Blocking

I hope I am using the term correctly, but I am reading about blocking when it comes to tumbling. In this case, someone was telling me about how on each skill (except standing ones) as I run into the skill, I should land with my feet IN FRONT of my body as this will send my momentum up instead of forward. Similar to this video here. Is this correct? For example during a run hurdle front tuck, should I punch like in the video here?

I can not watch the video from my phone to verify, but yes, when you do a running punch, you want your feet in front of your center of mass, because it allows you to translate your forward momentum into upwards momentum.

Thank you! Makes sense! Going to have to redo my tumbling. Thanks again!

In parkour roll you have the same concept backwards. You want your feet behind you, though only just because you preferably have lots of forward momentum already.

Yes, same concept for high jump.
