In butterfly there are only two kicks. Not more, not less. 👉 The first kick happens when your arms exit the water. As your arms start the catch underwater, you begin the downward motion of the first kick. The goal is to finish the pull and the kick at exactly the same time. When you get this right, they create double propulsion together. You fly out of the water, your arms recover easily above the surface, and the whole stroke feels smooth. 👉 The second kick happens when your arms enter the water. This one is a support kick. It helps you maintain rhythm and set up the next stroke. ⚠️ But here's what most swimmers get wrong even when the timing is correct. The two kicks are not equal. ❌ If you kick with equal power on both, you lose the propulsion that makes butterfly sustainable. ✅ The first kick is your main kick. It has to be much stronger. ✅ The second kick just supports the movement. Nothing more. 🔑 First kick strong. Second kick supportive. Arms and legs finishing together on the first kick. Get that right and butterfly starts to feel completely different. 📲 Download our app to get your first 7 days of personalised training completely free.
