Ever joined a gym... and then had no idea what to do?

You walk in.
You see many different kinds of machines.
Everyone looks like they know exactly what they're doing.

So you end up...
❌ Walking on the treadmill
❌ Trying random machines
❌ Leaving after 20 minutes

If this sounds familiar, you're not alone.

That's exactly why I created my 5-Session Beginner Training Program.

In just 5 sessions you'll learn:

✅ How to use gym machines correctly
✅ Proper dumbbell & barbell technique
✅ How to build your own workout plan
✅ Basic nutrition principles
✅ The confidence to train by yourself

By the end, you won't need to copy what everyone else is doing.

You'll know exactly what you're doing.

📍SportCity Amsterdam Arena
💶 €250 (5 × 60-minute sessions)

Perfect for complete beginners.

**8-week Program Result**

Let me share one of my client’s stories.
She was my very first client in my newly developed 8-week nutrition + group training program — and she achieved an amazing transformation.

(Original comment is in the image — here’s the English version 👇)

〜Client Transformation Story〜

Before starting, I often felt discouraged when I saw photos of myself — it was clear I had gained “middle-age weight.” I knew I needed to change, but I kept putting it off.

I chose this coaching program because it combines both nutrition and training. I knew that on my own, I would likely make excuses, so I wanted structured guidance for a set period. I was also reassured working with a Japanese coach who understands body differences and mindset.

What stood out most was how effective the basics were. By simply visualizing calories, nutrition, and strength training, I was able to see real results. The weekly Sunday check-ins, along with group training, helped me build a consistent routine.

Physically, my body feels much lighter. Mentally, I’ve started to enjoy creating meals that are both healthy and satisfying. Surprisingly, my food expenses even decreased. I can feel that I’m building sustainable habits through both diet and exercise.

Compared to before, I feel more confident — like I can truly change if I commit. People around me have also noticed that I look healthier, both physically and mentally.

I would recommend this program to anyone who believes weight gain is simply due to age. Often, it’s about daily habits we don’t notice. Once you become aware of them, change is absolutely possible.

What I appreciated most was that the diet was not restrictive. I was encouraged to eat more carbohydrates than expected, could still enjoy eating out, and felt almost no stress. Tracking meals was challenging at first, but it helped me clearly understand my nutrition — and that made all the difference.

I would like to share one of my client's voices.

We made a huge progress on not only just numbers like weight or body fat but also body recompositioning, making a healthier habit, how strong he feels.

"My biggest struggle before starting was staying consistent, as I have a long on/off history with exercise.

I decided to get your help because I felt that there were gaps in my knowledge, both about diet, as well as exercise. Plus I needed someone to keep me accountable.

I've really enjoyed learning new things, being encouraged while working out & adding some much-needed structure to my life.

I've managed to steadily get stronger, as well as lighter. This is the best I've felt in at least 10 years now, which in turn has really helped me understand the importance of discipline.

I feel like I've been able to build the foundations for lasting lifestyle change through Daichi's guidance. Prior to this, I really felt myself getting old & I didn't think I had it in me anymore.

I'd recommend this program to anyone who's ready to turn over a new leaf & make real improvements in their lifestyle."
