I'm sitting behind a gal the other day in spin class and I notice (as I'm apt to do) that she is quite lean - almost scarily so. After the class, as she was wiping down her bike, she commented to her friend that she found another great way to work out.... right after her spin class, she hops in her car to a kick boxing session! Yikes! Don't get me wrong - I like working out a lot but to me that is veering on excessive.
And it made me recall another gal, almost skeletal, who made a practice of doing back-to-back classes at my sister's gym...is this becoming more common do you think?
Question: Would you mention your concern or think it is none of your business?
