CoreKB
Carrying a single kettlebell at the side like a suitcase while walking forces the opposite-side obliques to resist lateral flexion for the entire duration of the carry — a simple but brutally effective unilateral core loading tool.
Demo: General S&C demo
Sets
3
Reps
30-40m or 30-40 sec per side
Rest
1 min
Contraindications
Low back pain when leaning — reduce load and focus on staying upright.Setup
Deadlift a kettlebell off the floor with one hand, standing tall with the bell at the side of the hip.
Execution
- 1Stand tall with shoulders level and square before starting to walk
- 2Walk with even, controlled steps, resisting any lean toward the loaded side
- 3Keep the ribcage stacked over the pelvis, not tilting sideways
- 4Breathe normally throughout the carry
- 5Switch sides after completing the distance or time
Key cues
- Stand tall, don't lean into the weight
- Ribs stacked over hips, no side bend
- Walk with purpose, even steps
- Grip the handle hard for full-body tension
Common faults
- Leaning the torso away from the loaded side to compensate
- Shoulder on the loaded side hiking up
- Short, shuffling steps instead of a normal walking gait
- Losing grip tension partway through the carry
Tweaks
- Increase distance or load progressively
- Add a pause and hold at intervals
- Progress to a heavier single kettlebell rather than two-hand carries
Progressions
