running is hard on joints, esp for heavier folks.

Running is actually good for your joints. You'll have a hard time finding studies saying otherwise.

Running is certainly usually harder for heavier folks, but being bad for your joints is not the reason.

>Running is actually good for your joints.

Running a reasonable amount (contextually defined), with good form, in appropriate footwear, ideally not on hard surfaces (i.e. concrete) can be good for your joints.

Just about anything done with poor form or in excess is going to cause issues. Not sure it's a useful point.

Depends on age. If you are under 40 running can be beneficial for joints. Especially if you start running at later age then it could cause problems.

If you very gradually ease into it. Add mileage slowly, it will not be. That is why you see plenty of larger heavier folks running marathons.
