How would I make a route that shows where player moves beforehand?

I have a player gameObject that jumps up and down and moves in 2D. It has two rigidbody objects and joints that have meshes attached, so its movement is influenced by other objects.

It would help controlling the player if the game would show the route it bounces before it happens. The complexity of the gameObject prevents me to just make a sphere that copies the gameObject's attributes and leaves a trail, because the joints and such cause it to bounce and move irregularly.
