Assume the correct posture at all times when using the bike to prevent injuries due to poor form. Ensure that you are properly balanced on the bike at all times to minimize the possibility of falling off. If the soft cover parts of the bike - particularly the seat and handlebars - are worn out, they can cause you or your hands to slip out, leading to injury; replace them. Regular spinning can cause muscle fatigue. Take breaks so that you're not riding every day. This will give your muscles time to recover. If you have any underlying health condition, talk to your doctor to find out whether it's safe for you to use the spin bike.
