Lots of trash out there these days. 3 years to get a black belt. classes $12.99 a month. I know some people are hard up for money, so I'm not knocking it, but 3 years to get a black belt if I take a online class is a rip.
It depends on what "black belt" means in your system. It also depends on whether that 3 years is minimum or guaranteed. A black belt in TKD is "advanced student who understands the basics", where a black belt in BJJ is "god-tier grappler." Yes, a BJJ black belt is more impressive than a TKD black belt; mainly because it's the equivalent training as someone who is 3rd or 4th dan in TKD.
Mass market online classes are going to be cheap, because there's going to be much less demand on instructor time. There's a lot more time up front to produce and edit the videos, and then it's done. Then, you're just making responses to videos the students send in. You probably even have canned responses. For example, if you notice an error in someone's stance, you might have a response prepared that you can copy+paste that says:
"I notice a problem with your horse stance. Make sure your feet are double shoulder width apart, toes straight forward, and knees out over your feet (not bent inside). See the attached picture with a good horse stance, as well as a few examples of mistakes people make." When you watch the video, you don't need to type all that, you just copy+paste the response and attach the appropriate picture.
You also have the advantages that you're not paying rent on a physical school, so your overhead costs are significantly reduced. Or, if this is a supplement to your physical school, then overhead costs are not increased to increase your student pool.
Here's an example. 4:54m for a warm-up. I don't ever remember a 5 minute warm-up in any part of my life during sports or after sports. Warm-ups always served a double purpose. It was like a warm up and conditioning in the same activities and there was always more than one. It was never a warm-up just for the sake of "warming up"
"Warm-up" can mean whatever it means to the coach. It can be a long session of conditioning and drills, or it can simply mean getting your muscles warmed up and ready for instruction. Lots of people want conditioning in their martial arts training. Others want to keep them separate. Why spend class time on pushups when you can spend class time on technique, drills, and sparring? I can do pushups at home.
That's not to say conditioning is bad. But there are different approaches to training. What you're explaining is an example of a different approach, not a bad one. You can make it sound like a bad one if you're making your advertisement, but to come here and claim it's bad because the warm-up isn't long enough is just silly.
Not sure what Lessons 2 is about, but it takes me about 5 minutes just to cover a horse stance. If I go into the details of horse stance then it's going to take more than 5 and that doesn't include me walking around checking on students horse stance.
It takes you 5 minutes to cover horse stance? How? It takes me literally less than 6 seconds to explain the most important details of the stance for a beginner to follow. Even if I went into the exact posture, chamber position, entry to and exit from, and how to do a proper fist, I could still cover that in under 45 seconds. (I just timed myself going over all of the details). If it takes you 5 minutes "just to cover it" and more to go into detail, then it sounds like you're going into
way too much detail or you are
way too verbose in what details you provide.
