 Isometrics are incredible at developing stability. Now here's the thing with isometrics. People tend to forget two things. One, nobody does them, which is stupid. Isometrics are phenomenal in a four week period of time. You could dramatically improve your stability through isometrics. It's of all the muscle contractions. This one produces strength gains the fastest. Here's the mistake that a lot of people make is they'll train an isometric in one position. Don't train the other positions. So in other words, a common isometric would be like a overhead hold. That's a good isometric hold. But I can also train it where I'm holding down here halfway or down here at the very bottom, you want to train different positions to build stability in different positions. And this is true for the core or for the shoulders or for the hips, all these dynamic joints.
