Create a modern and bold logo for a gym called 'OPTIMUS'. The logo should feature a strong and clean typography, using bold, sharp lines to convey strength and professionalism. Incorporate elements that evoke fitness, such as a dumbbell, a barbell, or the silhouette of a silouette of women on muscular figure. Include a sense of movement or progress, such as an upward arrow or dynamic lines. The color palette should focus on powerful colors like black, red, or gray, possibly incorporating accents of gold or white for contrast. Keep the overall style minimalist, with a clean design that can be used across different mediums like clothing, social media, and signage.
