Stretching is an important part of a cool down routine as during exercise, our muscles become fatigued and tighten. Here are two amazing stretches that can easily be incorporated into any post-exercise cool down:
1. Hip Flexor Stretch
When you’re in a standing position, your hip flexors lift your leg to step up onto something. If you’re lying down, your hip flexors can lift your legs or lift your torso to sit you up. Your hip flexors are made up of muscles such as your iliopsoas (psoas muscle and iliacus).
Keep these flexors flexible to enjoy continued back health!
How to Stretch Your Hip Flexors:
Kneel on the floor (with legs bent), and rest your shins on the ground. Then, take one leg and lunge forward so that the leg is bent at a 90 degree angle. Ensure your knee is not going over your toes. Watch the below video below from

2. Hamstring Stretch
The hamstrings are made up of three different muscles: biceps femoris, semitendinosus, and semimembranosus. This muscle group is generally known for knee flexion and hip extension. Tight hamstrings are a common discomfort.
How to Stretch Your Hamstrings
Note that you’ll need the help of a friend for this stretch!
Start by lying on the ground, legs straight. Lift one leg straight up, and with the help of a friend, have them hold your weight (so your leg can relax) and push gently until it is uncomfortable to go any further. You can hold this stretch for 45 seconds to 1 minute before switching legs.

Things to Keep in Mind
Studies have shown that static stretching before exercising may not be beneficial and can lead to injury. When you’re gearing up for a good stretching session, do it after your workout as part of your cool down, or before you’re getting ready for bed. As an added mental bonus, just 10 – 15 minutes of stretching will help to relax and calm your mind!
If you ever feel as though you have pulled or strained a muscle, remember not to stretch it. When you strain a muscle, you’ve likely over-extended it, so re-extending it with stretching will have a negative impact on your recovery.
According to fitness expert Peggy Hall, “Stretching increases your blood flow and circulation for a healthier body and sends oxygen to your brain for a clearer mind and sunnier moods.”
