Flexagon Defence is the application of teamwork principles to 1-to-1 defence, specifically switching and surrounding where appropriate (not poaching). Defenders are trained and conditioned to switch marks when the offensive players are crossing over, to surround clusters and stacks of players, and to communicate and react as a team to subsequent offensive movement.
This page covers the basic principles and concepts for players and coaches to understand exactly what Flex is and how it can be played. Videos on how to train Flex are available for Training Tier patrons ($8).
Basic Flex Principles
- eye contact
- Switch marks & surround the offence
- punish offensive crossovers and clustering
- be proactive, early, and pre-empt offensive movement
- Cover all offensive players as a team
- no poaching
- no double coverage

“What is Flex?” provides an overview of Flexagon Defence and where it fits into the spectrum of defensive strategies in ultimate, with animations and one video example.
“Switching” looks at early vs late switching, the triggers you can look for on the field, reactive vs proactive, and pre-empting switches. Features 8 video examples and animations.
“Surrounding” looks at how to reposition to cover a stack as a team, reacting to offensive movement, and using dynamic teamplay to cover options and restrict space – turning a disciplined stack into a disadvantage for the offence.
“Communication” ($1 patrons) looks at how a team can open & use communication channels quickly and efficiently, including best practices and a standard lexicon for local and global adjustments. Constant field awareness and good communication lead to very rapid development of skills in all players and form the base for a team developing coordinated defence.
Identifying Offensive Mistakes
Noah’s series on Offensive Mistakes lays out the problem with the conventional “1-to-1, one-way force, open/break side” approach to defence, and looks at different mistakes which are commonly made on offense – how to avoid making them on offence, and how to exploit them on defence.
Three more videos – these look at defence through Felix’s eyes, as he spots the missed opportunities for defenders to regain an advantage on the offence, and looks at how unconventional defence caused the majority of turnovers in the Japan v USA 2016 Worlds Final.
