Gianni Grippo has become one of the most prominent Jiu-Jitsu athletes to publicly embrace ecological training.

The ecological approach – focused on learning through live resistance rather than traditional drilling – has sparked intense debate in the grappling community.
At its core, it emphasizes learning by doing, often through games, rather than memorizing sequences through repetition.

Grippo’s transition is particularly notable, given his long and successful competitive history using conventional methods.
Speaking to FloGrappling, Grippo explained what drew him to ecological training:

I definitely took a complete 180 but also it just came with like getting older, having more responsibilities, not wanting to spend eight hours a day on the mat.

I do feel like, first of all, just from a time-perspective ecological approach is better, because you’re more efficient with your time.
Also like, after a while, you just need to find different ways to learn.

Unlike some advocates who are critical of traditional methods, Grippo took a more measured stance:

I’m not gonna be that eco guy that’s gonna bash drilling, because I did it for so long and I think I was able to make it work for myself.

But being introduced to eco and CLA, I do find myself learning in different ways and being just as productive.
Or actually let me just say that right, being more productive with my time.

Grippo also provided a concrete example of how this approach transformed part of his game that had previously felt underdeveloped:

My standup has always been kinda mid throughout my career and I remember I was going to my buddy Kyvann’s gym at Bodega and we were working on like a game just starting from an underhook, starting from an underhook on the feet.

The goal was to only find ways to get their hands or hips to the mat any way that you can, and I had zero idea how to do that.

But just working from that position for 10 minutes against live resistance, in that 10 minutes I was able to find three, four, five ways to get their hands or hips to the mat.

The immediate impact was clear to him, but the long-term benefits are what truly solidified his belief in the method:

That became a strength of mine because I would keep working it against resisting opponents.
Whereas I feel like drilling when you’re doing it against someone that’s not really fighting back or there’s no resistance, I don’t know if you really get the proper reactions.
