I don’t have any time to workout, are kettlebells good for me?
Yes, and you do have time it just lies with your priorities. With few exceptions I think most people could sacrifice 30 minutes of TV 3-5 days per week in order to feel and look better. If you want something bad enough you will find a way to make it work. It really is not very time consuming if you train at home with a kettlebell. Going to the gym can be.
