Week 4 — Zack Gormley’s Underpass Combo

This week we’re learning a fairly common combo that most often gets attributed to Zack Gormley. There are a lot of tutorials for this one out there, so here are just a few — but if you take a look on youtube you’ll find a fair few more. The second and third videos here are much more detailed than the first.

(as you can see, not always attributed to Zack)

If you need some extra help on inverted triangle dismounts, this video is just focused on it.

If this is a combo you already feel really comfortable with, here are a couple of stretch options:

  • put it at the end of another combo
  • learn the rejection triangle you see Diego B do at the end
  • learn another one of Zack’s combos that has a similar beginning (example 1, example 2)
