My journey with online personal trainers opened my eyes to both the potential and limitations of digital fitness coaching. I experienced the value of personalized guidance but also felt the frustration of delayed responses and limited availability. The cost of consistent, high-quality personal training was a significant barrier to long-term commitment. I saw how trainers struggled to balance quality service with scaling their client base. As a technology enthusiast, I recognized the untapped potential of LLMs in fitness coaching. These observations sparked an idea: What if we could harness LLMs to provide instant, personalized fitness guidance at a fraction of the cost? I envisioned a platform that could: • Offer 24/7 support and instant feedback to fitness enthusiasts • Make personalized training accessible to those just starting their fitness journey • Empower personal trainers to scale their businesses without sacrificing quality • Reduce the intimidation factor for newcomers with tailored, step-by-step guidance This vision led to Zenfit – an AI-powered fitness platform bridging the gap between generic workout apps and expensive personal training. It's still a proof of concept, but I'm excited about its potential to democratize personalized fitness coaching and empower enthusiasts and trainers with AI
