1. Activation and warmups
Most of my ab work has me retraining my hips to work with my abs. This entails me squeezing or pulling my hips against an unmovable force while I brace. The unintended benefit is that everything I want to train gets WARM real fucking quick without burning out.
Returning to knee mobility is so damn easy when the muscles that were locking up just underwent maximum effort with minimum range of motion.
2. Future warmups
Tbh there isnt much to add besides a note for future me. Warmups have always been lifting lighter weights with the movement i intend on using. Test the format below:
Warmup and lifting
Isometrics.
Dynamic (power). Low volume.
Strength. Mobility between sets.
