When performing push-ups properly, you mainly train the muscle groups in the upper body such as the chest, shoulders and tripods. In addition, this move also helps activate the abdominal and hip muscles.
A common cause of lower back pain when doing push-ups is due to poor posture, especially when you let your hamstrings down while doing push-ups. This increases pressure on the spine and can lead to back pain.
To avoid side stiffness when dozing, tighten your abs and quadriceps throughout the procedure.
How to do push-ups properly
Start with your hands and knees, place your hands directly under your shoulders, knees under your hips. Stretch your legs back, supported with your toes, your body forms a straight line from head to heels.
Place your hands in a line under your shoulders or slightly wider. Bend your elbows about 45 degrees from your torso, lowering your body close to the floor. Keep your back, hips and legs in line as you lower them.
Use the force in your palms to push yourself back into a high plank position, keeping your body in a straight line.
Note, always tighten your abs, keep your hips still, and control your breathing throughout the exercise to achieve the best results and avoid injury.
