How to choose core exercises

Core exercises can challenge trunk stability, flexion, rotation and control in different ways. A practical selection can combine a bracing movement such as a plank with a controlled flexion, rotation or leg-raise variation depending on your plan. Use the exercise guides to compare difficulty and technique rather than treating every core movement as interchangeable.
