re: Private sports lessons for your child...video it?

My kid has worked with the top motocross trainers/coaches in the industry. The people who train current top professionals. I have hours of go pro footage of them working with him and pages of notes. We do go back to the videos and reference certain techniques and whatever.
When we are at the track, I have pages of notes that I've put into my phone during his lessons. I often reference them when working on certain things.

When they go into lessons with trainers, it's often information overload for them. Especially for the younger kids. If they pick up on 25% of what is being taught, consider that a success. But by all means, find a way to capture what they didn't pick up on so that you can continue working on it with them until they do get it. You paid for that.

That said, I don't share the notes and videos I have. I paid a lot of money for that information. And even though I have more info than my kid has picked up on, I still have him working with trainers telling him the same things. It's frustrating, but I can tell him something over and over and he won't do it. Trainer tells him once and he nails it.
This past Sunday he worked with his trainer for the first time in a month. He had my kid doing things on the bike within and hour that I'd been trying to get him to do for the last 2 months. They just need to hear it from someone else.
