1. Think of the object used to play with (eg. tennis ball, football) as something that really bugs you, that you really want to hit
2. Tense yourself, and look for some form of anger. Direct it towards the object. you should feel an adrenalin burst
3. When the object comes to you, unleash that anger towards that object
4. More often than not you will hit it, and hit it well.
Seriously, this is advise for improving your reflexes in sport? I can’t believe that it took 4 people to collaborate on this garbage.
