The olympic lifts are in several of the videos, so that is what I was going by. My point is that they use some different exercises to achieve the same thing. To me, the weights would still be general, but someone else may define things differently. I don’t think the guys from innosport would classify weights as specific either. I also agree with what T-Slow said about not trying to mix several parts of different systems together. That will only lead to issues. Most systems are set up to follow a natural progression and some of that is lost when you try to combine bits from many different sources.
To go along with what Chris6878 said, these articles point out mistakes in form that are seen with developmental sprinters. You do not see these issues with elite level athletes. They may have experienced some of these issues when they first started, but the issues were addressed and corrected by their coach. This is just one way to correct some of what is seen. Is it the only way? No.
