feedback please..

Hello! I am looking for something creative, unique, elegant and intense. I need a logo that is fitness related, either relating to the human muscle Fibers or to the fitness industry in general. I appreciate designs that are capable of integrating and using the two F's in creative ways. Also, the colors and materials in the overall design presentations make a big difference. Thank you all and keep the designs coming! have a great day!

Hi, submitted two logo design options. feedback please.
