Get Washboard Abs With This 5-Minute, No-Equipment Workout

"This my favorite ab exercise to start with because I like warming up the lower abs first," said Erica.

• Lie on your back on the floor. Place your hands on the floor beside you.
• Bring the knees in toward the chest with your feet together.
• Use your abs to slowly curl the hips off the floor and into your chest, then slowly lower them back to the starting position to complete one rep.
• Keep your core tight and move with control. Do as many as you can for 60 seconds.
