I don't know what grad school is - I have a masters degree in astrophysics and I have to say it required nothing like what you've described, so I suspect you're aiming for a PhD or something?

Balancing life and fitness can be very challenging these days, especially the kind of commitment required to achieve the lean and strong body shown here.

Good luck in your studies, I hope you find time for a healthier lifestyle soon!

BTW- the original poster mentioned the affordability, not the time issue. Hence why I said what I did.
