You're likely ready to progress if your current workouts feel comfortable and you're able to complete them with good form.
Signs you may be ready include:
You're completing all exercises with control.
You finish workouts feeling challenged but not overly fatigued.
Your workouts no longer feel as challenging as they once did.
Your fitness level or goals have changed.
If you're unsure, you can continue with your current program until it feels too easy, or update your plan to receive a new recommendation.
