Upper body exercise that targets chest, shoulders, biceps, triceps and core. Place hands under shoulders with the angle of the fingers pointed inward about 45 degrees or less. From a plank either on the knees or toes, engage around your shoulder blades by pushing the floor away and engage core. Inhale, draw the shoulder blades together allowing the chest to lower towards the floor. Exhale as you push into the ground, sliding the shoulder blades apart. Push back into a down dog or rest pose to reset after each rep. Watch the head placement as you lower down, keep the head back in line with the shoulders by looking slightly forward. Watch core engagement on press away from floor so the hips do not drop forward. Modify this movement by starting on incline such as a wall or counter and work your way down to the ground. You can also do this quadruped.
