How to Enhance Your 1RM (One-Repetition Maximum)

Boosting your 1RM entails enhancing your maximal strength. There are numerous approaches to achieving this, with the three primary ones being the improvement of:

  • Muscle Mass: Increasing muscle size equates to increased force production. To efficiently build muscle, explore our muscle group training guides available on this page. Technique: Enhancing your technique enables you to better utilize your existing muscle.
  • Technique: Enhancing your technique enables you to better utilize your existing muscle mass. Refer to our exercise technique guides, particularly those for the squat, bench press, and deadlift, for valuable insights.
  • Neuromuscular Efficiency: The final component of the equation revolves around how effectively your muscles activate, contract, and coordinate. Our strength training programs are highly effective for enhancing neuromuscular efficiency while concurrently promoting muscle growth.
