Working from home has been hard for our backs! Long working hours mean that working from the couch (or the bed!) are too tempting some days. Although both these spots seem to be a small luxury, they are not a treat for our backs and shoulders. They are never supportive enough for us to sit and work for an extended period of time so we inevitably start to round our shoulders to mirror the tuck in our pelvis as we leisurely sit back.
Over time this makes the muscles that give us good posture longer, weaker and less active. Yoga will not counteract hours sat like this but it will help you rebalance if you also make some lifestyle changes and set up a more back-friendly working environment!
