You can strengthen your core without moving a muscle
Whereas most muscles propel you, your core resists movement – for instance, to protect your spine when you twist your torso. So don’t be surprised by how hard it is to stay still during a core workout. You’re conditioning your core to do its job more effectively.
Slouching sabotages your six-pack
Training your core helps correct poor posture. But an hour a week of core work can’t compensate for the 50 hours spent slumped over your keyboard. The fix: stay tall through your hips and keep your head up and shoulders back and down all day long.
Core muscles contract first in every exercise
All the energy you exert originates in your torso, before being transferred to your arms and legs. So a weak core reduces the amount of force you’re able to apply to a barbell. When you hit a plateau in presses, squats or any other strength move, ask yourself if you’re training your core as hard as you can.
