What does a stationary bike do for you?
109369
stationary biking burns off calories at about 230 calories per hour.  it is a target exercise for your legs, buns and hips, usually done to develop muscles in your calf, trim and make your thighs leaner, firm up your butt (especially if you try doing some stand-ups while pedalling).  not only does it target your leg area, it also serves as another cardiovascular workout especially if paired with a treadmill or step workout.

I think exercise is a hassle too. Buy an exercise bike and put it in front of your t.v., so anytime you'd be sitting watching the tube, exercise on your bike instead.

I am an "ordinary cyclist", maybe even less than "ordinary" and it works for me.  I use a rim drive trainer with a mountain bike.  Extremely boring though.

Oooh, I'd be careful with that.  You should really speak with a doctor, preferably an orthopedist about that.  I'd say "yes" to things like riding a stationary bike or other low impact exercises.  I'd say "with care" to things like weight lifting, running, aerobics, etc.\n\nWhy don't you give spinning a try?  I just took that up recently and love it.

A bicycle stays upright when it is steered to keep its center of gravity over its wheels. More precisely, it stays upright when it is steered so that the ground reaction forces (vertical and horizontal) exactly balance all the other forces (or accelerations, depending on the reference frame used) it experiences such as gravitational, inertial if in a turn, and aerodynamic if in a cross wind. This steering may be easily supplied by a rider, or in certain circumstances, by the geometry and mass distribution of the bicycle itself.3\n\nLock the steering of a bicycle and it is virtually impossible to ride. Cancel the gyroscopic effect of rotating bicycle wheels by adding counter-rotating wheels, and it can still be easily ridden. This self-stability is generated by a combination of several effects that depend on the geometry, mass distribution, and forward speed of the bicycle.\n\nA factor that influences how easy or hard a bicycle will be to ride is called ‘trail’, the distance by which the front wheel ground contact point trails behind where a line through the steering axis intersects the ground. In traditional bicycle designs, with a steering axis tilted back from the vertical, trail causes the front wheel to steer into the direction of a lean, independent of forward speed. This can be seen by pushing a stationary bicycle to one side. The front wheel will usually also steer to that side. In a lean, gravity provides this force.

as a general rule, I would think that the exercise bike is going to be do more and still be gentler on your knees in the long run than a 30 minute walk.  Now a 30 minute run, that's something else.  if you don't feel that you're sweating enough, then perhaps you are not peddling as fast as you can.  If you feel that you are peddling fast, then perhaps you should try to see if you can increase the resistance of the bike.  it's also possible that you're working out your upper body while walking (swinging your arms or using weights?)  It's hard to make a judgement without more details.\n\nYou can also just check your heart rate after the 30 minutes of doing each.\n\nJust remember though that in terms of absolute calories, both the walking and the cycling probably will not burn much in the immediate scheme of things.  What you're working on is continued exercise - frequent walks and bikes over a long period of time (weeks, months, years).  This will build up muscle.  In doing so, you're looking to increase your overall basal metabolic rate (BMR) so that you burn more calories while NOT exercising (resting energy expenditure).  This is when you will start to see significant weight loss.  \n\nConsequentally, your heart rate may decrease as you exercise more as your body gets more fit for the same amount of exercise.  If you want to continue to increase your heart rate, you'll have to increase the intensity of your workout - jogging/running or faster peddling.

All I can think of...\nGravity (weight of bike + person), friction (of ground and all axles), pedal force (not constant because you are pushing on an arc), air resistance, inertia (this is why it gets easier to pedal once you get to constant speed), sprocket ratio, gyroscope effect (makes it easier to balance).

Bicycles these days have things like index shifting, this develpment has made cycling much eazer for the beginer. Back in the old days, "the 70's", I had to learn to shift by feel. This led to a lot of looking down and back, while working the shifter levers," once rode head on into a parked car doing that, even the people who owned the car were laughing". So you have the advantage of this wonderful index shifting. When approaching a hill down shift as you feel your legs begin to bog down, with index shifting you can down shift 1 gear at a time untill you reach the top of the hill. As you become stronger you'll down shift less. What you want to do is keep a steady cadence," RPM of the cranks", and use the different gear ratios to fit the terrain.

Forget spinning indoors.  Get a road bike and get a real workout!!! :-)

pick a gear where you dont have to pedal that hard, you want to use your body weight as a counterbalance...lean back and pull up your handlebars hard...after a few tries you will pedal longer.\n\nif you pull up too hard or lean back to far,your bicycle will flip out from under you..its all about balance...it doesnt come to you overnight but with work and practice you will know how hard to pull up and how far to lean back.

no "physical" energy is lost ihe bike is there, your there, etc..\n\nyou become tired due to buildup of acids in your muscles . lack of oxygen and hydration.

all depends on what you wish to do with it.\nAbout 20 years ago when i was into BMX racing , my choice of bike was the light weight "redline"

Well your working out your leg muscles and all of that. So I do believe so. It def. keeps you in shape if you do it all the time. I ride my bike all summer long and I feel great afterwards! So yeah you can def. loose weight from it... but you gotta make sure your legs start to hurt and feel that pain to know it's working, lol!

The easiest way to do this would be to remove your chain. This will let you pedal and not go anywhere. You will have to find a way to make the bike stationary so you can keep your balance while you're on it. I suggest removing the front tire and building a stand to prop the front tire frame in.  Make the stand level with the back tire so it will be exactly like riding a bike when you are on it.

get on a treadmill for about 15 min a day and a excessive bike for about 20 min a day, and go as hard as you can and when you get use to it, up the time and pace :)

Yes it turns fat into muscle.!!!\nCycling is one of the best forms of exercises that you can do,good for the lungs and loosing weight.!!!\nNever seen a fat cyclist.!!!

A pedal powered bicycle;\nYou get sweaty on a hot day and that's not a good thing if you plan to stop at a restaurant and flirt with the waiter/waitress.\nDogs can catch a bicycle. (At least when I am riding it)\nSteep uphills are a pain, and downhills are scary unless you have really good brakes.\n\nOn a motorcycle;\nHMMM,\nDon't rush me I'm thinking.\nHMMM\nHey I'm trying here......\n\nNope, can't think of one bad thing about riding my Harley.\nSORRY>>>>>>>>>>>
