"A muscular man in his late 20s is in a gym, drenched in sweat

"A muscular man in his late 20s is in a gym, drenched in sweat, lifting heavy weights. His expression shows intense frustration, with furrowed brows and gritted teeth. His muscles are strained, and veins are visible on his arms and forehead. He’s wearing a sleeveless hoodie and gym shorts. The gym is dimly lit, with a few scattered weights and equipment in the background, adding to the gritty, intense atmosphere. The man’s posture is slightly hunched, and you can see the struggle in his body language, conveying his determination despite his frustration."
