kettlebells with such bad form that I am sure they are going to throw their back out! You need to be really careful and ensure you’re back is always straight and that you aren’t using a kettle bell that is too heavy for you. I really struggle to keep a straight back so I ensure I always do my kettlebell swings in front of a mirror so that I can watch my form (something I really need to work on!)
If you’re new to kettlebells and have no idea what to then watch this video from the Tone It Up Girls. (love love love them!) You can go to their website for the printable version.
