Sport, yes! But gently does it.
One month before the festive season, it's a good idea to start calmly preparing your body with regular gentle exercise, like walking. There's no point in throwing yourself into an intensive exercise programme:you risk injury and are likely to lose all your motivation after a few sessions. Try this 4-week walking programme to get back in shape. You'll feel great.
It doesn't matter whether you walk actively or even faster, don't worry:by keeping your foot in contact with the ground, walking reduces the impact on your joints. But that doesn't mean it's not an effective sport. The benefits for weight control and well-being make it the best exercise for your health, without forcing yourself!
