Push-ups are one of the best, if not the best workout you could get for your chest without a gym pass. It also tones abs, triceps, torso & shoulders. I know, you probably hated them as much as I did back in high school! I managed to get over that attitude & did them myself to see what i could get from them....I do about a hundred a day & I feel way more energy after the workout. The best part is they can be done anywhere! In your office, home, during tv commercials Also, body weight exercise manages to burn fat & raise metabolism. No reason why push-ups shouldn't be added to your daily regime. If your still thinking, stop & do them! Results in about a week!
