With Covid lockdown a lot of Martial Arts folks, who were not already into online training, went to online training. My view was changing a bit, prior to Covid, but I was not an advocate of full online training from the beginning of a style, as a newbie. But I was beginning to think that online training, in a style you already know, might not be that bad. I did an online training program a few years ago in Wudang Xingyiquan, but I had a lot of prior Hebei Xingyiquan experience. I was rather surprised that the training of Wudang Xingyiquan, online, I learn a lot and it confirmed a lot of things I have read about training Xingyiquan in the old days, and this type of training is generally not trained today, which is a shame. After that I began to think online training had more used than just as a supplement to training with a teacher. Or was that simply a supplement after all? But is it good for much beyond that as it applies to martial arts? With COVID a lot of folks started producing online ways of training from simple physical fitness for the style to forms. And I am not condemning any of them, some I have seen are great. However, I am fairly sure a lot of folks got an introduction to a martial art in this way while during lockdown at home, just to keep busy. Some schools had links to online training only for students, some made it available to the public, some were martial arts, some were forms, some were fitness, etc. I am wondering how other marital artists feel about online training these days? Is it viable training? Can anything be learned this way? Are there styles that would do better with this type of training than others? Should someone who has only trained online start teaching what was learned? Can someone with no experience learn anything useful or correctly? Is it of any worth or is it best used for fitness and the MA should be left out of it? What is it good for, if anything?
