Problem: Article: Glycerin is often sold in supermarkets, craft stores, and beauty stores in a 2 lb (0.91 kg) block. Once you have the 1 lb (0.45 kg) block of glycerin you need for this recipe, you can save the other half for another saddle soap mixture in the future. If you're storing extra glycerin for future use, you can wrap it in plastic wrap or wax paper, and store it in a cool, dry area. The small chunks of glycerin you cut do not have to be perfect or even. Cut the block into small chunks the size of your thumbnail. These smaller pieces will melt more quickly in your microwave. Place the small chunks of glycerin in a microwaveable bowl. Heat the glycerin on medium power for 30 seconds in your microwave, then remove and stir. Keep microwaving in 30 second intervals until the glycerin has melted. A 1 lb (0.45 kg) piece of glycerin will make approximately 2 cups (470 mL) of liquid when melted. Stir continuously to combine. To make a scented version of saddle soap, replace the milk or cream with 0.25 cups (59 mL) leather cleaner (not leather conditioner). Stir in a few drops of scented essential oils. Cream-based saddle soap made with animal fats and protein, like milk, condition leather well. Make sure you scrape any buildup from the sides and mix it in as well. It will begin to thicken as it cools. Once your soap mixture is becoming harder to stir but still able to be poured, it’s ready for storage. Let your saddle soap cool for an hour or two before sealing the jar or container. When it is hard to the touch, it has set and is ready to use. The glycerin will prevent the milk or cream in your soap from going rancid. Make your saddle soap last longer by storing it away from water in a cool, dry place.
Summary: Cut a 2 lb (0.91 kg) block of glycerin in half. Cut the 1 lb (0.45 kg) block of glycerin into smaller chunks. Melt the 1 lb (0.45 kg) of glycerin in 30 second intervals. Stir the 0.25 cups (59 mL) of milk or cream into your mixture. Stir your soap mixture until it begins to thicken. Pour the mixture into your jar or container.

In one sentence, describe what the following article is about: Some exercises that require weights can be done without weights. If you don't have time to hit the gym, you can do calisthenics almost anywhere.  To do an air squat, set up as if you were in front of the squat rack at the gym. Put your feet a little more than shoulder width apart, with your toes facing outward. Using the same form you would in weighted squats, lower your hips and push your butt back. To help keep your balance, push your arms out in front of you as you lower down.  Lunges can be performed without weights very easily. The form is exactly the same with or without weights. To do a glute kickback, set up as if you were going to do a push-up, but stay on your knees. Lift one leg off the ground until your thigh is parallel to the ground. Keep your shin perpendicular to the ground and push your leg up. Lower you leg slowly and repeat with the other leg. To do a short bridge, lie flat on your back with the bottoms of your feet on the floor and your knees at about 45 degrees. Keep your shoulders and arms on the floor. Push up using your heels and raise your hips up as high as possible. Hold at the top for two seconds. Slowly lower your body back to the ground.  Once you've mastered the short bridge, try doing a straight bridge. The straight bridge is a lot like a reverse push up. Sitting up with your legs straight in front of you, place your hands near your hips. Push your torso up and squeeze your butt. Hold for a few seconds before lowering back down.  To do a full bridge, lie flat on your back. Bend your knees and place your hands by your head. Lift your entire body off the ground and arch your back. Push your hips into the air and squeeze your legs, butt, and core. Take a deep breath and make sure you give everything a good stretch. Hold for a 1-2 seconds and then lower yourself back down. Lie down on your side and rest your head on your bottom arm. Place your other arm palm down in front of you body. Keep both of your legs straight and lift your top leg about 1 foot off of your bottom leg. Lift your bottom leg to meet your top leg. Slowly lower both legs to the ground. Another variation is to lie flat on your back with your legs straight in front of you. Slowly lift your legs off the ground to a 90-degree angle. Hold for one second and then lower your legs taking care not to let them touch the ground. Running is a great way to tone your legs and butt. Any kind of running is likely to improve your lower body, but sprinting might be the best way.  For an added challenge, run up a hill. Hill sprints will improve your glutes by putting more stress on your hip flexors.  Running is a high impact activity and may not be good for your joints. If you can't run, try using an elliptical machine or a stationary bike. There are numerous exercises that workout your glutes and lower body. Do some research and find some new exercises to incorporate into your routine. Some people find that adding new exercises keeps them motivated to keep working out.  Try out a hip thrust exercise for something a little different. You could also try joining a yoga class. Yoga is an excellent way to strengthen your muscles, increase flexibility, and tone your body.
Summary:
Add calisthenics to your routine. Try doing bridges. Do leg raises. Go for a run. Experiment with other exercises.
