I lift at least 3-4 hours a week - mostly single leg exercises but core and upper body are a facet as well, but I'm a sprinter so its a little more specific then just "healthy body strength lifting". In February I'll switch the time in the gym lifting my legs to sprint/interval styled workouts on the bike.
And yes I use intervals as my main training system when on the bike in the winter months.
Maybe I'm being misinterpreted here ... I don't think an endurance rider has any business thinking that a weight lifting program will give him more than just a general fitness baseline. However, I do think that a weight lifting program (when done correctly, and I don't think many ppl accomplish this) can give anyone a general fitness baseline AND as mentioned before help to erase strength discrepancies.
We've been over this before. Lifting can benefit endurance racers. Working strength can help with endurance. Do you have to lift? No, but it can help. And I hope you know, it helps for any bike racer to develop some kind of a sprint. Even endurance racers" cycling isn't a strict endurance sport.
No offense but when you talk about single leg lifts and core training I just don't think you know much about lifting or programing.
I'm not sure what says stupid about the phrase single leg exercises and core, vague maybe. I focus on primarily single leg lifts to make my training more specific to cycling. If I was younger I'd go into detail.
And about every cyclist needing a sprint? Yea sure I'll agree that everyone could use one. Except to get the strength from the gym that you'd need for a "sprint" it's not as easy as just going to the gym and lifting heavy.
compound lifts, like the squat and deadlift, are far superior to "single leg lifts". This is basic knowledge. Second, your "core" does not need to be seperatly trained. And when we refer to "core" most people think abdominal muscles. What is more important is posterior chain. The difference from a good and bad coach would be a good coach can tap into the spinal erectors, hamstrings, and other muscles into the lower body. All these muscles with abdominal region included are much more accurately referred to as the trunk.
and yes, you need to train right to get results. But if you've been reading the rest of the threads that's what we've been discussing.
