How to be a boxer
Sign up for classes at a local boxing gym.
Look online for boxing gyms in your area and find one near you. Once you find a location that you can travel to regularly, visit them or call them on the phone to see what times they offer classes and how much they cost.
Many gyms offer a per-session rate as low as $10-$50, so you can try out the gym before committing to a monthly plan. Go to the gym before committing to classes to see how comfortable you feel with the trainers there.
