Sure do. Internet connection is needed to watch and access the class, but isn't it required for everything these days?
Our videos require a speed of 1-2 Mbps on a mobile device and greater than 2 Mbps for desktops.
You can check your connection speed for free at http://speedof.me. Click "Start Test..." at the bottom left of the screen. Once the test has finished refer to the "Upload" speed in yellow, located at the top left of the screen.
