Video transcript
If you're squeezing cycling into a busy schedule, you're training hard but hitting frustrating plateaus or always fading late on longer rides, you're definitely not alone. Juan faced the exact same challenges. In just 6 months, he boosted his threshold by 55 watts and dropped nearly 9 lb or 4 kg in the last 2 months. But more importantly, he shifted from burnout and frustration to renewed strength, confidence, and enjoyment on the bike. Today you'll see exactly how Juan made these sustainable improvements and how structured training could help you finally break through your ceiling and cycling plateau. But first, let's quickly meet Juan himself. Here's why he decided to reach out to me as his coach and the biggest difference he's noticed so far. I wanted more structure, guidance, uh, and a plan that actually fit with my goals and lifestyle. Since starting, I would say the biggest difference is how every workout just feels purposeful. I'm not just riding hard for the sake of it anymore. Six months ago, Juan was burnt out. He was frustrated and he was stuck at around three watts per kilogram at his threshold. And despite more than a year of initially promising training, one's progress had completely stalled. Every ride was draining, overly intense, and left him more tired without improvement. He knew something had to drastically change. Does that sound familiar? The first big shift we made was introducing structured training, targeted intervals, carefully planned endurance rides, and deliberate recovery days. Progress wasn't immediate, but for the first time in ages, one started seeing sustainable improvements. Now, let's jump right into one's training calendar on Training Peaks and break down exactly how we structured his first three and a half months leading up to his first big event. an event that, by the way, changed his entire cycling trajectory. But more on that in a moment. Phase one, building the base weeks 1 to four in January. Average 4 hours, 45 a week, mostly zone 2 with general strength. The aim is mitochondrial biogenesis and a biggest drug volume. In other words, building a steady aerobic foundation with a couple of exceptions like the V2 max, the 4minute intervals. 4x4 minutes at 110% of critical power with equal rest. They are for central adaptations and boosted stroke volume. And I'll admit these were a little too hard at this early stage and something I will be changing going forward. But note I do sprinkle in these small doses of every intensity zone in each block. So we maintain those energy systems. We prevent draining and we avoid a rude shock when it comes to training that zone later on. Phase two, aerobic ramp up in weeks 5 to 8. In February, volume jumps to 8 hours. Longer zone 2 and three rides to push fat max and grow capillary density. We boosted endurance and early durability. Fitting in rides like this, a lactate threshold session of four sets of 8 minutes at nearly 95% of critical power, riding close to the second lactate turn point while holding a blood lactate at around 4 to 6 millm moles per liter. And this helps the glycogen cost stay under control. Phase three, extensive aerobic development. Weeks 9 to 12. In March, a 7-hour average and a planned no bike holiday. Glycogen sparing work plus cross trainining kept chronic load stable. And real life happens. We adapted and then we moved on to phase four. And in phase four, this was a gamble after the break, but I wanted that extra top end percent to test one's response. We did race specific intensity in weeks 13 to 16 in late March into April. 8 and a half hours a week with V2 max blocks and anorobic efforts. The V2 lifts central ceiling while the anorobic works helped build power and capacity over threshold. Then came race day, one's first big test. Despite all of this structured preparation and the numbers moving in the right direction, Juan finished far below his expectations. He felt sluggish and heavy and he was deeply disappointed. But here's the thing. This disappointment was actually the critical turning point. One realized something essential was missing from his training, and that was nutrition. He took full initiative eliminating junk food, cutting out sauces, properly fueling before and during rides, and dramatically reducing alcohol intake. These simple but challenging dietary changes started showing incredible results very quickly. But the real difference maker was consistent, purposeful training. Each session had a specific goal. Addressing one's weakness, building fatigue resistance, and gradually increasing muscular endurance. We reset one's focus toward his next events, building his fitness methodically from the bottom up, building endurance capacity and durability in week 17 to 24. This is late April through to June. One, consistently hit nearly 10 hours per week. And we went from building on bike strength to rebooting his endurance training. significantly. This was boosting fatigue resistance and durability. This structured, methodical approach led to consistent improvements. And before you say this was probably too much, let's take a look at the actual hours because it's not as many as you might think. In total, once structured training came to around 154 hours, averaging roughly 7.7 structured hours per week. Let's quickly recap those numbers visually. We have weeks 1 to 4 and then we have weeks 5 to 8. Then there's weeks 9 to 12 including the holiday break. And then there's weeks 13 to 16 and weeks 17 to 20. Now let's hear from one again. Here's the exact moment when he realized that this structured training was finally working and how it felt for him. moment I realized the training was really working for me was with these harder group rides in the area. Before I was training with Damian, I would struggle just to keep on the wheel some of these more experienced riders. Uh now I'm able to contribute to these group rides. So being in the front taking pulls, etc. The most exciting results is just seeing my FTP uh steady steadily climb. Uh especially after putting so many hours in the saddle, it's nice to see your work pay off. So what were the overall results of one's structured training and nutrition? In short, remarkable. He lost over 4 kg, nearly 9 lb purely from dietary changes, dropping from 73.6 kg to 69.3. He gained 55 watts of critical power, increasing from 223 to 278. And his watts per kilogram surged from 3 to 4. But perhaps even more exciting, one's durability dramatically improved. His 5minute power before at 1,000 kJ improved from 262 to 308 watt. His 5minute power after 1,000 kg improved from 216 to 283 watt. His fatigue induced power loss decreased from 46 watts down to 25 watts. That's a 46% reduction. Beyond these powerful numbers, one also experienced important personal improvements. Group rides felt easier and more enjoyable. sustained efforts became comfortable and achievable and his overall pacing, nutrition management, and strategy significantly improved. One's transformation isn't unique. These results are achievable for anyone that's ready to commit to structured, consistent training and intentional nutritional changes. Ask yourself honestly, do you see parts of one story in your own cycling? Are you ready to break through your own barriers and unlock your cycling potential? The truth is structured training works and you can achieve these kinds of sustainable improvements, too. Check out the links below to see how Senipro can help
