If you list the biggest and fastest-growing technologies over the past decade, artificial intelligence (AI) will inarguably top the charts. The global AI market was valued at 39.9 billion in 2019 and is projected to grow at a CAGR of 42.2% during 2020-2027, according to Grand View Research. AI has found applications in every industry, and the fitness sector is no different. Smart fitness wearables, AI-powered fitness apps, and AI and Machine Learning (ML) for gym management are common use cases of AI in fitness. But not many people thought that there would come a time when AI will be on the verge of replacing personal trainers and fitness coaches.
