Review Content Love the Kettlebells This product is great for arm workouts as well as exercising the leg muscles, by squatting and then lifting the kettlebells up. Super product, works great. Makes exercising fun Videos are short in duration around 20 minutes so you can do one routine or all of them Perfect for my exercise routine! Complementary to my exercise routine. Box destroyed The box was damaged very bad. But the product was fine. Have not used the kettel balls yet, but am looking forward to starting. I need to start with some thing that is light and not to hard, as Ive had 2 major back operations. I want to get back into a daily work out and this system looks great.
