The #1 gym tool you aren’t using yet? The RPE Scale.
When you’re just starting out, “lift heavy” is terrible advice. How heavy is heavy? That’s where RPE (Rate of Perceived Exertion) comes in. It’s a 1-10 scale that helps you measure your effort based on how you feel today, not just the numbers on the plate.
If you want to build muscle, avoid injury, and actually enjoy your workouts, you need to learn this tool ASAP.
