6 Intense HIIT Workouts For Abs And Obliques

#4 Mountain Climber

The mountain climbers not only target the core, but they also activate a host of muscles in the upper and lower body, making it a full body exercise.

Instructions:

Step 1: Lie on the floor in a prone position and transition yourself into a plank such that the body rests on the toes and palms. Ensure that the arms are fully extended throughout the duration of the exercise.

Step 2: Explosively bring your left knee towards the chest while keeping a stationary torso.

Step 3: Hold the contraction for a second and return to the initial position. Perform the same motion on the other side to complete one rep.

Repeat the exercise for the recommended number of times.

Important tip: People with a history of knee pain must exercise caution while performing the mountain climbers.
