Start on the floor, with your hands set at about a shoulder-width distance, angling your hands in a way that feels comfortable. Extend your legs, with your feet also in a comfortable position, generally shoulder-width apart or wider for more stability. Be sure your body is in one straight line from your head to your heels; avoid having your butt or belly either sagging or sticking up. Clenching your butt cheeks and tightening your abs will ensure you’ve engaged your core. Keeping your gaze forward, slowly lower until your elbows form a 90-degree angle, keeping your arms in tight to your body. Then, push yourself back up, still keeping your elbows tight and your core engaged.
For additional support when first starting out, keep your knees bent on the floor and do modified push-ups. Either way, seven push-ups or more a day will help stimulate blood flow to your brain and generate new brain cells, which is the most effective weapon in fighting cognitive disease.
