Isometrics are one of the most undervalued tools in training.
I use them everywhere, from rehab and tissue remodeling, to motor learning, to performance work. That includes yielding isos (holding against load), overcoming isos (pushing into an immovable object) and pairing

them with dynamic movements.
In rehab, they’re often our first step back to movement. Studies have shown that even a few days of unloading can reduce tendon collagen synthesis and stiffness, so we can’t afford to stay immobile. Isometrics help restore neural drive, build

tension tolerance and remind the brain that it’s safe to produce force/start moving again.
Both The Art & Science of Sport Preparation and Speed Kills use isometrics and eccentrics throughout the programming and the eBook sections go deeper into why these contractions matter

You can grab them individually or bundle both for massive savings, almost a two-for-one deal.
