If you want to see that toned tummy you've been working for, you need to get down to basics and hit your abs and core muscles. According to Kendall, "the seated Russian twist is a great all-around core move that you can do anywhere."
- Lie on the ground with your spine flat on the floor and your knees bent.
- Using the power of your abs, pull your upper body forward so you're sitting at a 45-degree angle with the floor. Keep your back straight throughout this movement.
- Bring your hands together in front of your abs and twist your torso to the right. Pause for a one count, return to the start, and twist to the left. Pause for another one count before returning to the start again. That's one rep.
