Mirror Muscle Mythbusters

Make a stylish vertical fitness mythbusting video in a modern home gym, focused on the misconception that heavier weights always create better results. Show a trainer comparing rushed heavy reps with slower, controlled repetitions using manageable dumbbells. Use a symmetrical 35mm mirror shot for the opening, then cut to a 70mm close-up of posture, a side profile showing range of motion, and a smooth slider move around the trainer. Use soft neutral studio lighting with a warm practical lamp, crisp on-screen checkmarks and X marks, subtle sound-design hits, and an approachable US creator tone. End with a clear visual comparison and a confident thumbs-up.
