In Order to have balance there must be opposites
at every session I was making progress, without rushing, just staying patient until everything clicked. It was also much easier mentally than last year" Simon Lorenzi

claw grip training
20mm ish edge (comfortable, not max effort)
- Start hanging and pull with the fingertips, imagining “scratching the edge downwards.”
- Hold 5–10s.
- Rest 40–60s.
- 4–6 reps x 3–4 sets.
Hamish Fingertip Pulls” on a Plate or Doorframe
He sometimes practices this between reps while resting:
- Touch a surface with fingertips.
- Apply downward force JUST with DIP joint.
- The forearm flexors near the wrist and the FDP belly should activate strongly.
3–5 second micro-reps
8–12 reps
Very low load—this is activation, not strength work.
- Never overload the DIP with max-weight hangs.
This is a coordination + recruitment pattern, not a “max strength” protocol. - Don’t allow DIP hyperextension.
If the finger collapses backward → stop.
Many climbers (including Aidan and Hamish) combine both:
High-angle crimp
+
Active DIP claw
The strongest, most controlled crimp position for tiny holds.
This produces:
- maximal contact security
- maximal force through the deep flexor (FDP)
- better load distribution along the tendon
- fewer pulley tweaky positions vs. collapsed DIP
- more “precision bite” on micro edges
But high-angle ≠ claw unless the DIP is actively doing work.
🔍
Think of It Like This
High-angle crimp
= What the middle joint is doing
(PIP flexion)
Claw
= What the fingertip is doing
(DIP flexion)
You can have:
- High-angle + DIP collapsed → classic crimping, risky
- High-angle + DIP clawed → elite crimping, strongest
- Mid-angle + DIP clawed → Hamish semi-crimp claw
- Low-angle + DIP clawed → precision dragging / small holds
⚠️ WHY THE DISTINCTION MATTERS
If you train only
high angle
:
- Great for PIP strength
- But DIP may collapse → transfers stress to A2/A3
- Less precise hold engagement
If you train
claw DIP activation
:
- Builds control and force transmission from fingertip
- Protects pulleys by distributing load
- Works across multiple grip angles (not just high-angle)
Best results come from combining both, not confusing them.

Elite Examples
Hamish McArthur
Claw = recruitment + precision → DIP control
Aidan Roberts
High-angle = powerful crimping
Often adds DIP flexion, but doesn’t call it “claw grip”
Daniel Woods
High-angle half crimp often without full crimp
Less explicit focus on DIP activation
Still extremely strong because of raw PIP/A2 strength
