Step 1: Start position
Sit on a workbench or a chair if exercising at home. Make sure your feet flat, hip-width apart. Hold the bottles of water just above your shoulders.
Step 2: Lifting and lowering
Push your arms upwards towards the ceiling. Then lower them back to the shoulders to complete one repetition. Repeat this movement 10 times.
Step 3: Breathing
As you raise your arms breathe out and as you lower them breathe in.
Step 4: Review
Once you are familiar with this exercise, repeat it for 10 repetitions.
