This is a standard push-up performed with your hands close together under the
chest.
Try to keep your back straight and your arms about shoulder-width apart. Make sure
your back doesn't hunch or sag down.
While focusing on your triceps, slowly lower your body by bending your arms at the
elbows. Lower until you are within an inch of the floor. Focus on the stretch.
Hold for 1-2 seconds, then push back up to the starting position.
Tips
If you find it to difficult to complete the required reps, place your knees on the
ground - this will make you use less bodyweight for the exercise.
