#6 Crunches
Dubbed as the most popular exercise, crunches are wonderful for strengthening the core and toning the obliques.
Instructions:
Step 1: Lie on the floor in a supine position and place your hands behind the head without interlocking the fingers. Bend your knees such that they form an 'inverted-V' with the floor while ensuring that your feet are completely rested on the ground.
Step 2: Slowly lift your upper body without raising the hips until the shoulders are above the chest.
Step 3: Hold the contraction for a second and return to the initial position. Ensure that you complete the rep in a controlled motion for maximum efficiency.
Repeat the exercise for the recommended number of repetitions.
Important tip: Perform advanced variations of the crunch such as the bicycle curch or reverse crunch for an added challenge and improved resistance.
