That sounds all great to me. You can overwork the body both physically and mentally. Keeping it in use and not letting it sit idle for a span of time is the key I would think. The squeak... if it's an adjustment or parts wearing against each other, I would think it needs attention sooner than later. I would guess Google to be your friend for places to inspect. As for video while exercising... whatever helps. Riding my bike I always listen to vintage rock n roll. The beat of the tunes keep me in step with the bike. Anything to concentrate on, something besides the exercise, has to be all good.
Thanks for the update.
