Are You Willing To Follow Eight Yoga Exercises For the Lower Back?

exercises FOR BACK RELIEF

Many people believe that rest is best for a painful back, but actually, what your back really needs when it’s hurt is exercise. Regular exercise relieves back pain by strengthening and stretching the muscles that support the spine and helps to prevent future injury. This is a use it or lose it situation: the more you rest, the weaker your back gets, even if it is hurt. Studies have actually shown that you can heal your back pain faster and get back to your regular activities with just two days of rest. This article will focus on Yoga exercises. Remember to contact your doctor before beginning any exercise program.

YOGA exercises FOR YOUR BACK

A good, regular yoga practice will go far in relieving the stress and tension that sometimes cause mild back pain, and in fact, studies have shown that yoga is the number one most effective exercise for relieving back pain. However, not all yoga poses relieve back pain, and some can in fact aggravate existing pain, so it is important to know which poses will be most helpful in relieving back pain. It is best to do these exercises under the supervision of a certified yoga instructor, and if you encounter any problems with these poses, you should consult an expert. Even just one or two sessions with a yoga instructor can help, as an instructor will help you with your form and posture during poses. Here are some of the best yoga poses for relieving back pain. Each pose should be held from five to ten seconds, depending upon your level of comfort, and should be done on a mat or other soft, supportive surface.

CORPSE: Lie flat on your back in a relaxed position, arms resting at your sides, palms down, and legs lying naturally, with knees turned out slightly. If it hurts your back to have your knees turned outward, do this pose with knees bent, feet flat on the floor. Breathe in and out for a few seconds while allowing any tension to leave the body.

CAT STRETCH: Start out on your hands and knees with a flat back. Your hands should be directly under your shoulders with fingers spread. Knees should be directly under the hips. Head is held loosely so that you are looking at the floor between your hands. Inhale, and as you exhale, arch your back toward the ceiling, tuck your chin in to your chest so that you are looking at your navel, and tuck your tailbone underneath. Hold, then release back into your original position.

WIND-RELEASING pose: Lie flat on your back as in Corpse pose. As you inhale, bend your knee, place your hands right below the knee, and draw your leg towards your chest. Your left leg should remain flat on the floor. Exhale and bring your forehead up to touch your knee. Inhale, and then as you exhale, return to your original position. Repeat with the other leg.

SAGE TWIST: Warning for this pose—it involves twisting your back, so you should take particular care not to twist too far or you risk aggravating any existing back pain. This should be a gentle stretch; twist just as far as is comfortable. Sit on the floor with both legs out in front of you. Bend your right knee, lift your right leg over your left, and place your right foot on the floor next to your left knee. Sitting with spine straight, place your left elbow on the right side of your right knee. Bend your left arm so that your left fingertips are touching your right hip, while at the same time, twisting to look over your right shoulder. This is where you need to be careful not to twist too far. Hold for a few seconds, release, and repeat on the opposite side.

PALM TREE: stand with feet facing forward, arms at your sides, weight distributed evenly on both feet. Raise both arms over your head, interlock your fingers, and turn your hands so that your palms are facing upward. Next, place your palms on your head and turn your head so that you are looking slightly upward. Stretch your arms upwards, and at the same time, come up onto your toes if you can do so without pain. Stretch your entire body upward and hold, if you can. Some people have difficulty balancing during this pose, so just do the stretching part if you need to.

FISH pose: Lie on your back with knees bent and arms at your side. Arch your back as far as you comfortably can and raise it off the ground by pushing the floor with your elbows. If you can, tilt your head backwards and rest the crown of your head on the floor. Breathe deeply from the diaphragm and hold pose for one minute if you can.

LOCUST: Lie face down with arms at the side, palms down, and elbows slightly bent with fingers pointing towards the feet. Raise your legs and thighs as high off the ground as possible without causing your back any pain. Hold for one second and repeat up to twelve times. This can be a vigorous exercise so you must take care to strain already injured muscles.

BENDING FORWARD posture: stand up straight with feet together and arms hanging loosely along your sides. Breathe in deeply and raise your arms straight above your head. While breathing out, bend forward and touch your toes if you can. If you can’t reach your toes, grab hold of your ankles or calves. To complete the pose, you should touch your head to your knees, but this may be too difficult for many who suffer from lower back pain. Your movements during this pose should be smooth, not jerky.

Hard Drives

A hard drive, or hard disk drive (HDD), is the storage device you use in your personal computer (PC). These are non-volatile storage devices used to store the data of your computermeaning you can be assured that whatever data is stored in these devices, it cannot easily be erased. However, there is no guarantee that your hdd would not encounter problems causing it to crash and causing you to eventually loose your data.

Inside the hdd, there are many mechanisms that move around to perform read and write functions. The hdd is made of rotating platters, commonly called disks. Each of these platters has a planar magnetic surface where the data is stored. This data is sent to a read-write head, which sends an electrical charge, executing the transaction. These moving parts and electrical charges could possibly cause the breakdown of your hdd, but manufacturers have already designed firmware into the hdd to allow more efficient scheduling of reads and writes if the hdd surface and the remapping of sectors of the disk fail. Also, hdd manufacturers have collaborated with motherboard makers in developing the Self-Monitoring, Analysis, and Reporting Technology, or S.M.A.R.T., that can warn you of possible failures, allowing you to make necessary backups before data loss occurs.

An hdd is accessed with the following bus types: ATA (which includes IDE and EIDE), SATA, SCSI, SAS, FireWire (or IEEE 1394), usb and Fibre Channel. Aside from the connection, you have to select your hdd by the capacity, nowadays measured by gigabytes; the physical size, normally, if you are using a desktop, you would need a 3.5 hdd, whereas 2.5 is what you would use for a laptop; the reliability or the estimated number of uses before you hdd fails; speed or the number of reads and writes per second; power consumption; transfer rate; random access time; and the G-shock rating, which is very important if you plan to travel with your hdd a lot.
