RPE stands for Rate of Perceived Exertion.

In simple terms, it means:
👉 “How hard does this exercise feel to you?”

Instead of using weights or numbers like reps, RPE is based on your own feeling during the workout.

In simple terms:
Think of it like a scale from 1 to 10:

• 1–2 → very easy (like a slow walk)
• 3–4 → light effort
• 5–6 → moderate (you feel it, but can keep going)
• 7–8 → hard (you’re working, breathing heavier)
• 9 → very hard (almost your limit)
• 10 → maximum effort (you can’t do another rep)

Example in the gym:
If you’re doing squats and feel like you could only do 1–2 more reps, that’s around RPE 8–9.

Why it’s useful:

• Helps you train safely
• Adjusts workouts based on how you feel that day
• Prevents overtraining or injury

Reps is short for repetitions.

In simple terms:
👉 A rep is one complete movement of an exercise.

In simple terms:
If you do a squat:

• Go down → come back up = 1 rep

Do that 10 times → 10 reps

Example:

• 10 squats = 10 reps
• 12 bicep curls = 12 reps

Simple way to remember:
👉 Rep = one full movement

A set is a group of repetitions (reps) done together without stopping.

Layman’s explanation:
👉 A set is like a “round” of an exercise.

Example:
If your workout says:
3 sets of 10 reps (squats)

That means:

• Do 10 squats → that’s 1 set
• Rest
• Do another 10 squats → 2nd set
• Rest
• Do another 10 squats → 3rd set
