If you;re using clips, it's a hell of a lot easier than using flats. Get enough speed to bunnyhop the object. Compress your front end and then as you approach the object, start to uncompress at the same time lean back and pull the front up. Pull your knees up which in turn brings up your feet/pedals. Try to level out by pulling your rear up and then try to land evenly on both wheels. This link will help with bunnyhops using flats.
