Twites fly about in tight-packed, fast-moving flocks, with an explosive burst of twittering as they all go up.

It was as if all the troubles, setbacks, anger and frustration had been channelled into one explosive burst.

Slowly lower yourself into a press-up, then with an explosive burst, exhale and push yourself up, lifting your hands off the floor and clapping them together.

For example, some players may need to improve their power and the explosive burst over the first few yards to get away from their opponent.

Plus those explosive bursts of speed have another benefit.
