You don’t need a yoga class to undo eight hours at a desk. A few minutes spread across the day does most of the work.

Open the chest

Clasp your hands behind your back and gently lift them away from your spine. Hold for five breaths.

Loosen the hips

Stand up, step one foot back and sink into a light lunge. Switch sides after thirty seconds.

Peridot reminds you to stand up and stretch when you’ve been still for too long.
