Depict a muscular male figure in his mid-30s, with a strong jawline, prominent facial features, and a determined expression, sweating profusely as he intensely works out at a modern gym, surrounded by sleek metal equipment and mirrored walls, with a warm color scheme and soft, dramatic lighting that accentuates the contours of his body, wearing a fitted grey tank top, black athletic shorts, and scuffed up white sneakers, his dark brown hair messy and disheveled, his skin glistening with perspiration as he grips a heavy dumbbell in each hand, his biceps and triceps flexed to their limits, with a few strands of hair clinging to his forehead, and a look of fierce concentration etched on his face as he pushes himself to the limit.
