"30 Days of Push-Ups" は、筋トレ企画向けの、ざらついたスポーツ風のYouTubeサムネイルです。赤と白の重い文字が、赤いスピード線とともに腕立て伏せの途中のたくましい腕の横で右に積まれ、左半分は自分の写真を入れられるよう黒い無地のままです。自分の企画と期間に差し替えて作り直せます。

Create a finished 16:9 YouTube workout-video thumbnail, 1824 × 1024, designed for instant readability at phone size. Render only this exact text, with no additional words: "30 DAYS OF PUSH-UPS". Set it in three stacked lines on the RIGHT half: "30 DAYS" / "OF" / "PUSH-UPS". Make “30 DAYS” and “PUSH-UPS” the dominant lines; keep “OF” smaller but still bold and clear. Use custom ultra-heavy, slightly condensed block lettering with broad counters, blunt squared terminals, tight spacing and thick black keylines. Alternate bright white and saturated workout red across the words, with crisp flat fills, a narrow white edge highlight and a restrained hard shadow for separation. No gradients inside the letters. Keep the entire LEFT HALF a plain, uninterrupted matte-black photo-placement area: no lettering, props, streaks, texture or glow there. On the right, use a deep black background with a compact graphic of a muscular forearm and clenched hand braced on a dark gym floor, cropped without showing a face; red-and-white motion streaks angle toward the headline. Keep streaks behind the text and confined to the right half. Use hard directional lighting, sharp edges, high contrast and restrained red rim light. Keep all lettering inside generous safe margins and leave the bottom-right 20% clear of text and faces for the YouTube duration overlay. Avoid extra labels, badges, interface graphics, clutter, and small print.
