Break a mental sweat with this relentlessly relatable Unisex Jersey T-Shirt featuring the "Overthinking is my cardio" design. The soft, lightweight fabric keeps you comfortable through practice rooms, lessons, rehearsals, music camps, or simply a casual day out replaying conversations from 2014. This is for the certified mental marathoner, the 3 AM analyst whose brain runs laps while the body stays firmly on the couch. Musicians train hard for this event: you replay the one wrong note from Tuesday's concert, then the audition from six years ago, then whether the conductor's nod meant good job or we'll talk later. Heart rate elevated, no gym required. You're in excellent shape. Mentally, exhausted. Great for gifting during holidays, birthdays, recitals, or audition season, this tee resonates with musicians, perfectionist students, teachers, and anyone who appreciates both overthinker humor and comfort in their everyday wear.

As a violinist who replays every audition in her head for months, I have never felt so seen. Soft and fits beautifully.

good shirt, funny slogan, comfortable fabric. Only complaint is it runs a bit slim so I'd size up if you like a loose fit.

Gave this to my daughter before her college music auditions and it made her laugh instead of panic. She wears it constantly now.
