Not all freestyle kicks are the same 🦵 1️⃣ Small and fast Best for sprinting and short distances. High rhythm, high speed. 2️⃣ Slightly bigger and more relaxed Often a better option for longer swims and open water. Less energy, more sustainability. 3️⃣ Too big and too slow ❌ This is where many beginners go wrong. The legs create more drag, the body becomes unstable, and propulsion drops dramatically. A good kick doesn't need to be big. It needs to be efficient. #CapCut #beginnerswimming #adults
