Yes, you can train during a fast, but pushing hard is a mistake - scale intensity down and focus on light cardio, strength, mobility, and recovery. Done right, exercise helps you enter ketosis faster, preserve muscle, and maintain routine without adding unnecessary stress. 💬 This video isn’t sponsored.

I have three kids, a full life, and a constant drive to improve every aspect of my lifestyle. Over the years, I’ve come to believe that fasting is one of the most powerful tools in our health toolbox. That belief, combined with my love of data, led me to create this channel — a place to share real-world experiences and structured insights that can make fasting easier, smarter, and more effective for others.
