Look around your home for any swimming gear that you may have. Try on your swimsuit(s) and make sure it fits comfortably and allows you to move easily through the water without sliding off. See if you have other items such as ear plugs or goggles to make your swim more comfortable. Use or buy these for your swimming sessions if you like. Some accessories to consider include: Goggles A swim cap Ear plugs A nose plug Aquatic shoes Have a professional give you a refresher on how to perform different strokes. Take a swimming class with an instructor if you don't know how to swim or feel uncomfortable in the water. Taking private or class swimming lessons can ensure you use proper swimming form and gain optimal cardio and strength results. Look for classes at a local recreational center, pool, or health club. Ask your swim instructor to teach several different strokes using proper techniques. Build up your swimming fitness by starting with 15-30 minutes of swimming 3 to 5 days a week at an easy to moderate stroke speed for you. Gradually increase your overall time and stroke speed as you get stronger and have better endurance. Giving yourself time to build up water fitness can minimize your risk of injury or overdoing it. Perform light moves like arm, wrist, and ankle circles, leg lifts, calf raises, and donkey kicks either before or after you've slipped into the water. Then, warm up by swimming at a slow pace for about 10 more minutes. Warming up gives your body a chance to get used to movement and can minimize your risk of injury. Some different examples of how to mix up a warm up include: 4 laps swimming, 2 laps kicking, 1 lap pulling, 1 lap swimming. You'll need a kickboard for kicking laps (i.e. just using your lower body) and a "pull buoy" for pulling laps (i.e. just using your upper body). 20 lap swim, or any distance of your choice 10-15 minutes of anything you feel like doing in the pool After your warm up, start your main set, which will really train your cardiovascular system and muscles. Once a week, include speed sets and drills. Try any of the following as a part of your speed workout: Swim 4 laps, rest, and then repeat 3 more times Swim 1 lap at maximum effort, rest for 30 seconds and repeat 9 more times Swim 8 laps with decreasing stroke speed, swim 4 laps at your easy pace, and repeat one more time Focus one of your swim workouts on building endurance. This can help develop your muscles and cardiovascular system. It may also improve your speed. Consider any of the following endurance sets or create one yourself: Swim 4 laps at a moderate pace, rest 20 seconds, and repeat 3 more times Swim 6 laps at a moderate pace focusing on proper technique, rest for 2 minutes, and repeat one more time Swim 10 laps at an easy to moderate pace, rest for 2 minutes, and repeat three more times Focus one additional day on developing your technique and strength. Swim with props such as pull buoys or kickboards. Drills help develop your stroke technique and build muscle. They can even improve your speed and endurance. Try the following technique workouts: Use a pull-buoy for 4 laps, rest for one minute and repeat one more time Swim 4 laps with one arm and then repeat on the other arm Swim 4 laps breathing on one side of your body, rest, swim 4 laps breathing on the other side, rest, and then swim 4 laps alternating breaths on each side of your body Mix up your workouts by doing different strokes for each lap or every few laps. Incorporating these different body movements works different muscle groups, increases your endurance and helps you get a better feel for the water. Use any of the following strokes during your warm up, main set, and cool down: Backstroke Breaststroke Freestyle Butterfly Side stroke Try out different gadgets that your local pool has available to anyone to enhance your training. Using training aids such as pull buoys or flippers can build targeted strength and improve stroke technique. The different types of training aids you can use while swimming include: Kickboards Flippers Pull buoys Resistance gloves Hand paddles Swim for a few minutes or laps after you've finished your main set. Cooling down and gradually slowing the heart rate can help prevent blood from pooling in any one part of the body. This may help improve how your muscles feel after exercise. Remember to do as many laps as you are able to start, adding more as you get stronger.

Article: Use a sharp chef's knife or serrated knife. Cut an X shape into the flat side, or belly, of the chestnuts. Cut as deeply as you can without cutting the chestnut into pieces. Wear rubber or leather gloves while you cut to avoid cutting yourself because chestnuts can be slippery. Put the chestnuts in single layer in a glass baking dish. It doesn't matter if the chestnuts are touching, but they should not be on top of each other. Cover the dish with a layer of waxed paper. Put the glass dish covered with wax paper into the microwave. The chestnuts are ready when the shells start to pull back. You can microwave the chestnuts for a minute more if the shells haven't pulled back after 6 minutes. Allow the chestnuts to cool for a minute because they may be very hot after removing them from the microwave. Use a small, but sharp knife to peel off shells and as much of the inner brown skins as possible. This may take some effort, so work slowly and carefully in order to avoid injury.
