Walking for 20-40 minutes per day has huge health benefits. It has been proven to reduce the risk of diseases such as heart disease, dementia, diabetes, cancer and depression. If done correctly it also reduces injury risk as it engages the gluteal muscles which are the primary muscle for propelling us forward. However if you sit for more than 6 hours the gluteal muscles ‘switch off’. With regard to walking correctly it needs to be done at a brisk pace and with a full arm swing.[Very few of us use a full arm swing] Try it for a week and see how you feel!
