Core stability is the capacity of the muscles around the trunk and pelvis (abdominals, obliques, erector spinae, glutes, diaphragm) to maintain a stable, controlled spine during movement. It enables efficient force transfer between the upper and lower body — essential in nearly every athletic action, from a tennis serve to a deadlift. Core stability is better developed through anti-movement exercises (planks, anti-rotation holds, carries) than through high-rep flexion (sit-ups), and underpins both performance and lower-back injury prevention.
Key points
- Stable spine and force transfer
- Abdominals, obliques, back, glutes, diaphragm
- Best built via anti-movement exercises
- Underpins performance and back-injury prevention
