Here are some simple muscle stretches that you can do between working hours to relax tense muscles.
1. Do it for the neck and shoulders
Slouching over the keyboard can stiffen the spine, neck and shoulders. To relax these muscles again, you can do this method, reach your arm through the back, then put your fingers so that your palms are facing. After that, raise your arms so that you feel a stretch in your chest and front shoulders. Meanwhile, to avoid a cracking neck, pull your shoulders down. This method you can do at your work desk (if your work space is quite busy) or if you feel cramped, you can do it on the toilet.
2. For the stomach
Reach for your arms and lean back slightly so that your chest and throat are pointing upwards. If you have trouble balancing, keep your gaze forward or at the floor. Then repeat this step on the other side.
3. Hip Flexor and Iliopsoa
Some muscle groups can be at higher risk of stiffness after a day of activities sitting in front of the monitor. For that, here are the stretches you can do after a day of work to keep your muscles relaxed. Kneel on the floor (with your shins on top and stiff as your base, then your torso straight). After that, lift your left leg then place it on the floor and hold your knee just above the ankle. Keep your hips horizontal as you move your body toward the wall in front of you, then slide your knees forward. While in this position, you may feel a stretch in the calf and achilles area. To support it, place your hand on your left thigh.
From flexor stretches in the hips (low lunge with left leg forward, right knee and shin on the floor) then reach your left arm to your side then touch your fingers to the floor or a pile of books to support this position. Then arch your right arm above your head until the tip of your right finger reaches the left position of your body. Then hold for about 20 seconds, breathing regularly. Then repeat the same thing by switching hands and switching legs.
Those are some simple muscle stretching methods that you can do to relax muscles that feel stiff and tense due to working all day and sitting in a chair all day.
