Static Supination Hold
The static supination hold trains the isometric strength to hold an outward-rotated, hook-ready position under load — the strength that lets you keep a hook locked in rather than just get into one.
Muscles Worked
Supinator, biceps
Equipment
Cable machine
How to Do It
- 1Attach a handle to a cable or band
- 2Rotate into full supination
- 3Hold with maximum tension
Sets & Reps
3-4 sets · 10-20 seconds hold
Coaching Tips
- •Breathe steadily — don't hold your breath through the hold
- •Combine with a slight wrist curl for maximum cup
Common Mistakes
- ✕Holding in a neutral or under-rotated position instead of genuine full supination, which trains a different, less specific strength
- ✕Using a weight so heavy the hold breaks down before hitting real time under tension
