http://umanitoba.fitdv.com/new/articles/article.html?artid=355 Pushups are a superb upper body exercise that use the body’s own weight to build a sound fitness foundation. They promote strength, balance and stability by developing several key muscles, including the pectoralis major in the chest, the deltoids or shoulder muscles, the scapular muscles and rotator cuff, the triceps located on the back of the upper arm and the upper back muscles.
“Pushups improve range of motion in the upper body and overall upper body strength. They’re important to a fitness regimen for developing general body strength, and core body strength. An important area of strength endurance can be developed through a higher number of repetitions,” says David Schuman, New Jersey-based speed and strength coach, former champion hurdler and owner of Schuman’s Speed Center (

Pushups can also contribute to better posture and help protect your back from injury and strain. According to Philadelphia-based author and back-pain specialist Dr. Jolie Bookspan, by practicing perfect form while executing pushups, and applying that same form to your upright stance, you may not only stand taller and straighter but you’ll reduce the potential for back pain."
I love pushups! I think that they are the fastest way to work your upper body if you are crunched for time or if you don't want to spend 40 minutes working each group individually. There are also many variations that you can do to emphasize different muscle groups. I did only ten minutes of pushups this morning and my shoulders, tris, chest, rear delts are fried. I also felt in in my bis because of retracting.
I LOVE PUSHUPS!!! IMO, they are the best upper body excercise!
