Amy Rosoff shared the 24-year-old singer is also fond of Pilates, reported Female First.
"Selena loves yoga, arm dancing, and Pilates. We like to do lots of butt toning too. If you keep your same old routine, you will most likely get bored and wind up skipping the gym.
"Working out should be a part of your lifestyle, not an obligation or burden. Make your workouts fun by keeping it fresh and doing something different each day. Selena and I do everything from Pilates to hiking to dance cardio to circuit training to yoga and spinning - the list goes on," Rosoff said.
