10. Mountain Climber
Doing the mountain climbing exercise is truly a challenge, but is considered one of the best ab workouts.
How to do it: Start out in a high pushup position with your hands on the floor, shoulders straight, and fingers pointing straight ahead. Tighten your abdomen, and slowly bring your right leg toward your right shoulder. Pause for about 2 seconds. Then, gently bring your right leg back to its original position. Do the same with your left leg. Alternate legs until you complete the recommended number of reps.
So there you have it! Get in shape in the comfort of your home with these easy and effective ab workouts.
