You might have seen people online or friends doing stunts with pogo sticks. Only do what you are comfortable doing and don't do anything you are not ready to try. Make sure you can do regular jumping with ease before you attempt any tricks. Once you have control of your pogo stick, you can try jumping with one foot. Start jumping how you normally would. When you have a good rhythm going, take the foot off the pogo stick that is not dominate. (If you are right footed, take off your left foot). Lean to the side of the pogo stick that does not have a foot on it to try to center yourself perfectly. To jump without any hands, start jumping how you would normally jump. Then, use your knees to get a good grip on the pogo stick. Slowly take your hands off of the pogo stick handles. Make sure to continue to jump, securing the pogo stick with your knees and using your knees to pull the pogo stick up. Once you start jumping with no hands have somebody give you a ball. You can use a basketball and shoot it in a basket while you are on the pogo stick.

summary: Don't do anything you aren't ready to do. Jump with one foot. Jump with no hands.

Depending on your reasons for trying to deepen your voice, you might decide that it's worth pursuing options that cost money. Voice training and surgery are two of these options, both with large potential for success. If you want a lower voice to improve your confidence or social or dating life, you may want to stick to the slower but safer and cheaper options. One surgery shown to reduce the pitch of one's speaking voice permanently is called a thyroplasty and it involves reducing the tension in the vocal chords. Another involves injecting a subjects own fat into their vocal folds, which can reportedly lower pitches and improve voice quality. Though hormone replacement therapy alone usually lowers trans men's voices to more masculine levels, surgeries like these can be a next step for those that desire deeper voices. Vocologists specialize in helping their clients improve their speech in any number of ways, including altering their pitch. A good vocologist will help you identify the causes of your high-pitched voice and teach you change them. There are even vocologists who specialize in helping transgender people achieve more masculine or feminine voices. Your chances of lowering your pitch permanently are increased greatly if you get the help from a professional rather than just relying on self-guided practice.
summary: Decide whether more costly options are right for you. Look into voice lowering surgery. Get voice training from a speech expert.
