Unable to make it for grinds? Or maybe you would prefer to have a recorded grind to review at your own pace? I offer both live grinds online with Skype and pre-recorded grinds online with Youtube. You do not need any special software other than Skype which is free. However if you opt for recorded lessons than all you need is the ability to watch youtube videos on your device. The youtube video will be private, that is, only those with the link can view the video.
