The Swift Cadence test is not the same as the normal 'fast feet' tapping style drills you may have seen before.
It is however a an extension of 'bounding' where it the aim is to have the whole body airborne between 'steps'
To achieve this you really need to focus on
- Having high knees
- Ensuring you actually have a phase between steps when NO FEET ARE ON THE MAT
Give this a try with this in mind and you will quickly see its a drill that requires some skill, and co-ordination.
