This exercise is side-to-side hopping on the spot, and is used to help someone return to impact activities such as running and sport.

It is best to perform this exercise when you have had a brief warm up of some other exercises, or before you are due to go running, depending on your level of fitness.

The aim is to hop from side-to-side where you are getting used to lateral movement impact. You should land softly and the exercise should not cause any pain, and you should be powering off each leg equally. Follow the guidance in your rehab programme for the suggested duration to complete this exercise.
