Martyn Ford Instagram – Incredible drill for all athletes needing to work on reaction speed, balance and core function. Can be used as a warm up, part of a circuit or individually as a workout, but where ever you place this, I would definitely make sure to use it on a regular basis, great for working integral muscles within the ankles and knee joints. Remember, you are only as strong as your weakest part …. #training #fitness #muscle #reaction #speed #balance
