#5 Side Planks
The side plank improves spinal stability, as well as upper-body and core strength, with an emphasis on the obliques. The exercise also increases balance throughout the body and strengthens the shoulders, wrists and arms.
Instructions
Step 1: Lie on one side of your body with your legs stacked and fully extended.
Step 2: Now use your lower elbow and forearm to prop your body up in a side plank position. Remember to squeeze your abs throughout.
Step 3: Hold on to that position and then repeat on the other side.
Important Tips: Hold on for 60 seconds on each side respectively without a break. Remember to squeeze your abs and glutes and don't allow your hips to drop. Maintain a straight line from head to toes.
