In one sentence, describe what the following article is about: Certain medications and conditions can make it hard to gain weight. If this is the case, make sure you’re treating your medical condition. Talk to your doctor to find the right options for you. If you have lost a significant amount of weight without explanation, see your doctor to make sure that you do not have an underlying condition, such as a thyroid or digestive disorder. A registered dietitian can help you design meal plans to help you reach your weight goals in a healthy manner. They can also provide advice about exercising or stimulating your appetite. Ask your doctor to refer you to a registered dietitian. Smoking suppresses your appetite and can affect your sense of taste and smell. Talk to your doctor to discuss strategies for quitting smoking. Your doctor may be able to prescribe a path or pill to help you quit. If you cannot quit smoking, try to avoid smoking for an hour or 2 before you eat a meal. While not the fastest option, strength training is a good idea if you want to keep weight on long-term. Exercise is a good way to whet your appetite. Strength training, in particular, is especially good because it allows you to gain weight by building your muscles.   Weight training is a great place to start. You can also do body weight exercises like yoga or Pilates. Avoid too much cardio or aerobic exercise, as they may prevent you from gaining weight. Eating extra protein is especially important if you plan to build muscle mass through exercise. Good strength training exercises include squats, deadlifts, overhead presses, bench presses, barbell rows, dips, chin-ups, crunches, bicep curls, leg presses, and leg curls.
Summary: Treat any underlying medical conditions. Talk to a registered dietitian. Quit smoking. Start strength training to build muscle.

In one sentence, describe what the following article is about: This will make the shuttle spin and fall in an unpredictable direction. To slice your net shot, start the forward motion as you normally would, and then move the racket inward as you slice the racket perpendicular to the center of the birdie. Your opponent will be expecting you to hit the birdie directly forward, while it will actually spin cross court. To do this, slice the racket, or move it perpendicularly over the center of the shuttle when it's in the air. This will make the shuttle lose much of its momentum and quickly fall on the opponent's side near the net. Smashing is when you hit the shuttle with all of your strength at the top of its arc. Point your free hand at the shuttle to keep track of its path, and then swing the racket over your head, hitting the center of the birdie and smashing it down into the opponent's court. This is similar to serving in tennis. When you're smashing the shuttle, aim is just as important as strength. Don't just blindly hit the shuttle as hard as you can -- you should try to aim it either as far away from your opponent as possible or right at your opponent's body so he will be caught off guard. Once you've mastered the standard smash, you can practice jumping up as you smash the shuttle. This will give you even more momentum and will make the shuttle fall into your opponent's court even faster. Just jump up a foot or two, aiming your chest and body in the direction that you want the shuttle to go, and smash it at the center of its arc. The smash should be used at a time when the shuttle is high in the air and you have plenty of time to approach -- it should end the point in your favor. If you smash the shuttle at every opportunity, you will tire your arms and will risk smashing it into the net at inopportune moments. A beginning player is just happy when he hits the shuttle over the net. An advanced player understands that a good game of badminton is like a game of chess -- you should always position your shot wisely so that you move your opponent to the exact place where you want him to be so you can hit the following shot. Always plan your next move and always think one step ahead of your opponent.
Summary:
Slice your net shots. Slice your drop shots. Smash the shuttle. Jump before you smash the shuttle. Don't smash the shuttle every time. Always plan your next move.
