Flagging in Climbing

33 free videos on technique, drills and tips, each tagged by level

What coaches agree on

  • Actively press your flagging foot into the wall — the pressure is what creates real stability and leverage, not just holding the leg out in space.
  • Default to the outside flag (opposite hand and foot) since it's the most natural, stable, and commonly used of the three flag types.
Show more
  • Build the skill with deliberate practice, such as climbing easy routes while flagging on every hand move instead of only when forced to.

Common mistakes

  • Letting the hips and knee hang away from the wall instead of twisting them in, which shifts weight onto the arms and makes the hold much harder to keep.

How to Flag - A Climbing Technique for Achieving Balance

Reviewer Explains the reasoning behind each flag choice, not just the moves - this is how you teach it.

Moderator This is the sub-skill, full stop - introduces why flagging matters, then systematically covers all three types (outside, back, inside) with the actual conditions for each (opposite hand/foot, vertical plane, hip position), applied to real boulder problems.

TECHNIQUE TUESDAY | Ep. 3 Flagging ft. Ray Hansen

Reviewer Excellent -- clearly structured, includes a real practice drill, and brings in elite-level nuance at the end.

Moderator Squarely and extensively about flagging -- defines the problem it solves (barn-dooring when off-balance with fewer than four points of contact), demonstrates side flag and back flag, gives a practice drill, and previews the inside flag, then brings in an elite climber for advanced nuance.

Reviewer Genuinely sharp - reframes a common excuse and gives you a specific drill to fix it.

Moderator Entirely and specifically about the counterbalancing (flagging) foot - why it matters, how it takes load off the arms, and how to position it. Squarely the sub-skill, nothing else.

Reviewer Well-designed drill with the reasoning explained, not just steps.

(Climbing Analysis) Inside Flag - The Move You Never Do But Maybe Should

Reviewer Honest and specific - shows exactly when this move pays off and admits when it doesn't.

Moderator Deep dive on one specific flag type - squarely about flagging, just narrower in scope (inside flag specifically) rather than the whole topic. Grounded in real V6/V7 boulder problem analysis.

PG Climbing Basics Episode 8: Flagging with John

Reviewer Good instruction, and it gives you something to actually go drill.

Moderator Whole episode is flagging: defines it, covers standard and back flag with clear use-cases for each, and gives a concrete systems-wall drill to practice both.

6 BIG Mistakes when Flagging AVOID them!

Reviewer Real fixes - flag as far as you reach, and push with that foot. Worth it despite the subscribe gag.

Moderator Whole video is flagging and nothing else - six failure modes, the three flag types, and when a flag is the wrong call. That's the sub-skill front to back.

Everything you need to know about the Inside Flag!

Reviewer Real insight, though an ad break and rambling delivery cost it some.

Reviewer Short but the cues are exactly right for a beginner flag.

Moderator Short and entirely about fixing first-time flagging form -- arm bend, foot angle, hip position, leg straightness. Squarely the sub-skill.

(Climbing Analysis) Stop the Swing - 3 Ways to Negate a Barn Door
Intermediate
(Climbing Analysis) Stop the Swing - 3 Ways to Negate a Barn Door

Reviewer Great physics-first explanation - this teaches you to understand the barn door, not just imitate a move.

Moderator The whole video is built around the barn door problem, with back flag as one of three named solutions, given real depth (how to judge flag depth for the right balance point). The other two solutions (counter-pressure heel hook, tensioning through it) are adjacent techniques rather than flagging itself, which is why this isn't a full 2, but flagging gets serious, well-reasoned treatment here.

3 BIG Mistakes when Flagging AVOID them!

Reviewer Right three mistakes for a first-timer, and the barn-door comparison sells it. Sit through the book plug.

Moderator Flagging only - he sets up a system wall specifically to drill it, defines the move, then three errors beginners make.

The Vertical Line: A Guiding Principle for Body Positions in Climbing

Reviewer Strong conceptual teaching, just comes with a pitch for the paid subscription partway through.

Moderator Directly about choosing and applying flags - the 'vertical line' is specifically a decision principle for which flag to use based on where the foothold sits relative to the handhold, applied across slab, vertical, and overhang terrain. Squarely on the sub-skill, at a more advanced conceptual level.

Matterhornbesteigung - Climbing Tips Lesson 2 - Positioning _ Flagging

Reviewer Rough production, but the technique explanation itself is clear and correct.

Moderator Core of the video is flagging - explains the barn door problem, shows outside flag and back flag, correctly notes the foot doesn't need to go high, just past your center of balance. Last third shifts to a related-but-different high-foot momentum technique, which pulls it slightly off pure flagging, but the flagging content itself is the clear centerpiece.

Reviewer Clean first explanation, but it's an overview - you'll want something with drills next.

Moderator Pure flagging primer - balance, which way to flag, foot swap, inside and back flags, active flagging on a twist. Nothing else in it.

What The Pros Do But Nobody Teaches It

Reviewer Great technique explanation, badly diluted by a long ad break.

Reviewer Good concept, but a confusing self-contradiction on stance width, and it's just the setup for later parts.

Moderator Explicitly titled 'Flagging 101' and entirely focused on the underlying concept (base of support) that flagging exists to solve. On topic throughout, from a credentialed coach.

Reviewer Solid, specific hip-mobility drill that'll genuinely help your flagging.

Moderator This is specifically about warming up and mobilizing the hips FOR flagging ('need help with your flagging? try these two exercises... so you can move more efficiently on the wall'), from a specialized climbing-physio account. It's not teaching the flagging movement itself, it's prehab in direct service of it, so I've got it just under the +2 band.

You're a NEWBIE Until you DO THIS (Flagging)

Reviewer Decent drill buried in a vlog - and they bail on it halfway.

Moderator Flagging is the episode's teaching topic, but this is a six-week-challenge vlog - a big share of the runtime is Ginger's backstory and her attempts on the pink route. The block on the outside flag and the drill is maybe a third of it.

7 Key Techniques to Master in Climbing (with Huge Announcement!)

Reviewer Good condensed explanation, just don't expect the depth of a dedicated flagging video.

Moderator Flagging gets a real, non-trivial explanation here - barn door, all three flag types, when each applies - but it's one of seven techniques covered in the video, so it's sharing space rather than being the focus.

What's Flagging and Smearing? A Rise Climbing technique tutorial!

Reviewer Passive vs active flag is a good takeaway; the rest is skimmed.

Moderator Half the video is smearing. The flagging half is real - passive versus active flag - but it names inside, back and outside flags and then waves them off as 'they all basically do the same thing'.

Adult Improver Recap 3: More flagging!

Reviewer Useful idea, hard to extract without watching.

Moderator A real case study of flagging solving a specific hard foot-swap on a specific problem, which is legitimate application-level teaching. But it's tied to one gym's route and leans on visuals ('so this is here, and here') that don't survive in transcript form, and a chunk is just class-schedule chat.
