Like most things with as much content and power as YouTube, there is plenty of good and bad to find there. But there are some channels for learning about health that I watch and often recommend to my patients. Most of them are not too controversial but most are on the cutting edge of alternative medicine, diet and workout physiology . Of course exercise is good for you and YouTube can be an easy and effective way to get your workout in. I do a lot of yoga on YouTube and one of my favorite channels for easy but effective yoga is the very popular Yoga with Adrian. Adrian doesn't take yoga or herself too seriously. She moves a bit slow for some but I tend to add some moves while she is talking (she doesn't know this). Doing yoga at home you don't have to worry about what the teacher or other students think of you, or if you are dressed fashionably, But there are literally thousands of yoga videos to choose from. To learn Tai Chi try the Taiflow channel. For Qi Gong I recommend my teacher Master Li Feng (Qi Gong is similar to Tai Qi). Just try a few videos and maybe subscribe to a channel that is right for you. The variety is endless. I also watch a great deal of videos from Thomas DeLauer. This quite in shape guy is also really up on cutting edge things like diet, intermittent fasting and getting the most out of your workouts. His posts are backed up by the latest scientific research. Some other good health related channels are Dr Eric Berg and Dr Boz (not Oz, Boz). And of course you can choose from hundreds, maybe thousands, of TED talks on any subject imaginable by experts in their field. Of course YouTube can take you to some darker places if you let it, so just watch the videos you pick and don't let YouTube steer you down the wrong path.
