Hello. New here. If this is the wrong forum, I apologize.
I started riding about 3 months ago. I'm not really sure what the proper 'category' for what I'm doing is. I have a mountain-ish-bike but I ride around where I live, which is a heavily-populated, urban area (i.e.: pavement). Also of note, I know nothing about nothing when it comes down to bikes. I just pedal.
I have a question about what is the proper posture for your buttocks when riding, which I have a hard time putting into words, so bear with me.
I find that there's quite a bit of an angle for your lower back/hips to move once you're actually seated on the saddle.
I read somewhere that your back should be 'arched like a bridge', so I thought of sort of pushing my lower back 'forward', which seems to flex/lock part of my abdomen and my butt. While this feels like a somewhat unnatural way of riding, it actually looks like the 'arched like a bridge' thing. I can ride this way without too much discomfort, but I do find my legs getting tired more easily this way.
The other end would be to stick your butt out, which just seems to put a lot more pressure on the peritoneum (sp?) area and me no likey. In turn, this would make your chest droop forward, which also doesn't seem like the proper posture.
The third option would seem the most natural way to sit, which is just making sure you're sitting on your *forgotthename!*bones and riding. Not much to say about this one, just sit on the bike. I found this way to be less exhausting on my legs, but I do get some increasing discomfort as I ride longer and longer. Nothing too major and more a feeling of "Okay, gotta get off the bike now, enough for today", which may just be due to lack of training.
Anyways, I looked and looked, but no one really seems to mention this bit about how to sit.
I guess my questions are, does any of this ring a bell to any of you, guys? Is it just a matter of personal preference? Is any of these the 'proper' way to actually sit on a bike?
Sorry for the bad grammar and extension of the post. English is not my first language, so it's kinda hard to put things into words.
Thanks in advance!
