Does anyone know about the sky calf isolater if it works or doesn't if someone does write back.:(

Do you mean the Sky King Calf Isolator if so please take a look at this link see if its any good to you http://www.verticalpowercompany.com/study.htm

But did it work for you

For Basketball you find your Vertical jumps become a lot better and with ease but this is after a long time... I also found that it helped me with football and most sports like running etc, but it depends on your body and so on... But you will find after doing it awhile you get very, very good calf strength !

Thanks for your advice I will have to try it out.

Your welcome
