During the long jump, try to execute the jump as close to the line as possible so as not to waste valuable centimeters jumping over the run up track.
Running
When running, either for a Track event or as a build up for a Throwing or Jumping event, quick, small strokes back and forth across the touchscreen yield better results than wide swipes.
Throwing events
In throwing events, the build up is important, but hitting the right angle is even more so. Aim for a decent, rather than blistering buid-up to make it easier to get the throwing angle just right.
