**(Tickets and booking: https://www.lumiberlin.de/postpartum-decoded)** Your body after birth is not broken. It's doing something extraordinarily complex — and nobody explained it to you. Postpartum Decoded is a four-week workshop series that changes that. Every Friday in June, Paola Carrillo Bustamante — computational biologist, biomedical engineer, and mother — brings the real science of postpartum recovery into the room. Not as a list of symptoms to fix, but as a connected system to finally understand. Each session covers a different layer: **Week 1 (5 June) — Your Body as a System** Hormones, tissue repair, brain and nervous system — why recovery is a spiral, not a sprint. **Week 2 (12 June) — Your Brain and Nervous System** The neuroscience behind the fog, the identity shift, and intrusive thoughts — plus tools that actually help. **Week 3 (19 June) — Fuelling and Rebuilding Your Foundation** Why you feel depleted, what your body needs to rebuild, and why Kegels alone aren't the answer. **Week 4 (26 June) — Integration and What Comes Next** Bringing it all together and building your personalised roadmap forward. No platitudes. No bounce-back narratives. Just honest, science-backed information held with warmth and lived experience. **📍 LUMI Yoga & Pilates · Heidestraße 19, 10557 Berlin** **🕙 Fridays 10:00–12:00** **🎟 €25 per session · €85 for the full series** **Tickets and booking:** https://www.lumiberlin.de/postpartum-decoded

ENGLISH: **INNER GUIDANCE** **A Transformative Movement Workshop** **for all beautiful women / sisters** **Grow · Unfold · Integrate** The Inner GUIDANCE Workshop is an embodied journey into your inner knowing, wisdom, and clarity. Through free-form movement, dance, and gently guided impulses and intention-setting, you are invited to reconnect with your body as a source of guidance, truth, and trust. In a supportive and non-judgmental space, we move to alchemize inner obstacles, awaken joy in the body, express a freer, new version of ourselves, and return to our inner center. Gratitude becomes a shared practice, raising our frequency, cultivating unity within ourselves and with others, and opening us to authentic human connection—expressed through the language of our moving bodies and hearts. This workshop creates space to listen deeply to your inner knowing via the body in movement. You will be supported to just be you in the present moment, allowing and discovering change, strengthening self-trust. Besides dancing mostly for yourself there will be also some partner and group invitations in movement which you can join or not and some physical touch involved, of course all volunteerly. We will end with an relaxing integration time and little sound bath. No prior dance experience is required. There is no right or wrong way to move—only the willingness to connect with your inner compass: your body. Move towards your true self, guided from within. Come just as you are and wear comfortable clothing that allows free movement. **Energy exchange:** 20 Euro (normal), 15 Euro (reduced) The session may be held in German and/or English, depending on the needs of the participants. **Please register due limited spaces via email, PM, Meet Up message latest till Friday 05.06.2026:** EMAIL: soulbalance@mail.de I look forward to holding space for you. With love Mira (Certified Transformative Dance Facilitator & Integrative Dance Educator) *Note: This workshop is not therapeutic; your well-being remains your own responsibility. However, it may have therapeutic effects.* DEUTSCH: **INNER GUIDANCE** **Ein transformativer Bewegungs-Workshop** **für Frauen / Schwestern** **Grow - Unfold ·- Integrate** Der Inner GUIDANCE Workshop ist eine verkörperte Reise zu deinem inneren Wissen, deiner Klarheit und Intuition. Durch freie Bewegung, Tanz und sanft angeleitete Impulse verbindest du dich wieder mit deinem Körper als Quelle von Führung, Vertrauen und Wahrheit.

An opening of an art exhibition is a nice occasion to catch up and hang out. No agenda, just art, wine and chat. *** KIT Berlin ([@kitstudioartspace](https://www.instagram.com/kitstudioartspace)) invites you to an exhibition of paintings by Wiola Stankiewicz [@wiola_stankiewicz](https://www.instagram.com/wiola_stankiewicz/) “Now it Makes Sense, Isn’t It?” and a musical performance by Antonio Bastos [@antonio__bastos](https://www.instagram.com/antonio__bastos/) Now It Makes Sense, Isn’t It? continues the “Emotional Algorithm” project — a series of paintings built from intuitively selected screenshots, private photographs, and images found online. The images are combined like an emotional bajaderka (a Polish layered dessert traditionally made from mixed leftovers, fragments, and combined remains) — sometimes through color, contrast, or an unexplainable feeling that they simply belong together. The works explore screen aesthetics and digital ways of perceiving images. Meaning often appears only later. And sometimes not at all. Wiola Stankiewicz is a visual artist born in Elbląg, Poland, currently living and working in Coimbra, Portugal. Her practice focuses on painting, collage, and assemblage, using mixed media techniques and experimental material processes. Working with icons of popular culture, landscapes, found images, and photographs from her personal archive, Stankiewicz builds a coherent and autonomous visual language based on intuition and process. Her works function as images of an open character, in which meaning emerges from the relationships between image, material, and gesture. Antonio Bastos turns vulnerability into stage, community into sound and instinct into creation. From electronics to tradition, from improvised lyrics to shared movement, his music is born live and unfolds into a visual, emotional experience. With dozens of releases and festival shows, he was awarded People’s Choice at the IPMA (USA), blending performance with community creation — involving choirs, schools and local groups of all ages. Each concert is a seed sown in the territory, where the audience also becomes creator.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

An invitation to soften, slow down, and listen within. Through grounding movements, mindful breathing and guided reflection, this class creates space to reconnect with your body and nervous system. We begin with an intentional asana practice to awaken the body and build awareness from the inside out. As the practice unfolds, mindful movement and conscious breathing will support you in tuning into your emotional and physical state with greater clarity and presence in the now. The body holds stories, sensations, and emotions while the nervous system often guides how we experience them. This class offers a gentle space to regulate, reflect, release, and reconnect. Guided reflections are woven throughout the practice to support deeper self-awareness and integration. You’re welcome to journal, simply reflect internally, or engage in whatever way feels supportive to you. Please bring a journal and pen if you’d like. https://www.eversports.de/org/activity/0374c592-0743-4067-a6bf-7f1e47b11b1c

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###
