Question

What is the difference between core endurance and core strength

Answer 1

A better question is what is the difference between core stability and core strength?

To answer:

CORE STABILITY:

Core stability is essentially the ability to maintain your balance without falling over; the ability to keep your posture and position stable. Core stability training (where the abdominal muscles are concerned), demands that you resist moving your lumbar spine by engaging all of your abdominal musculature. Your ability to use your muscles to keep you in a stable position is very important, and the development of core stability is entirely concerned with ensuring you deviate from your chosen position as little as possible.

CORE STRENGTH, AKA; CORE ENDURANCE:

Core strength should really be called core endurance, as it is entirely concerned with your ability to hold a position while resisting fatigue. Ensuring you are capable of holding your chosen position over a period of time, and that you can repeatedly hold a position or posture, all the while resisting fatigue, is what core strength is all about. Unlike training for core stability, when you train for core strength (again, with your abdominal muscles), you can allow motion through your lumbar spine as you endeavour to work your abdominal musculature. This is often isolated, working different muscles at different times, rather than engaging all of your abdominal musculature in order to remain still and resist fatigue.
