You MUST consult your doctor before you begin this, or any exercise programme if you have a medical condition that may affect your ability to exercise.
You should be aware that taking part in ANY physical activity will affect heart rate, blood pressure and breathing responses, and in most cases this will be a normal thing.
If you feel dizzy, nauseous, light headed, faint, then you must stop immediately and inform the instructor.
Every participant must complete a PAR Q medical form which will highlight any contra-indications to exercise. If you are asthmatic, you must carry your inhaler.
