Quote[/b] ]Lower Back Stretches
These stretches work mostly the lower back, but also make some demands on your abdominals, and your external obliques (sides).
Lying down with your back on the floor, straighten one leg, while bending the knee of the other leg, and try to bring the thigh of your bent leg as close as possible to your chest. Hold it there for 10-15 seconds. Then cross your bent leg over your straight leg and try to touch your knee to the floor (while trying to keep both shoulders on the ground). Repeat this same procedure with the other leg. Then, bend both knees and bring both thighs up against your chest (keeping your back on the floor). Hold that for 10-15 seconds. Then, put both feet on the ground but keep the knees bent. While trying to keep both shoulders on the ground, roll your legs over to one side and try to get your knees to touch the floor beside you. Hold for about 10-15 seconds and then do the same thing on the other side. Now repeat the same stretch, but this time begin with your feet off the floor so that your leg is bent at the knee at about a 90 degree angle.
As for isometric stretches for the back, I don't recommend them.
What exercises strengthen your back, particularly your lower back?
The lower back is an area that's often ignored but frequently causes problems, especially as the years go by. Strengthening exercises, as well as stretching, help prevent injury and pain. It's important to focus on the lower back muscles as well as those in areas that support the lower back. These include the stomach, hip flexors, and hamstrings (back of the thigh).
Let's first concentrate on your lower back muscles. Begin by performing a front lying chest lift, a body weight exercise that involves no equipment at all:
1. Lying face down, place your hands (palms down on the floor) next to and even with your chest.
Keeping your hips and thighs on the floor, lift your chest off the floor. Assisted slightly by your arms as you lift, your lower back muscles should be contracting. Make sure the back of your head is in an even line with your spine — don't tilt your head up or down. Pause briefly when your arms are straight and then return to starting position. Build up to three sets of eight to twelve repetitions, taking short breaks between each set.
If you have access to a gym, the low back machine allows you to increase resistance as you become stronger. Try resistance exercises two or three times per week on non-consecutive days:
2. Sit on the seat with your legs secured and upper back in contact with the roller pad. Push the roller pad down towards the floor, contracting your lower back muscles. Your range of motion should be comfortable. Pause briefly and return to starting position slowly. Keep your arms relaxed and your head in a neutral position. Use a weight that allows you to complete two or three sets of eight to twelve repetitions. You may stretch every day once you've warmed up your muscles. Stretch smoothly, as opposed to bouncing, which can cause injury. For maximum effectiveness, each stretch needs to be held for at least fifteen to thirty seconds. Excellent lower back stretching exercises include:
3. Double knee to chest stretch - Lying on your back with knees bent, pull both knees off the floor toward your chest, holding legs behind the knees on the bottom part of your hamstrings. This stretch can be done with both legs together or one at a time.
4. Figure-4 stretch - Lying on your back, with your head on the floor or mat and right knee bent, pull your right knee towards your chest. Then draw your knee across your body towards your left shoulder. Try to keep both shoulders on the floor or mat. Repeat with your left leg.
5. Cat/Cow stretch - On your hands and knees, sag your back while lifting up your head. Alternate with arching your back and keeping your head down. Lean back onto your heels and hold, keeping your head down and arms extended.
6. Abdominal muscle-strengthening stretch - Correct form is the most important aspect of this exercise, which will support your lower back: Lie face up with your knees bent and your hands placed loosely behind your head. Slowly curl your upper back off the floor while pressing your lower back against the floor. You should feel your abdominal muscles contracting. Pause briefly before returning to starting position. Try your best not to put pressure on, or pull, your head with your hands. Keep your breathing coordinated: exhale on the way up, inhale on the way down. Don't rush — do this exercise slowly.
7. Hip flexor stretch (a.k.a. Runner's stretch) - Stretching your hip flexors can help alleviate stress to the lower spine: Assume a lunge position, making sure your front knee is directly over your foot and ankle (your knee will be in the form of a right angle). With your weight supported by both hands touching the floor, press your hips towards the floor. Repeat on both legs.
8. Hamstring stretch (Straight leg raise) - This exercise will also help reduce stress to the lower spine: Lying on your back, bend your knees and keep both feet flat on the floor. Raise and straighten your right leg without lifting your hips from the floor. Support your leg and increase your range of motion by placing your hands below your knee, around the back of your leg, and gently drawing your leg towards your chest while keeping it straight. Repeat with your left leg.
Hope these exercises and stretches keep you in tip-top shape and pain-free.
You can also choose structured exercises for strengthening your back. Yoga, for instance, is an excellent form of back strengthening physical activity. Many of the suggested stretches listed above are a part of poses and movements performed during a yoga session. Swimming is another excellent exercise for your back because the buoyancy of the water offers some support.
Also, notice your posture. What position do you spend most of your time in when you are sitting, standing, and walking? For example, does your job require you to sit at a desk throughout the day? If so, be aware of your posture. Make sure the ergonomics of your work set up are optimal for your body. If you have freedom to play with your workspace, consider using a balance ball as a desk chair even for part of the day. Sitting on a ball demands your posture to be proper and many of your torso muscles to stay active.
Point: you have many opportunities during the day to tend to your back. Tend well.
