Your back should be straight, and your head should be lifted comfortably so that you're looking straight ahead at the conductor, if there is one, or straight ahead if you're playing alone. Your back should not be touching the back of the chair, your feet flat on the floor. Depending on your height, it may be appropriate to rest the tuba on the chair between your legs or rest it on your lap, gently on the top of your thighs. If it's a full-size tuba, you may want to get a stand to set it on. It's important to position the tuba in such a way that you will not have to bend yourself to reach the mouthpiece. Bring the horn to you, don't bend to the horn. When you try to fill the horn with air, you'll notice a big difference. On a right-handed tuba, you'll lean the tuba slightly to the left, using your left hand to support the lean. Place your right hand on the valves, either on the broad part of the pad on a rotary tuba, or with your fingertips on the center of the valves on a valve tuba. Most tubas have a small ring to put your thumb through. This forces your hand to stay in place and helps give a bit of support from your right hand. Find the ring, if your tuba has one, and position your hand accordingly. On a lefty tuba, you'll be resting the tuba practically on your left leg which is why stands are very important for lefty players. Your right hand has to reach for the valves, but it will also be providing a lot of support. The left hand will keep things balanced. Although it may be tempting, do not curl your right thumb. That causes your fingers to be under your valves with only the tips on top. Hold your fingers upwards on top of the valves so that they go straight up and straight down when pressed. Let your lap support the tuba, not your arms. Try to relax your shoulders and let your arms hold the tuba loosely. Treat it like your date, not like your wrestling partner. The more comfortably you can move around the horn, the better you'll be able to play.

One-sentence summary -- Sit on the edge of your seat and be relaxed. Rest the tuba on your lap. Use the correct hand positioning. Relax your shoulders.

Q: Your training plan should include ways that the trainers can evaluate the training as it progresses. There should be clear benchmarks that measure the effectiveness of the training. Specifically state the points during training where the goals should be measured. Have concrete assessment tools included in your training plan. For example, you could have trainees complete a quiz or test after each module. Have trainers ask for feedback. In your training plan, indicate that trainers should observe the trainees attitudes. If the trainees seem lost or unmotivated, indicate that that trainers should address that. Not every group of trainees will respond the same to your training methods. You training plan should indicate that trainers will need to be prepared to teach the material in a different way. For each section of content, your training plan should indicate a couple of different ways to convey the material. For example, some groups may be less talkative than others. Instead of a large group question and answer session, have the the trainees work in pairs. In your delivery of the material, you will likely use specific examples to illustrate your points. If the trainees do not seem to comprehend the material, make sure that there are alternate examples included in the training plan. Your training may be organization-wide, geared toward a single department or designed specifically for entry-level employees. You may develop separate training plans for different groups or teams. In each plan, be clear about the group that is the focus of the training. Group the trainees by training type. For example, some members of the organization may need simple overviews, whereas others involved in the day-to-day completion of tasks may require in-depth training. For example, you will need to calculate training costs. If you are not involved with accounting, you may need to ask someone familiar with your company's financials for some information. Review the list of required training resources to determine how much money you will need. Other costs to consider include meeting space rental, trainer compensation and employee time. You may also need to speak to your organization's facilities manager. They can help you reserve conference rooms or lecture facilities. Let your IT department know that you might need some assistance during training, particularly if you are teaching online or using tools such as video conferencing. In order to offer the most effective training, you will need to select the highest quality employee to conduct the training sessions. They may be people already working for the organization or outside experts. Examine their qualifications and experience before hiring. Look for trainers who have experience using the methods that you want to offer. For example, if your training is to be conducted online, make sure to find someone who feels comfortable using that platform. Communicate with your trainers. Allow them the opportunity to ask questions and make sure that they clearly understand the objectives and desired outcomes.
A: Assess the training. Offer alternatives. Indicate the training participants. Utilize your colleagues. Choose qualified trainers.

Article: This is often a good thing, and for people with very large hands, it is a must to allow for a solid fit on the grip. The grips have problems though. They can occasionally move, and this can affect accuracy and require constant adjustment. Most tactical-style handguns have groves and hatches in the grip to allow a firm grip even with sweaty palms; and sometimes, the rubber makes the gun a bit slippery when wet. Additional maintenance is also required, as sweat and dirt will build up under the grip, which then requires the rubber to be taken off and the gun's grip and rubber cleaned thoroughly. With large hands, or for a gun which has a very uncomfortable grip, try using rubber grips.
Question: What is a summary of what this article is about?
Rubber slip-on grips can make a sidearm more comfortable.

Article: Not having a car can save you money, but other commute costs can add up to. Do you buy a monthly train pass, maintain your bike, or split gas for an office carpool? Set aside that amount of money each month. If you walk or bike to work, you can also set aside a taxi budget. This will come in handy if the weather is too wild to travel in. A careless commute can take longer than average; make sure you're giving yourself enough time to complete it. Set several alarms if you have to. Streamlining your morning routine in general can help with time. Make your lunch the night before, take a short shower, and don't get distracted by TV during breakfast. If you're not in the cozy embrace of a car, extreme weather can wreak havoc on your commute. Make sure you read the weather report before you leave the house each morning, and take precautions if you need to. Dress sensibly in layers, and wear sturdy boots or shoes if needed. Carry an umbrella. Keep a small folding umbrella in your briefcase or backpack, so your day won't be too derailed by a sudden downpour. Use oil-blotting sheets or a cooling face mist to defeat sweat and look put-together at work if you bike or walk in the heat. Take a taxi if it's too much to bear. Don't panic if your train is stalled or your tire pops. Emergencies happen to everyone, whether they drive to work. Let your boss know about the situation as soon as possible, and update them if anything changes. Always leave home with your phone charged in case of emergency. You should have your boss's number saved, too.
Question: What is a summary of what this article is about?
Budget for your commute costs. Don't oversleep. Check the weather. Let your boss know if you'll be late.
