Gym Lingo 101: Key Terms and Tips to Help You Feel Confident While Lifting
 

When it comes to the gym, it can almost feel like another planet with an entirely different language! 

Between the acronyms, weird phrases, and overly complicated terms, it’s no wonder you feel like you need a translator sometimes!

In this episode, I’m breaking down common gym terms and lifting lingo in a way that actually makes sense. From reps and sets to volume and intensity, you’ll finally understand what the hell people mean when they say “progressive overload”, “time under tension”, “glute activation”, and more!

**Spoiler alert: you DON’T need to increase your weight every week (and you shouldn’t). Honestly…if you just slow down more often, you’ll build more muscle AND boost the powerful mind-muscle connection (one of my favorite things to focus on)!

The bottom line is, you don’t need to memorize every.single.term. to crush your workouts.

But…I DO want you to feel empowered to ask questions, tweak your training when needed, and lift with confidence. The gym shouldn’t be a place that intimidates you. This is YOUR fitness journey that you can own + totally kick ass with!!

  • What reps, sets & volume mean + why they matter for your workouts
