You can swim easy for a long time.

Here's what's actually happening. When you swim easy, your body produces and removes energy at almost the same rate. It creates a balance. And that balance is what lets you swim for a long time without getting tired. 🔴 But the moment you push harder, that balance breaks. Your body starts producing lactic acid faster than it can remove it. Your muscles fill up. And you crumble. 👉 The fix is threshold training. 🔵 Threshold is the zone where you're working hard enough to produce lactic acid but your body is still removing it just as fast. You stay in balance. But at a much higher pace. 👉 Train in this zone regularly and two things happen. ✅ Your body gets better at clearing lactic acid faster. ✅ Your threshold pace rises. So what felt hard before starts to feel manageable. 👉 Here's what threshold training looks like in practice. 1️⃣ Target around 70 to 80 percent of your fastest pace. 🔵 Hard enough to feel uncomfortable. Not so hard that you fall apart after one rep. 2️⃣ Keep your heart rate around 140 beats per minute. ✅ That's your zone. Stay there as long as possible. 3️⃣ Use interval training to build it. ✅ For example, 8x200m with 30 seconds rest. Consistent effort every rep. Don't go out too hard on the first one. 🔴 This is especially important for triathletes. Your body needs to know how to work hard, clear lactic acid, and keep going. That's what threshold training teaches it. 🎯 Inside the Swim Success Training app threshold sessions are built into your plan automatically based on your pace and your goal. You always train in the right zone at the right time. Link in bio.
