This is the gripping moment that was as captured in a local gym where a remarkably thin man struggled with muscle tremors during his workout.

On October 24, 2024, in Baoding, Hebei, the video showcased Mr. Geng, a 90-pound man standing at six feet tall, engaging in strenuous muscle-building exercises.

His arms shook uncontrollably while he lifted weights, a testament to his fragile physique and determination.

Mr. Geng, who had previously gained attention for his "butterfly wings"—exceptionally thin arms—mentioned that he had been consistently working out for a year and had successfully gained 22 pounds.

The video ended without a specific resolution, but Mr. Geng remained committed to his fitness goals, continuing to gain weight and strength through regular workouts.
