The barbell plates are shaped like giant birthday cakes, each with brightly colored candles flickering on top. The teen is wearing a bright, neon green tank top with a playful, oversized "Birthday Gains" logo emblazoned across the chest. Their workout shorts are a loud, polka-dotted blue and red, matching their vibrant, high-top sneakers.
