Early in my career working with elite Sprint Kayakers in the London 2012 Olympic cycle, I noticed a pattern: some athletes improved rapidly, whilst others on the same training program - similar age, experience, calibre - stagnated. Same training, different results. But why? 🧵👇 Athletic performance at the highest level is complex. Years of training build adaptations to enhance performance. Principles like progressive overload, periodization, and specificity guide our training philosophies and approaches.
