Beginner 5x5

I would suggest Rippetoe’s Starting Strength:

It’s 3x5, not 5x5, but its a basic beginner strength program. If you eat right and train hard, you could easily add 20+ lbs in a few months.

The Stronglifts Beginner 5x5 is also a good choice, very similar to Starting Strength but with slightly more volume (more growth potential, but you might stall faster).

Bill Star’s, Texas Method, and Stronglifts Intermediate 5x5 are intermediate programs, you will make progress, but not as fast as with SS or Stronglifts Beginner. I would suggest starting with a beginner program and moving on to an intermediate program when you can no longer make progress.
