1: you have more energy, having more energy is good because you can get stuff done because you now have the energy to do it
2:you feel better. If your out of shape and your getting in shape you will start to feel a lot better waking up and you will sleep better
3:more confident. Getting in shape means your body will change in good ways and you will look better in the mirror and to other people and be more confident in yourself
