[0 YoE, Personal Trainer, Business Consultant, UK]

Im based in London, UK. Been looking for a job since I graduated in summer 2025. I have made it to first round interviews a few times but didnt go any further. Apart from that I dont get any replies from employers. I've been applying for early career roles in consulting/ business consulting. What are some ways I can improve my CV? any help would be appreciated. i currently work as a personal trainer in a commercial gym but its not working out.
