i. bouldering 101

1. holds

  • jugs: the most basic, the easiest to grab
  • pockets: holes, you grab and hold onto with fingers
  • crimps: small surface, tip of your fingers, like one phalanx (not even) — 3 positions of crimping possible
  • slopers: sloppy slippery, round-ish, gotta use as much friction as possible, stay low and trust yourself
  • pinches: pinch with fingers
  • footholds

2. concepts

  • direction of pull
    • perpendicular to the best position of a hold
  • timing momentum
    • from your hips (best center of balance)
    • dead point, apex of trajectory max of a movement
    • hips close to wall as much as possible
  • 3 points of contact / triangle base
    • 2 hands - 1 foot
    • 1 hand - 2 feet
    • flag, smear to create more contact point and get stability if necessary
    • can also use lazy leg on opposite direction of movement to create more balance

3. techniques

from basic to more advanced,
to get an overview of the possibilities, the tool kit 🧰

techniquedescriptionwhy
matchplacing both hands or both feet on the same holdbody repositioning, + strength and stability
foot swapswapping feet on a footholdbody repositioning and balance
smearingbasically using your foot (or hands) on the wall directly, not on a defined holdprovide additional support and stability
drop knee/ backsteptwisting hip and knee inward, literally dropping the kneeallow higher reach
flaggingextend leg out to the sidecounterbalance
underclinggripping a hold from belowconverts pull into upward movement
heel hookhook your heel on a holdhelps pulling and stabilising, + support
toe hookhook top of your toe on a holdmaintain body tension, esp. on overhangs
sidepullpulling sideways on a vertical hold, opposite direction (can add a foot to help)body tension and balance
dynojumping dynamically to reach a distant holdwhen static reach isn’t possible
crimpingfull crimp (90°+thumb), half crimp (90°), open crimp (just dragging on the hold)on crimps, no choice
pogo/campusonly make use of your upper body (arms, hands) without the help of your feetno choice on overhanging climbs
gastonthat movement that looks like you’re trying to open the elevator door to save sb lmaooutward force/tension for stability
compressionit’s the inverse of the gaston, you sssqueeze opposing holdsinward force/tension for stability
mantlepush down on a hold with your hand/arm to get on top of it (like getting out of a pool)get on top of a hold, access higher holds
rock overuse foot and leg to push yourself on top of a holdget on top of a hold, access higher holds

4. grades

each climbing gym has their own grade systems,
can be really subjective,
but here’s some baselines

ii. tips

> tips for beginners

yeah yeah yeah… you hear that everywhere,
general rules tho (not to be followed to a t, obvi)

  • straight arms vs. bent arms, lock off
  • use tip of your foot i.e. toes vs. sole of the feet
  • use your legs more vs. exhausting upper body
  • hips close to the wall
  • move your feet first
  • … silent feet

> tips +

  • route reading and visualisation
  • use momentum more
  • know when/how to use static vs. dynamic
  • pay attention to bad/inaccurate body/foot/hand positioning

iii. personal journey

started (more seriously) indoor climbing / bouldering in september 2025,

i am excited about learning the different techniques— both in theory and in practice

i have been keeping track of progress and feelings in a detailed spreadsheet (as always),

as of october 2025, i can do V2-V3 problems,
my goal is to be more comfortable with V3, maybe start V4, by the end of 2025 (edit: wrist injury came back),

let’s see how consistent i can be,
my right wrist injury sometimes comes back,
and it takes couple weeks for it to be back to normal,
it’s a little bit sad,

but that’s just how my body is right now,

as you age,
you do accumulate a number of injuries,
being more careful and conscious of your abilities and limits is an important lesson.

something i have been trying to apply more consciously — it’s hard cause not always natural
