Don't train to survive fatigue, train to produce quality
A lot of programs rely on endless repetition, long warm-ups, and high-rep grinds. They build a high tolerance for suffering, but they also teach your body to move slowly, in compromised positions, just to get through the work.
That's the opposite of what you want on the mats. BJJ rewards explosive, repeatable efforts: a sharp hip escape, a fast sweep, a strong frame, then relaxing and doing it again. Heavy, sloppy fatigue ruins that.
Remember that acid is the enemy of both tension and relaxation, and it leaves you stuck in a stiff middle ground.
So train in this order:
General strength: the ability to create high tension on demand
Power: expressing that strength quickly
Endurance: keeping speed and coordination across rounds
Skill and timing: the deciding factor when two people are equally prepared
Keep your sets short and crisp, rest fully, and stop when speed drops. For grapplers, add grip endurance and isometric strength once the base is there.
