You can practice the tight rope at home to improve your balance.
For this one you can use a string or any straight line you have on the ground in your home. With your hands out to your sides shoulder height and your palms up imagine you are walking along a tight rope. Try to look straight ahead the entire time. Walk all the way forward and all the way back with the seam or line in the middle of your foot. When that is easy for you, try walking backwards. Go back and forth 5 times.
