Not all isometrics are the same.
Different types. Different adaptations.
What you use and when you use it…matters.
We covered yielding, overcoming, and EQIs, but there are other useful variations too - Oscillatory isos, iso-dynamic, etc.
Understanding why you’re using

them gives you the ability to apply them where they matter most.
Inside the Project Speed Bundle, I break this all down.
Both Speed Kills and The Art & Science of Sport Preparation cover how to use isometrics and eccentrics in real training, what contraction types matter

Breathe easy, a new study “compared PIMA & HIMA strength & morphological training adaptations”
“con & ecc torque only inc following PIMA. Results suggest PIMA is more effective at improving strength, while HIMA is superior for inducing morphological adaptations.” (Lum et al.)
