First, breathe every time you do an action. Breathing is done during the action. For example, exhale when using force, inhale when reducing weight or inhale when using force, and exhale when reducing weight. However, under normal circumstances, when the load is heavy, when doing exercises on your back or doing chest and abdomen exercises, the former breathing method is adopted, that is, when the muscles contract, hold your breath instantly, exhale quickly, and inhale slowly when the muscles stretch. However, we should adopt the latter method when practicing light load and concession, that is, inhale quickly when muscles contract and exhale slowly when muscles stretch. Inhale quickly and forcefully and exhale slowly and deeply.
Second, several movements, one action, one breath or several breaths. When we first started training, just like preparing for warm-up exercises, we often used the former breathing method, which is to pause and take a breath after doing several actions in a row. After a few more moves, breathe again. When we want to break through our exercise limits, do heavy exercise or get tired, we can use the latter breathing method, that is, breathe several times at a time.
Third, breathe naturally. Keep a natural and unconscious breathing rhythm during fitness. Natural breathing is mostly used for lightweight and slow-motion exercises.
Fourth, breathe forward. Breathe in when muscles contract hard, and exhale when stretching resumes. This is the most commonly used breathing method for fitness, and it is also recognized by most fitness enthusiasts.
