Summarize the following:
Start by standing with your feet shoulder-width apart. Bend your arms at the elbows and push your chest forward so it begins to stretch your rib cage area. As you move your chest forward, move your elbows and shoulders back at the same time. This movement will stretch out your chest even more, which may result in your sternum cracking. Imagine trying to touch your elbows behind your back. That's the movement you should be aiming for! Bring your arms up so they're almost even with your shoulders, then bend your elbows. Twist your torso to the left as far as you can without straining, keeping your feet, knees, and hips in place. Then, twist all the way to the right. Repeat this process about 4 or 5 times, or until your sternum pops. This movement will help open up your chest, which can help your sternum pop. However, even if you don't hear a pop, you'll likely get some pain relief just from stretching. You can do this exercise while you're standing, or you can try it sitting down if you prefer. Hold one of your elbows at a 90 angle from your body, with your forearm pressed against a doorframe. Stagger your feet, then rotate your torso away from the doorframe, pressing in with your forearm to increase the resistance. Hold the stretch for 10-15 seconds, or until you hear a pop in your chest. Stop doing this stretch if you feel any tingling in your chest, shoulders, or back. Kneel on all fours, with your palms directly under your shoulders and your knees lined up with your hips. Arch your back upward and look at the floor near your feet so your back hunches, similar to the way a hissing cat looks. Stretch in this position for several seconds, then arch your back down as you look up to the ceiling, so your back has a cow-like sway to it. Hold this stretch for several seconds, then relax. Repeat the exercise about 3 times. Your sternum may crack when you move into the cow position. Lie on your back on an exercise mat or carpet, then bend your knees so your feet are flat on the floor. Push your hips up into the air, squeezing your ab muscles and your glutes as you lift. Hold the pose for a few seconds, then relax and lower yourself to the ground. Since your shoulders stay on the ground, this exercise can lengthen and stretch your sternum, which may cause it to crack. While stretching daily is a good idea, limit cracking your sternum to one time a day at the most. Just like with any other joint, cracking it too often can lead to hypermobility, which means the joint will extend past where it should naturally. This can lead to ongoing pain issues, and it can also make you more vulnerable to injury in that area.

summary: Push your elbows back for a simple stretch that might crack your sternum. Twist your torso side to side if your sternum hasn't cracked. Try a doorway stretch for an easy variation on a twist. Practice the cat-cow pose to crack your sternum with yoga. Try a bridge stretch to pop your sternum while you're lying down. Don't try to crack your sternum more than once a day.

For example, if you're shopping for new slacks, you'd want to grab a pair of slacks that fit you well. If you're shopping for jeans, you'd want to use a pair of jeans. Using similar pants is the best way to get an accurate inseam measurement. Sometimes pants will have the inseam measurement written right on the tag. If your pants do, you can use that measurement to shop for similar pants. If your pants don't, that's OK you can still measure the inseam yourself.

summary: Grab your best-fitting pants that are similar to what you're shopping for. Check the tag for an inseam measurement.

Guestbooks rely on script files in order to collect and display responses. Since you don't have the ability to upload scripts to Blogger blogs, you'll need to link to a guestbook that is hosted on another site. This will require you to create an account on this site so that you can manage and store your guestbook. There are free and paid options, depending on your needs. You'll be generating your guestbook on another website, and then copying the code for the book into a new page on your blog. There are a variety of different services available that can generate and host a guestbook. Different services will offer different features. A few of the most popular services are listed below, and most are free: Bravenet - Bravenet.com offers free guestbooks, and you can choose different designs and add smilies for guests to use.

It's actually a CAPTCHA service first and foremost that includes a guestbook among its features. Choose this option if the other features appeal to you as well, otherwise it's probably not worth it for just the guestbook. All of the services listed above require you to create an account. You'll use this account to manage your guestbook settings, since they can't be managed from your blog. This is because the actual guestbook database is located on the guestbook service's servers. You'll be prompted to enter your blog's address when creating your account. This will allow the service to connect to assign the guestbook to your website so that replies are properly tracked. Once you have created your account, you can begin customizing your guestbook. Depending on the service, you may have to open the guestbook's control panel.

Select "Get Code to Embed" and then copy the code from the box. If you selected 123Guestbook, you'll need to create a link to the guestbook's URL.
