In the second half of this article I will cover the 4 best isometric training methods for building size and strength. This will include a detailed discussion on the science of isometric training. In the first half of this article I will teach you the advantages and disadvantages of isometric training. Now let’s dive right into the heart of this comprehensive guide. I hope you have found this introduction to the world of isometric training helpful. They will be covered in more depth in parts 6 and 7 of this article. There are two main types of yielding isometrics: iso-dynamics and loaded stretches. They dramatically increase the amount of time under tension of your sets and stimulate the release of IGF-1 and other growth factors into the working muscle. Yielding isometrics are a fantastic tool for building muscular size.

This isometric rep was performed at the end of a rest-pause set to absolutely annihilate his chest. Here is a video of Dusty Hanshaw performing a yielding isometric contraction on the incline bench press: Bodybuilders often use yielding isometrics to make their muscles work harder and to stimulate muscular hypertrophy. Yielding isometrics are a little different: your muscles contract to prevent an external load from moving you. There are many different ways to incorporate overcoming isometrics including powerlifting style isometrics and a training method called “ isometronics.” I will cover these training methods in more depth in parts 4 and 5 of this article. They teach your body to recruit more motor units and help you obliterate your “sticking points” or weaknesses in a lift. Overcoming isometrics are amazing for increasing maximal strength. Powerlifters often incorporate overcoming isometric contractions by pushing or pulling a barbell as hard as they can against a set of safety pins.įor example here is Al Davis performing a bench press overcoming isometric contraction: Overcoming isometrics occur when your muscles are applying force against an immovable object. There are two main types of isometric contractions: overcoming isometrics and yielding isometrics. Isometric contractions occur when your muscles are contracting and producing force without actually moving. For example when you are lowering yourself down from the top position of a back squat to the bottom position you are performing an eccentric muscular contraction. For example when you bench press a barbell from your chest to the lockout position you are performing a concentric muscular contraction.Įccentric contractions are the opposite: they occur when you are lowering a weight down under control. There are three different types of muscular contractions:Ĭoncentric contractions occur any time you are lifting a weight up with your muscles.
