Worth It? ZBiotics

Main Course: Getting this thing right is more important than ANYTHING else for building muscle consistently and sustainably. Progressive overload — it’s the backbone of any successful training program, but most people either overcomplicate it or misunderstand it completely. In this episode, we break down what progressive overload actually means (“doing more over time”), why it’s not just for powerlifters, and how to apply it without burning out or getting hurt.

We cover everything from how to track your progress, when to increase load or volume, and the subtle ways you can improve without adding weight to the bar. Whether your goal is strength, size, or just moving better, you’ll walk away knowing how to make real, measurable progress that lasts.

Q&A: Why am I more consistent and have more of an urge to do cold plunges when the weather gets cold instead of mid summer when it’s hot out? I’ve been in Lake Michigan 4 times this week and love it, but didn’t fill up my cold plunge once the last 4 months of summer.
