How to Bend Strings Correctly
A bend looks like a single finger moving, but the strength actually comes from the whole hand and forearm - the finger just holds the string while the wrist does the pulling. That's exactly why a bend done with 'just one finger' tires the hand out fast and often falls short of the target pitch.
Where the strength comes from
The bending finger should not work alone: place the neighboring fingers on the same string at the preceding frets so they can share the load. A controlled wrist rotation, much like turning a doorknob, is usually more stable than trying to bend with one finger joint alone. This is a reliable approach, though the exact mechanics vary with the string, direction, and the player's hand.
Which finger does the pulling
For a whole-step bend or bigger, the ring finger is the usual choice, backed up by the middle and index fingers behind it - the ring finger or pinky alone don't have enough strength for an accurate bend without over-straining the wrist. The pinky is usually left for smaller half-step bends, which need less force.
Which direction to pull
As a practical default, bend toward the center of the fretboard so the string does not slip over its edge: the thin strings are usually pushed upward toward the bass strings, while the thick strings are often pulled downward toward the treble strings. Other directions can work when they are comfortable and reach the target pitch, but 'toward the center' is a safer guide than 'toward the ceiling or floor.'
Thumb support
The thumb hooked over the top edge of the neck is the second anchor point, without which all the strength goes into just holding onto the guitar rather than into the bend itself. It's the same anchoring principle that matters for clean chords too (see the article on thumb position).
How to train it
Start on the lower frets (the string is physically stiffer there) with a half-step bend - only move to a whole step once the wrist motion feels natural. Pulling on the upper frets right away, trying to 'play it like the song', is a common reason a bend stays tense and imprecise.
