Build Dense & Athletic Muscle

"I started doing the Warrior 20XX as my conditioning routine, these are really fun and tough workouts depending on the intensity you do them with"- Roni Tuomi

You will push your body to the limits which will boost your hormones and as a result promote muscle gain. You will work your muscles very thoroughly and hard to make them grow bigger and stronger.


If there is one quality that separates athletes and fighters from the rest, it's called...


The ability to endure and sustain your performance at a high level without losing performance.

Normally, this is considered to be only a physical attribute. The psychological aspect, which is less talked about, is equally if not more important.

It's not enough to have strength endurance and cardio, you also need to be psychologically strong enough to push to your limits. Not only in competition but also in training.

Without this quality, you will not be able to develop anything to a high level. Moreover, without mental fortitude you cannot even achieve anything worthwhile in life.

For the longest time, we focused mainly on the other physical qualities such as strength and mobility.

We never could have understood how important strength endurance actually is and how brittle our minds were when tested in the fire.

Warrior 20XX will produce incredible physiological effects, the strongest you've probably witnessed so far, but it will also develop your mind.

Understand this: "PHYSICALITY = MENTALITY."

The mental development will evidently show in your physique and vice versa.

Warrior 20XX will literally forge you in the fire.

Don't learn to deal with the fire. Become the fire.

Are you ready to show the world how strong you've become?

Is this for beginners? Female?

Yes! We have 4 difficulty levels available in Warrior 20XX:

  • Beginner
  • Intermediate
  • Advanced
  • Elite

In addition to this, every workout has 2 additional “championship rounds” if you need to increase the difficulty of the workout.

Both males and females are welcome. So are people of all ages and body types.

I don't have dumbbells or kettlebells! The weight?

Not an issue. Bodyweight workouts alone will give you great results you are looking for but we highly recommend getting an adjustable set of dumbbells – they are very inexpensive and easy to find. It's really a small purchase.

For most kettlebell workouts you can easily replace the kettlebells with dumbbells.

The weights we use for Warrior 20XX are typically:

- One or two heavier weights from 8 to 12 kg (16-24 lbs)
- Two light weights from 2 to 5 kg (4 to 10 lbs)

It’s also possible to replace the dumbbells with two water bottles, or use just weight plates for the light weights.

The weight varies depending on the person's level, gender and size.

How does the course work?

After purchasing, you’ll get email with your personal login details to the course. The course platform works on desktops, laptops, tablets and smartphones. The platform is extremely easy to use.

The price is shown in $ USD but you will automatically pay with your own currency.

Are there bonus routines?

Warrior 20XX Method comes with lots of bonus routines featuring clubs, maces, resistance bands, barbells and even a sandbag. All workouts are designed to make you as fit and as functional as possible!

How are the workouts in Warrior 20XX?

Warrior 20XX consists of follow-along workout videos. In addition there are tutorial videos for each exercise used in the workouts. There are nearly 90 videos in Warrior 20XX alone and additional 12 video lessons in the online course.

The workouts typically last from 25 to 35 minutes including the warm up and cool down routine. In the workouts you have the option to go for 3 rounds or 5 rounds per workout.

After purchasing, you will get your login credentials to the platform which is high quality and easy to use. You will find the workouts there which are also downloadable for offline use.

What kind of results can I expect?

There is no doubt you will build strength, lose body fat and build muscle mass as long as you do the workouts consistently for a long time and your diet is good.

Warrior 20XX is the best style of training for getting a lean ripped physique.

What is the schedule of Warrior 20XX?

We give you many different schedules to follow: 3 times per week, 4 times per week, 5 times per week and a workout every other day.

Warrior 20XX can be easily integrated to your schedule and lifestyle.

Thanks to the number and versatility of the workouts, the workouts will produce results forever. Bodyweight workouts alone can last for months and produce fantastic results. In addition to this, we have the 30 Days of Discipline Bootcamp which you can choose to participate in or not.

How does the personalized plan work?

You will get everything as with the regular plan (lifetime access to the program) but also 3 months of online coaching with Eero Westerberg.

The online coaching includes an initial video call with Eero (usually 60-120 minutes long) and based on that there will be a personalized plan with everything you need. After that, there will be a follow up call and email support & form check analysis for 3 months.

This is the best plan if you are serious about your goals and need everything customized to your needs and goals. This is also the best plan if you need a coach to keep you accountable.

After purchasing, you will get an email from Eero within 24-48 hours with more details in regards to how to proceed.
