The 32-year-old singer stepped out wearing the long sleeve silver shirt with gray sweatpants in Thousand Oaks, Calif. The waterproof top is designed to help make the wearer sweat profusely during a workout.
Ready for her trip to the gym, Spears had her long red hair pulled up in a high, messy bun. She was accompanied by boyfriend David Lucado. The Virginia native, who has been dating Spears for nearly a year, opted not to wear the sauna suit top and chose a simple black T-shirt instead.
The "Work Bitch" singer has to stay in shape to keep up with her busy schedule. Spears has been giving dance-intensive performances at her two-year Britney: Piece of Me residency at Planet Hollywood Resort and Casino in Las Vegas, but is currently enjoying a short break.
