Running and lifting
Every week I make sure to work out for at least an hour and you should to. There is no magic pill that makes up for lack of exercise. I always make sure to run at least a mile a week around my neighborhood and to lift some weight on the bench press and finish off with some arm curls and sit ups. I know that i could do a lot more to gain muscle mass and some weight but that is not what I am wanting my physic to look like, so I eat right and stay active with my sports and make sure to work out hard at least once a week.
I always hear commercials on the radio television or just about anywhere diet places can advertise, and to me this is not the solution. A quick diet does nothing for your health overall, such as stamina and endurance, so staying active is something that needs to be done. Otherwise you could end up with bad long term health issues.
