rebounding skills

hello
I'm new to a SF, PF positions
I'm usually a G
what are the drills that i can make a habit of boxing out and rebounding
I can box out but not quick enough to react to get a rebound
my teammates said i play soft as a post
also i make shots too hard on the board
thanks!

Read this article about rebounding. The key is to anticipate (know where the shot is going -- often the weakside), carving out great position by using your body, and then going after it (effort and desire).
