Design a logo that features an icon of a flexed bicep, stylized to form an archway that resembles a cave entrance. The logo should convey a sense of power, strength, and resilience, symbolizing the brand's foundation in fitness and personal empowerment. The bicep should be detailed enough to be recognizable but simplified to ensure clarity and impact when scaled down. The archway formed by the arm should invite a sense of exploration and journey, reflecting the brand's commitment to guiding individuals through their fitness journey. Use strong, clean lines to depict the flexed arm, ensuring that the logo is effective in both color and monochrome. This design should resonate with the audience, portraying the brand as a beacon of strength, stability, and support in their fitness endeavors. --style raw
