Step 2: DON'T GO HOME
If you plan to sweat after work, don't kid yourself. I've learned that if you go home and sit on the couch for just one second, its gravitational pull becomes stronger than G-Force and you will literally be forced to lay there and watch Sex and The City re-runs, until you're found crying into a tub of BBQ chips the next day.
Pack a bag and haul it around like a badge of honor. ORRRRR, you can scratch this step and jump into...
Step 3: Meet The Incredible World of Athleisure
Athleisure: Athletic + Leisure. Duh. Basically workout clothes that don't entirely suck. Stuff you could wear on-the-go and have others wonder if you're just done working out, or if you're heading to. Messy buns encouraged, but not required.
I love sports bras from Forever 21, which aren't an expensive way to collect pools of sweat and hold your boobs in place. The leather-panel sweats are Betsy Johnson and the long sleeve runner is from New Balance. These sneaks are Keds (not ideal for running, but for low-impact workouts) and the black sequin top is from H&M (OKAY, THIS IS NOT A WORKOUT TOP, BUT IT'S HELLA CUTE, AM I RITE?!)
I also love my Polar Heart Monitor, helping me keep track of calories burned and my heart rate during a workout.
