How to get better at long jump and triple jump in track?

Hi I am a teen and i think I'm good at long jump and triple jump but there are always some ways to get better. So I was just seeing if anybody knew some tricks to get better at it.|||When your walking around your house, take some big steps. I know you'll feel goofy but it helps. I don't exactly remember what it does but it makes it easier to jump :)
