This exercise involves squeezing a ball between the knees or thighs to activate the adductor muscles – the inner thigh muscles that pull the legs together. Because it’s isometric (no movement at the joint), it’s a gentle and effective way to build adductor strength, particularly in the early stages of rehabilitation.
This exercise has been recommended by the clinical team at London Bridge Sports Medicine as part of a structured rehabilitation plan. Always perform it as directed by your clinician.
