Breathing deeply while you’re running is important because it fills your lungs with more oxygen, which then gives your body more energy to keep running. If you’re only taking shallow chest breaths when you run, try to practice breathing from your diaphragm so your belly expands when you inhale. If taking steady, deep breaths is hard for you to do while you're running, try experimenting with different breathing rhythms until you find one that's comfortable. For example, you could inhale deeply once and then exhale out of your mouth twice. It’s easy to hold your breath when you’re doing core and abdominal exercises, but doing so can become a crutch, and it actually makes your workout harder on your muscles. Instead, as you do your exercises, try to maintain a steady 4 count as you inhale and then another 4 count as you exhale. That way, you’ll breathe consistently as you work out your core. High-intensity exercises, like jumping jacks and burpees, require a lot of oxygen, but taking in a lot of air through your mouth can actually reduce your body’s ability to use the oxygen as energy. Instead, inhale through your nose during these exercises so you’re getting more oxygen into your body, which will help you work out for longer. Breathing properly during strength-training exercises can improve your form and help prevent complications, like hernias. Instead of breathing erratically when you lift weights or do other strength exercises, try to exhale when you’re lifting and inhale when you’re lowering.  For example, when you’re doing bicep curls, you would exhale as you lift the weight up, and then inhale as you lower it back down. If you’re having trouble breathing like this, you might be lifting too much or overexerting yourself. If you do have difficulty breathing then contact your nearest doctor, or if worse an emergency ambulance.
