I'm really into Cardio workouts.

I have a stationary bike, an old one. (really difficult to move pedals, hard on legs)

Now is this good for cardio ?

The thing is. I know that on a treadmill I can run for an hour at least. I have great stamina and currently am in pretty good shape.

The thing is, on my staionary bike I can only go for about 10 minutes.

Its not that I get really tired overall, but my legs are killing me so much that I just have to stop.

I am abit tired, but its mainly my legs.

So I was wondering, what is this really helping ?

What else can I do which would be better for my whole body ?

I just feel that maybe on the staionary bike its mainly my legs.

I know for a fact that on a treadmill I can run for over an hour.

I dont have much time in the day though, and the gym is quiet abit far from me.


I do about 2.5km each day on the stationary bike.

Thanks for any help.
