CoreKB
A ballistic single-arm kettlebell movement from the hike position to an overhead lockout in one continuous motion, requiring the core to control rotational and anti-lateral flexion forces as the bell accelerates and locks out overhead.

Contraindications
Shoulder instability overhead — build the swing and clean first. Wrist bruising if the bell path is incorrect.Setup
Hike a kettlebell back between the legs like a swing, one hand gripping the handle.
Execution
- 1Drive the hips forward explosively to project the kettlebell upward
- 2Guide the bell around the wrist as it rises, avoiding banging the forearm
- 3Punch through to a full overhead lockout as the bell arrives
- 4Keep the core braced to resist rotation and lateral lean under the overhead load
- 5Guide the bell back down into the next hike, absorbing with the hips
Key cues
- Hips drive the power, not the arm
- Punch through at the top, don't just catch
- Keep the core braced through the entire arc
- Absorb the descent with a hinge, not the low back
Common faults
- Muscling the bell up with the arm instead of hip drive
- Banging the forearm on the way up (incorrect bell path)
- Excessive lateral lean to catch the overhead lockout
- Losing core brace at the top, causing lumbar extension
Tweaks
- Master the kettlebell swing and clean before attempting the half-snatch
- Reduce load significantly while learning the bell path
- Progress to full snatches once half-snatch technique is solid
Regressions
Muscles
Primary: Obliques, Glutes, Shoulders
Secondary: Hamstrings, Erector Spinae, Grip/Forearms
Notes
ROTATION (flagged), heavily core-dependent ballistic movement requiring anti-lateral flexion control at lockout.
