Train close to failure, but don’t live at failure

[kherbo]

Muscle growth usually needs hard sets, but going to absolute failure on everything can burn you out and wreck recovery. A good standard is finishing most sets with one to three reps left in the tank, then saving true failure for safer movements like machines or isolation exercises. This keeps intensity high while protecting performance. Do you train to failure often, sometimes, or never?
Your form should serve the target muscle, not your ego
