If you suffer from back pain — or want to avoid it altogether, you’ll need to strengthen your core.

Strengthening your core is what allows you to do those everyday tasks (i.e. carrying the groceries, bending over to pick something you dropped, moving boxes, etc) and not get hurt doing them.

Plus, strengthening your core will give you better posture and keep you mobile well into your “Golden years.”

Here are three exercises you can do everyday (best of all, you can do them in as little as 12 minutes!):

Superman – Lie on your stomach. Stretch both your arms out in front of you. Make sure both your legs are straight behind you. To do a rep, lift your head, chest, arms and legs off the ground. You’ll feel your lower back tighten. When doing it correctly, you’ll look like Superman flying through the air. Hold this position for 3 – 5 seconds. Now go back to the starting position. Repeat 10 times.

Plank — Lie face down. Now get into a pushup position. Lower your forearms so that they are touching the floor. Keep your legs straight behind your. Only your forearms and toes should be touching the ground at this point. Now tense your abs and keep your back straight. Hold this position for 10 – 20 seconds. Repeat 5 – 10 times.

Side Plank- To do these, lie down on your right side. Now bend your right elbow, palm facing down. Put your left leg on top of your right and make sure they’re stretched out. Now lift your body (like you did in the plank) except this time, all that should be touching the floor is your right forearm and right toes. Stretch your left hand out towards the ceiling. Hold for 10 – 20 seconds. Repeat 5 times and then do the same on the left side.

Don’t worry if you can’t do all three exercises as outlined here at first. If all you can do is one rep, that’s fine.

Gradually build up. But most importantly, make sure you do these exercises every day to build a strong core that’ll help you relieve back pain, prevent future injuries and keep you walking taller.

Strengthening your core is just one of many things you should be doing to keep yourself fit and healthy.
