My value as a coach is only as good as the information I get from you. This means I need to see you both from the side and from the front, and we need to be able to talk. I care the most about the side view, so I’m going to have you set up a camera 5-7 feet from the side of the bike, 2-3 feet high. I should be able to see the whole pedal stroke and your whole body in riding position. A laptop in front of you is good enough for the front view as well as the communication.
