To be fit, you need to eat healthy food and exercise. If you have never exercised, you will have to start slowly by doing cardiovascular exercises in 30 minutes daily. Eat foods that can build your body through the training and others plus fruits to make you healthy. However, the whole thing needs patient meaning you will have to do it for a while before seeing good results.
Develop the right attitude. Incorporate more physical exercise into your daily routine. Start an exercise regimen and stick to it. Switch things up. Keep track of your progress and be proud of minor improvements. Give your body fuel.
