Bike or walk?

I would do both...See which one you like the most.  But like others have said...It will never make up for a bad diet (simple carbs, a lot of oils and fried foods).  After my WLS I went from one exercise to another to find the right one for me.  I thought I would go back to tennis, racquetball, golf.  But a bad back told me not to!!  So I took up bicycle riding/walking and that has become my main form of exercise.  The bicycle; running errands (bank, coffee shop, pay utility bills, doctor/dentist appointments) is what I do now.  I'm retired so I have the time to do those things.  Brian

I think the stationary bike is better then walk for losing body fat fast...a person burns about 513 calories in a 30-minute run at 7 mph .so if u run one an half hour per day u can lose your body fat too fast.

Hi! To my mind, both ways can be effective, so, you need to try both and understand, which one of these - cycling or walking works best for you. You can start from walking. Normally, a person should walk for about 10 thousand steps a day, it's approximately 5 miles. Then, gradually, try to increase this number. There are even special fitness trackers that count the number of steps you've walked, the number of calories you've burnt, your heart beating and so on. A good way to start keeping track of your activities.

The same story with cycling, you can buy a bike and commute to work on a bike instead of using public transport. Or you can buy an exercise bike and train, without leaving your apartment.

All in all, I suppose the idea is clear. Good luck!
