How to Counteract Slouching and Open Up Stiff Shoulders and

In resting child's pose, hands outstretched in front of you, palms down, press your chest downward and alternate between leaning down into each armpit - think of making your armpits bigger with each pulse.

Next, starting on all fours, collapse one arm and thread it under your other arm until your head and leading arm are resting on the ground - you should feel a mild stretch through your downside shoulder region. Repeat on the other side.

Then, in the resting position of the previous stretch, actively lift your other arm to point straight up behind you. To accentuate this stretch, gently pulse the upward arm further backward. Repeat on the other side.

Next lying face down, rotate your body so that one foot ends up on the ground on the other side of your body while taking the same side arm up and behind you as far as it will comfortably go. In this position, maximally rotate your upside arm back and forth. Repeat on the other side.

To take the previous stretch a little deeper, repeat with a light weight in your upside hand.
