do you enjoy running?

I never did before l liked walking but for my fitness I did look into running. It is described as the worlds most accessible sport.

my dad and my niece both really enjoy it.  I haven't been able to do it b/c it is really hard impact sport and i have a bad back

It is such a contrast to walking where one foot is always in contact to the ground and legs are kept mostly straight.  What sports are good for you to do with your bad back?

low impact sports such as biking or swimming

Now swimming is something I love and I know its great exercise but my doctor keeps going back to running reminding me that it helps with muscle elasticity and springy tendons.

I'm sure that is very true.  Its great for some people who can handle the constant banging on the joints
