Exercise is guaranteed to boost your energy levels, whatever your mood.

Research shows that just a brief workout can provide you with an instant pick-me-up when your mood is low.

It works on a cellular level: exercise fires up your mitrochondria – the energy-producing component of your cells – and sends oxygen around your body to meet the demands of your activity, keeping you on a high even after your workout.

Include a workout into your routine to leave you feeling more fresh and ready for the day.
