The most effective exercise to lower blood pressure

A study in the British Journal of Sports Medicine suggests isometric exercises like wall sitting (or wall squats) help reduce blood pressure more effectively than other forms of exercise - including weight training, high-intensity intervals (HIIT), and simple aerobic movements. Dr Jim Wiles is principal lecturer at Canterbury Christ Church University in the UK. He joins Jim on Sunday Morning to discuss the study and whether we should all be incorporating the wall sit into our routines.
