What it communicates: You need to eat less pizza.

Similar to purchasing a cooking class, the repercussions of buying a fitness class or gym membership can be disastrous. We know you purchased that gift card to Soul Cycle with good intentions, but even the most secure woman might wonder if she should take your purchase as a hint.

Do you understand her passion for the raw energy of a group of sweaty bodies pumping away to trap music, or are you just upset with her muffin top?

For a fitness-freak or a marathon-addict, this may be an ideal gift. She'll be pumped to try a new workout and appreciate your thoughtfulness. But if she's never stepped into a gym in her life, expect her to go Alex Forrest on you. We wouldn't blame her.
