Differences Between Working Out in Your 20s and Your 30s

Butts:
20s: What can I do to make my butt look smaller?
30s: Bigger the better. Bring on the squats!

Postclass:
20s: Leisurely hit the sauna, take a long shower, then meet up with friends for a splurging dinner out.
30s: Bolt out as soon as the class is over to relieve my significant other or sitter.

Post-Workout Fuel:
20s: Let's head out for a beer, 'cause whatevs!
30s: Love me my homemade energy ball and coconut water.
