15. Lateral raises
Keep a small bend in your knees and lean slightly forward. As a goal try to complete 3 sets of 15 reps, with 30-second rest.
STEPS:
1. Stand with a straight torso, grab a 1-liter water bottle in each hand with palms facing inward, arms hanging at your sides.
2. Raise your arms out to the sides until they’re at shoulder level.
3. Pause, then lower the weights back to the starting position.
