aerobic exercises for weight loss

[navi]

1-He does aerobic exercises for weight loss.

Does that mean
a-There are certain aerobic exercises that are for weight loss and he does them
or:
b-In order to lose weight, he does aerobic exercises.

Gratefully,
Navi.

If we wanted to say "in order to lose weight", we would probably say "he does aerobic exercises to lose weight."

So it would probably have your meaning a. But theoretically, it is ambiguous.
