Brenda Song was spotted entering then leaving her Studio City gym yesterday.
Just look at the pics of her walking into the gym.
She's got her hoodie on, and is all organized and ready to sweat.
Then when she's leaving, she's stripped down to just her undershirt and is looking pretty beat up!
Must feel GREAT!
There's nothing like a great workout to really make your day.
Way to work on your fitness, Brenda!
Check out some more pics (below) to see her before and after!
