Quick Answer: String slap almost always comes from bow arm elbow rotation or a grip that’s too far into the palm — rotating your elbow slightly outward and adjusting your bow hand grip usually fixes it faster than any arm guard alone.

An arm guard stops the sting, but it doesn’t stop the string from hitting your arm in the first place — and that repeated contact usually means a specific, fixable form issue is happening on every single shot.

What’s actually causing the string to hit your arm?

In the overwhelming majority of cases, it’s your bow arm elbow rotated too far into the string’s path, or a grip that’s too deep in the palm, which pushes your wrist and forearm inward. Bow design and draw weight can be minor contributors, but form is the primary cause almost every time.

How do you fix elbow rotation?

At full draw, your bow arm elbow should rotate slightly outward (away from the string), not stay flat or rotate inward. A simple check: have someone watch from behind at full draw — if your elbow crease points up or toward the string, rotate the elbow out until the crease points more toward the ground.

How does grip affect string slap?

A grip too deep in the palm (‘death grip’) pushes your wrist into the string’s path. The fix is a lighter, higher grip — let the bow rest more in the meaty pad below your thumb, with fingers relaxed, not wrapped tightly around the riser. This alone resolves string slap for a large share of archers who try it.

5 Mistakes That Keep Causing String Slap

1. Only wearing a thicker arm guard instead of fixing form. This just changes what hurts, not why it’s happening.

2. Gripping the bow too tightly. Tension travels straight into wrist position — a relaxed grip fixes more than people expect.

3. Not checking elbow rotation at full draw. This is the single most common root cause and the most commonly skipped check.

4. Clothing with loose or bulky sleeves. Fabric bulk near the bow arm can catch the string even with otherwise correct form.

5. Ignoring stance rotation. An overly open or closed stance can indirectly force elbow position — check your foot alignment relative to the target too.

FAQ: Archery String Slap Questions, Answered

Is string slap dangerous or just annoying?

Mostly annoying and a sign of a form issue, but repeated hard slap can cause real bruising and, rarely, more serious injury with high draw weights — worth fixing rather than just enduring.

Will a different bow fix string slap?

A properly fit bow (correct draw length) can help, but for most archers, elbow rotation and grip are the bigger factors regardless of bow model.

Do I still need an arm guard once my form is fixed?

Many archers keep wearing one as a habit or for loose sleeves, but a good guard should become a backup, not the primary fix, once the underlying form issue is resolved.

TL;DR:

• String slap is almost always a form issue, not a gear issue
• Rotate your bow arm elbow slightly outward at full draw
• Use a relaxed, high grip instead of gripping deep in the palm
• An arm guard treats the symptom — form fixes the cause

Check elbow rotation and grip before buying a thicker guard — most string slap disappears once those two are fixed.
