Always maintain a correct breathing pattern while performing resistance activities. Immediately prior to lifting a weight, inhale deeply. Hold the air in the lungs and gradually exhale as you perform the weight movement. Relax, then inhale deeply again as you repeat the process. Never hold your breath while you are performing resistance exercises!
Inhale deeply from your abdominal area while contracting your abs.
Hold it for a few seconds and gradually exhale through your mouth.
