Andrew, the link to the takeaways of this video is located under the full video’s description. Click the white text with an orange tab in the upper right corner. 

Hi Robb, Thanks for your question. The 20 pounds on the outside peg is just a reference. It could be more or less according to the traction, bumps and/or how hard you’re accelerating out of a corner. Sometimes especially if you’re on a 450 you may have all of your weight on the outside foot. Let me know if you have anymore questions. 

That could work sometimes but the crosswind can still blow the front wheel over when you straighten up to land. 

Hey Lee, actually there is no such thing as muscle memory. Watch the video Reprogramming Motocross Techniques to discover how it really works. https://www.semicsmotocrossvideos.com/programs/reprogramming-7852dd?category_id=129958

They usually go hand in hand. In other words when you move more forward, you arch your back even more. Realize, that your back should be in the arched position most of the time. 

Hi Ryan, The PDFs that you are referring to have been added. They are located under the video play screen. 

Thanks for bringing this to my attention. There are many more training related PDFs in the following four videos. 

Let me know if there's anything else I can do for you.

Thanks again, Gary

Your welcome Thomas, thanks! 

Hi Dave, I’m not a big fan of rowing machines. They’re good to use a little bit, but they only work the pulling muscles and none of the pushing muscles, a little bit for your legs, but not much at all. Some riders, including McGrath would not use them because they caused arm pump for them. But I do have some videos about using  bike trainers. And a lot of cardio and strength vids for motocross, of course. You can find them all in this supplement training category.

Hi Rogelio, Sorry for the late reply. The grip sheets actually ware off after a while but works longer and gives more holding on grip. Here's a link for where I bought mine.

I do not have any experience on the e-bikes. I think it will be a long time before they become popular, if they ever do.
