It’s flu season, and staying healthy is more important than ever. While washing our hands and staying home when we’re sick are important steps in preventing illness, physical activity can also play a role in keeping us healthy.

Here are some easy gymnastic moves you can do to help boost your immune system and keep the flu at bay.

1. Forward Bending

To perform forward bending, stand with your feet shoulder-width apart and slowly bend forward from your hips, reaching your fingers towards the ground. Hold the position for a few seconds before slowly coming back up.

This move can help stimulate the digestive system and improve blood flow.

2. Balancing on One Foot

Stand with your feet hip-width apart and lift one foot off the ground, balancing on the other foot. Hold the position for a few seconds before switching to the other foot. This move can help improve your balance and strengthen your leg muscles.

3. Arm Swings

To perform arm swings, stand with your feet shoulder-width apart and swing your arms in a circle, starting small and gradually getting larger. This move can help improve range of motion in your shoulders and upper back.

4. Squats

To perform squats, stand with your feet shoulder-width apart and slowly bend your knees, keeping your back straight, until your thighs are parallel to the ground. Hold the position for a few seconds before standing back up.

This move can help strengthen your leg muscles and improve your balance.

5. Hip Circles

To perform hip circles, stand with your feet hip-width apart and slowly move your hips in a circle, starting small and gradually getting larger. This move can help improve mobility in your hips and lower back.

6. Leg Swings

To perform leg swings, stand with your feet shoulder-width apart and swing one leg forward and backwards, keeping your leg straight. Repeat with the other leg. This move can help improve the flexibility of your hip flexor muscles.

7. Windmill Arms

To perform windmill arms, stand with your feet shoulder-width apart and lift your arms straight out to the sides.

Keeping your arms straight, slowly bring your right arm across your body to your left hip while simultaneously lifting your left arm straight up towards the ceiling. Reverse the movement, bringing your left arm across your body to your right hip while lifting your right arm up towards the ceiling. This move can help improve flexibility in your shoulders and upper back.

8. Knee Raises

To perform knee raises, stand with your feet hip-width apart and lift one knee up towards your chest. Lower your foot back to the ground before repeating with the other knee. This move can help improve balance and strength in your leg muscles.

9. Upper Body Twists

To perform upper body twists, stand with your feet shoulder-width apart and place your hands on your hips. Slowly twist your upper body to the right, then to the left. This move can help improve mobility in your upper back.

10. Plank

To perform a plank, start on all fours with your wrists directly under your shoulders and your knees directly under your hips. Step your feet back until your legs are straight and you are balancing on your toes and hands.

Hold the position for a few seconds before slowly lowering yourself back down to all fours. This move can help strengthen your core muscles and improve your overall balance.
