While the close-grip pushup primarily works the tricep, that’s certainly not all it does. Complete Fitness personal trainer, Travis Hackett says he likes this move because it “also focuses on other muscle groups. making it more challenging while burning more calories.” Lie face down on the floor with hands palm down, fingers pointing straight ahead. Place your hands in the center of your chest and form a diamond shape with your index fingers and thumbs. Feet should be at hip width with toes on floor. Extend the elbows and raise the body off the floor. Lower your entire body (legs, hips, trunk, and head) 4-8 inches from the floor. Return to the start position by extending at the elbows and pushing the body up.  Remember to keep the head and trunk stabilized in a neutral position by isometrically contracting the abdominal and back muscles. Never fully lock out the elbows at the start position and avoid hyperextension of the low back.
