Calisthenics Outdoor Workout
Outdoor calisthenics workouts are a fantastic way to build strength, improve fitness, and enjoy the great outdoors 😁🦾
Calisthenics is a form of strength training that uses the resistance of your body and gravity to help strengthen your muscles and improve your coordination, endurance, and mobility. It’s a workout that relies on body weight with little or no equipment. In fact, almost all common bodyweight exercises are considered calisthenics exercises. Some examples include:
- airsquats - pushups - pullups - frogstand -handstand -musclup -backlever aso 😁
Whether you’re a beginner or an advanced athlete, calisthenics provides a holistic approach to fitness. 🏋️♂️💪
🌼🌼 Lellingen Daffodil Hike (12km) 🌼🌼
Hello Friends!
There is a forest in the north of Luxembourg, where at this time of the year millions of wild daffodils are blooming.
It's an incredible view, almost impossible to capture in a photo.
CFL is playing with us these days; there is either "Schienenersatzverkehr" between Luxembourg and Echternach or between Echternach and Wilwerwiltz.
The replacement bus takes twice as long as we would need by car, that's why it is a full "car pool exercise" this time.
We will need carpooling anyway if we want to leave the country once in a while, so let's get used to it!
We will start in Lellingen, and we will partially follow the "Via Botanica", which is dedicated to the daffodils that grow only in that area in such large numbers.
As usual, I've optimized the path a bit in terms of the distance to reach the picnic spot after about 7km.
The weather will not be that great, no rain, but way too cold for a long picnic, so we will leave before we get too cold.
We will then go back across the same yellow paradise and enjoy the view again, from a different perspective, then all the way down back to Lellingen.
**Meeting Point:**
We will meet at the start of the "Eisleck pad Lellingen".

**Car Pool:**
Please try to get in the carpool, everyone.
https://groupcarpool.com/t/hryx9p
Passengers may bring a pair of clean shoes for the return, although it's not expected to be extremely muddy this time.
But you never know, you may want to be allowed to be a passenger with the same driver again in the future :)
Drivers: You may need to plan 5-10 minutes for parking; it's a tiny village.
Passengers: When you add yourself to a car and don't remove yourself from the waiting list, then I will clean up the duplicate name from the waiting list at some point. Don't be scared if you get a message that you have been removed; you will still be in the car.
Unless the driver canceled their trip in total, better check, but don't add yourself again unless your driver is gone :)
**Public Transport:**
As a fall-back in case you can't get a seat in a car, you can take Bus L11, leaving at 8:44 from "Gare Rocade, Quai 6" (back side of the Gare, near "Rotondes").
You will arrive in Ettelbrück at 09:58, then take the train RE 3809 towards "Troisvierges".
You need to get off at Wilwerwiltz (10:34), then go left, cross the railroads, cross the river, and find the "Autopedestre", following it clockwise (going left) until Lellingen.
This will take you less than 20 minutes, and you will meet the rest of the group there.
**Disclaimer:**
The hike is at your own risk, and please make sure to wear proper shoes and bring some water for yourself!
Looking forward to hiking with you!
Jens.
Algorithmic Trading & Crypto
## (Lesson 2)
## What to expect
Project Equilibrium is an in-person introduction to disciplined, rule-based trading automation. This first event is designed to be clear, practical, and approachable no hype, no pressure, and no prior technical background required.
### Why we meet (two-session structure)
This meetup is structured as **two lessons**:
**Lesson 1 — The “Why” (mindset + framework)**
* What Project Equilibrium is (and what it is not)
* Why we focus on process, rules, and execution discipline
* What “24/7 execution” means in practice
* Q&A and open discussion
**Lesson 2 — The “How” (step-by-step setup)**
* A simple walkthrough of the basic tools you need
* Step-by-step guidance to install and prepare the required exchange apps/accounts
* A clear checklist to be ready for future sessions
(You won’t be left alone—everything is explained calmly and in order.)
### What to bring
To make the second lesson smooth, please bring:
* **A smartphone** (for authentication and exchange app setup)
* **A laptop** (for the setup steps and configuration)
If you only have one device, you can still join Lesson 1. The setup lesson is simply easier with both.
### Who this is for
* People curious about algorithmic execution and portfolio discipline
* Beginners who want a structured approach
* Experienced traders who want more consistency and less stress
### Agenda
* Welcome + introductions
* Lesson focus of the day (Why / How)
* Guided walkthrough (where applicable)
* Q&A + next steps
### How to find the group
* Arrive a few minutes early and look for the **Project Equilibrium** group.
* I will be there to welcome attendees if you’re unsure, simply ask the venue staff for the Meetup group name.
