Should I ride everyday or not?
++ no, I don't
I think they say your muscles wont grow if you ride everyday cause it never gets any time to heal.
++ this is true especially for weight training, but cycling is different. It still helps the muscles to rest, sometimes for 48 hrs.
I weight 275, should I focus on building leg muscle or losing weight to help me ride longer?
++ ride one day, walk another, then ride ... alternate
Which would help me ride longer, leg muscle or losing weight?
++ stamina is a whole separate animal. I think practice builds stamina
I get tired going uphill in the lowest gears, is that cause of my leg muscles or im not in good fitness?
++ if hills weren't difficult, they wouldn't be hills. the better you get at technique and the longer you ride, the better you will handle the hills. but the hills will always be challenging. besure your bike fits and that your saddle is at the correct height
My legs feel bad if I push myself too hard and the next day they still feel sore, should I only ride when they feel normal?
++ rest is good :-) rule #1 is do no harm
Its also easier for me to go in a high gear in a lower cadence then a low gear in a high cadence,I guess my legs are in better shape then my heart and lungs.
++ I think has to do with your specific body type and build. some people with very large legs have a tremendous amount of power, and so you can use a bigger gear than a slender biker, regardless of how fit he is or how experienced he is. that said, he might still beat you in a race! :-)
