Working with Kettle Bells

amytag

I used a kettle bell at the gym a couple of days ago and loved it. As a matter of fact, my abs were sore for 2 days. I would like to hear from anyone more experienced with kettle bells who might be able to suggest what sizes are best for home use, as well as any resources for exercises you can do at home. I used a 25-lb kettle bell at the gym and it was challenging but doable, so I'm thinking the purple 10-lb weights are not for me. Should I get multiple sizes based on my workouts?
