The 8 Week Program was perfect for me to build jiujitsu strength and supplement my training for No-Gi Pans where I brought home gold! I felt like the movements translated well to those in the sport and kept the hard training for sparring. Will be recommending to my teammates and very excited to start the Farm Boy Strong Program.

This is the dominate the Match Jiu Jitsu strength conditioning program.
It is 8 weeks out of camp training that involves 3 strength sessions and 3 conditioning sessions, with the last two sessions being optional, and then a 6 week competition cycle to peak you for a competition.
I've heard countless times number of people that have come to me and asked me what they should do for conditioning...
Should I do low intensity or high intensity?
How to structure strength training and when they should do it in the week?
Or that they don't do any strength training cause it makes them too sore.
How do they even find the time to do it?
This is what this program addresses, and allows you to just take the program and implement it into your jiu-jitsu training week to maximize the benefit of the sport to get bigger, stronger, more conditioned,...
And not gas out through scientific and evidence based principles that I've applied at the professional sporting level.
Not only do you get this program, but within the app, you get access to every single program.
So there is a full year of training programs called the grappling 365, which you can do after this.
And there's also a private community where you can message me if you have any issues like having to substitute exercises.
Maybe you've got a competition coming up, or you're not sure where to place your strength or conditioning days?
You can message me in there. I'll answer you and help out.
And you can join at no risk to you.
If you just go below this video, there will be a 7 day free trial.
You can try any of the programs. You can try an entire week of training.
If you don't like it, you just cancel.
It's really that simple. I look forward to seeing you inside and helping you out with your strength and conditioning for jiu jitsu.

Depth of knowledge broken down for the layman
James de Lacey is, without question, one of the very best strength & conditioning coaches I've come across. His depth of knowledge in strength & conditioning, especially as it applies to combat sports, is exceptional, second-to-none. He conveys his comprehensive knowledge with carefully thought out programs that are sensible and efficient in a clear and concise writing style. He's able to break down complex topics and make them easily understandable for the layman. This is one sign that someone knows what they're talking about and James definitely knows what he is talking about in spades.

I wasn't tired at all after 5 rounds
I felt great at open mat! Wasn’t tired at all after 5 rounds, made everyone else gas out and tapped them. I'm gonna be 42 next year and still keep up with the 20 year olds.

The course showed me how to put all the practices together
I put the Unleash Your Inner Beast Course into practice before my fight. I have been doing meditation and breathwork for a few years, also tried some visualization, but never in a consistent or ordered way. The course helped me with the frame and how to put all of the practices together, and how to actually apply them.

About James de Lacey
I’m James de Lacey and I love to help fighters like yourself become absolute machines. I have a Master’s in Sport & Exercise Science and spent my career working in professional and international level sport as a strength & conditioning coach before dedicating myself to combat athletes.
While I’m a practicing martial artist, my passion lies in helping fighters cut through the absolute dogshit training advice presented on social media from various weekend-certified “trainers.”
You’ll see I love the science behind training. I’ve published research in the exercise science space and continue to avidly read, interpret, apply, and collaborate with various coaches and researchers on the latest findings.
This program is based on the years of experience working with athletes and training myself. I hope you enjoy this unique take on BJJ S&C!

I feel great doing Dominate The Mats
I feel great doing Dominate The Mats. I was a monster at blue belt, but because of covid shutdowns and getting sick, I lost my gas tank & strength I had before. Now thanks to what you’ve offered, I’m getting it all back!

Professionalism and vast experience to novice all the way to elite level
James is one of the most knowledgeable and passionate coaches I’ve ever had the opportunity of working with. His understanding and application of the many facets of Strength and Conditioning is beyond comparable. Not only does he bring professionalism and vast experience to novice all the way to elite level, he is also patient and clinical when it comes to coaching. If you get the chance to work with him it will be one of the best opportunities you ever experience.

James' course was by far the best
I've done 5-6 courses about conditioning. James' course was by far the best. It cleared my mind about conditioning and now I see the mistakes many are making that I won't make again!

Since I started the program, I've noticed a significant improvement in my conditioning during my MMA training sessions. This program has been a game-changer. It has translated directly to better performance in training. I feel more capable and confident going into my future fights, and I credit much of that to the Sweet Science of Fighting Underground. I highly recommend this program to any combat sports enthusiast looking to take their training to the next level. It's a smart, science-backed approach to strength and conditioning that delivers real results.

The community is hosted within the Training App itself so everything is in one place. You can message in the community and even DM me if you have any issues.
If you want to use the community to ask questions about your coaches program, then this isn't for you. If you have questions or issues with your training, you need to talk with your S&C coach. We don't know the what, when, why, and how of your programming and it's be disingenuous of us to try figure that out. However, if you have an S&C coach and you just want to learn more about physical preparation for combat sports, then we'd be happy to have you!
You will benefit greatly having expert coaches and researchers guiding your training protocols. While your number one focus is the combat sport you've chosen, getting your week structure and physical preparation right from the start will help propel your progress instead of leaving you lagging behind.
Kudos to already having a strong physical base! This community is about mastering the art of physical preparation for combat sports. If you feel you've got that down and don't need to learn anything more or new, then this community isn't for you. If you feel you need a push in the right direction with your training to best transfer to the ring, cage, or mats, then you're in the right place.
It definitely is. You'll have access to a wide range of professional coaches and researchers on the cutting edge of physical preparation. Further, many have years of experience training athletes like yourself. Get your training problems solved by asking a question within the community or on the live Q&A. If you need something tailored to you, then we can see if any coach has availability to take online clients.
We understand the importance of mental skills in the fight game. As part of your SSOF Underground community membership, you get free access to our Unleash Your Inner Beast Mental Skills Course by Mental Skills Coach and 6x Karate World Champ Mona de Lacey. Further, she will be in the community to answer any mental training questions you may have.
Unfortunately, we cannot give medical/rehab advice. For one, it's near impossible to diagnose what's wrong over the internet. And two, you need to see a specialist in person to ensure you're getting the right treatment. Further, there are legal implications to giving this kind of advice.
Simply go into your profile within the training app, click subscriptions, cancel subscription. Couldn't be easier!
We are a group of coaches and researchers dedicated to educating and teaching what are have learned and applied. So yes!
You will not be refunded the rest of the membership. However, you will remain in the community until your renewal date where your membership will be cancelled.

My Personal Note To You
There are many coaches forcing their way onto your phone screen that don't deserve the attention. This is logical, results driven programming I've developed from years coaching in the real world with professional and international teams and athletes. I'm excited for you to experience the level of knowledge and cutting edge methods you can apply to your training.
