A medium shot from a side-angle perspective shows Valka from Genshin Impact performing a strenuous push-up training session. He is positioned horizontally with his palms pressed firmly against the ground, arms fully extended and elbows locked, while his torso remains straight and his chest is held aloft, not touching the floor. His arms are visibly shaking with effort, and although his legs are out of frame, his posture is rigid. He has his eyes tightly closed and his face is flushed deep red from the strain, his mouth open as he gasps for air while enduring the physical exertion. The background is a simple training area with a neutral floor and soft ambient lighting. The image is a high-quality anime illustration with clean linework, focused on the physical tension of the character's muscles and the intense expression of endurance.
