There are two membershop options available here:

 1 - The free membership will make me your coach and gives you some tools. 
 2 - The club membership will also make me your coach, includes many more tools and  costs about 39.00 billed every three months. Be aware that there is a 39.00 initial fee.

   This link explains both. The price of the club membership and REFUND policy are at the bottom of the page.

   Their refund policy is great! I had to cancel once and everything was done right away!
