Best Move for Your Chest and Upper Back: The Modified Push-up
Why it works: The basic stance, coupled with changing hand positions, targets all the muscles in the area.
How to do it:
1. Start with arms straight, knees on the ground, back in a plank position, and palms placed slightly closer than shoulder-width apart. Keep your abdominals tight and your neck relaxed.
2. Bend your elbows and lower your torso toward the ground for a count of two, keeping your elbows close to your body (they should point behind you, not out to the sides). Straighten to the starting position for two counts. Do eight reps.
