Balance is one of those things that is good for just about everything including a balanced diet, stress management, and it is also a great physical exercise. There’s nothing you do that won’t improve with good balance. Balance is also the main reason trainers prefer to use free weights over machines. When you use free weights or pick up rocks, tires, medicine balls, etc. they challenge support muscles throughout your body, which strengthen the functional muscles you need to thrive in everyday life.
When you strengthen muscles related to balance and structure you are able to exert more force with less energy. Essentially, you can exert force equal to the amount you can withstand without losing your balance which is why isolated machines are not preferred, the machines will absorb the force your body should be adjusting to. This is also why play is so important, you need to have good balance to maneuver yourself and quickly adapt to real-time changes in the game. Through play, balance incrementally increases over time. There are some great exercises you can do to develop balance.
