Hey my friends! I got the idea for this video because I’m getting a lot of people sending me messages about being worried they took a week off, didn’t train or eat like they do usually and fear losing their progress in the gym. If you’ve followed me for a while you’ll know I don’t really focus on the physique side of things and think of our bodies more as machines capable of doing so much. But I know that appearance can be a big goal for a lot of people so I thought I’d go into the science of what happens to our bodies during short periods of overfeeding. I hope you enjoy the video and I hope it can let you relax even more about taking breaks and enjoying life (:
