Part 2: The Opportunity Cost Argument

This is ultimately a conversation about what you do with limited training time.

A competitive practitioner training seriously is already accumulating a substantial aerobic load with technique classes, drilling, positional rounds, open mat, and competition prep. The aerobic system is not being neglected.

What is often neglected is the development of raw speed and power, precisely because those qualities feel less specific to grappling. There's no obvious carryover when you're thinking about the sport tactically. But the carryover is real; it's just operating at the level of energy systems and mechanical efficiency rather than skill.

So the question for grappling isn't whether conditioning matters. It's whether the training time spent on manufactured aerobic work would be better invested in speed and strength development; qualities the mat is not going to build for you. If you spend your S&C time doing sprint repeats thinking you're building a conditioning base, you've spent your one window for power development on something the sport is already doing.

What This Looks Like in Practice

None of this argues against hard training. It argues for clarity about what each training stimulus is actually doing.

Maximal effort work (short, explosive, fully recovered) develops the speed reserve that makes your mat time feel easier over time. Strength work builds the power output that underlies every explosive action in grappling.

Aerobic development, to the extent it needs supplementing, should be deliberate and understood as distinct from speed work, not conflated with it.

The grappler who understands this stops chasing the burn as a signal that speed work is "doing something."

The burn means you've exceeded full recovery and started taxing a different system. That might be the goal on certain days. But if speed is the goal, the burn is a sign you've drifted off target.

Translated to the mat: don't mistake going hard for going fast. Use it to get faster. And trust that getting faster is its own form of getting in shape.
