Well, the champ Ronnie said it! If you want to be a bodybuilder, you HAVE TO lift those heavy-ass weights!
More precisely, you have to lift PROGRESSIVELY HEAVIER weights. This is not just a fancy motivating quote, this is what tells you about the most important bodybuilding principle called “progressive overload”.
That simple principle implies a gradual increase in the weight, sets, and reps of your exercises.
Only through progressive overload, you can stimulate the body to grow bigger!
Now go lift.
