Shakira's Longtime Trainer Shared the Ab Exercises That Keep Her Shredded

Your glutes are a key part of your core, and Shakira strengthened hers with classic squats in one of her Super Bowl prep workouts.

• Start standing with your feet slightly wider than shoulder-width apart.
• Sit back and down like you're sitting into an imaginary chair. Allow your torso to hinge forward a bit, but keep your chest up and back straight.
• Pause when your thighs are parallel to the floor (or as low as is comfortable), with your knees tracking over your ankles. Press your weight back into your heels.
• Keeping your core engaged, push through your mid-foot to return to standing. That's one rep.
