Idiom: "Beef it up"

Hi

A few days ago, or rather a few posts ago, Alan used the idiom “Beef it up” somewhere. As ill luck would have it, I haven’t so far been able to find the meaning of this expression anywhere. Could you please help me with its meaning and use? I could not find it on Google either!

Tom
