(PART 2 of 2) If you are doing aerobic exercise such as running, try to keep well hydrated. Keep water with you during your exercise if you can, and drink small amounts regularly. Don't wait until you are thirsty to drink, do it throughout the exercise, but only small amounts at a time. There's nothing worse than running when you can hear and feel pints of water sloshing about in your stomach. Don't push yourself to exhaustion. You should feel slightly out of breath during the exercise but should be able to conduct a conversation with somebody at the same time, so not so breathless that you can't speak. If you are training for a specific event, you will be able to push yourself harder over time. It may be a good idea to have a routine check-up with your GP before you start a regular exercise programme, to check that your heart beat and blood pressure are normal. Finally, well done for making the decision to pursue a healthier life, your body will thank you and reward you for it in the long run, and you should start to feel the benefits pretty quickly. Good luck.
