The muscle is divided into three heads - the lateral head, long head, and medial head. The closer together the hands are placed during a push-up, the harder the triceps work. The triceps also control the speed of elbow-joint flexion during the downward phase of the exercise. While the anterior deltoids and pectoralis major muscles work to horizontally adduct the upper arms during the upward phase of a push-up, the triceps brachii muscles, or triceps for short, are also hard at work extending the elbow joints so the arms can be fully extended. The medius and minimus sit under the largest butt muscle, the gluteus maximus. Two muscles called the gluteus medius and gluteus minimus stabilise the upper leg. The spinal runs adjacent to the spine, the longissimus runs adjacent to the spinal and the iliocostalis runs adjacent to the longissimus and over the ribs. Made up of three muscles including the spinal, longissimus, and iliocostalis. The erector spinae is the main stabiliser muscle in the back. The push-up depends on stabiliser muscles as the body is pushed and lowered. As a result, these muscles become very strong and can become defined as lean muscle after doing push-ups regularly. When pushing and lowering the body during a push-up, the pectoralis major is doing most of the work. These are the two large chest muscles and the main pushing muscle group of the upper body. The push up requires the work of many muscle groups, with one of the primary muscle groups being the chest muscles, the pectoralis major and the minor. Along with horizontal adduction, the anterior deltoid assists with flexion and internal rotation of the humerus within the shoulder socket. The deltoid attaches to parts of the clavicle and scapula, just above the shoulder joint on one end, and to the outside of the humerus bone on the other. It also helps control the speed of movement during the downward phase. The anterior portion of the deltoid muscle is one of the major shoulder-joint horizontal adductors, moving the upper arms toward the chest during the upward phase of a push-up. Both muscles compress the abdomen, and the rectus abdominis also flexes the spine forward, although it does not execute this function when performing push-ups. The transversus abdominis lies deep within the abdomen, wrapping around the entire abdominal area. The rectus abdominis spans the front of the abdomen and is the most prominent of the abdominal muscles. The rectus abdominis and transversus abdominis contract continually while performing push-ups to hold the body off the floor and keep the legs and torso aligned. Marine recruits at Marine Corps Recruit Depot San Diego perform push-ups in May 2005, as a part of their basic recruit training. Military recruits will often perform push-ups as part of their physical training. While the push-up primarily targets the muscles of the chest, arms, and shoulders, support required from other muscles results in a wider range of muscles integrated into the exercise.
In modified push-ups, where knees are used as the pivot point, subjects supported 53.56% and 61.80% of their body mass in up and down positions, respectively. Body mass supported during push-upsĪccording to the study published in Journal of Strength and Conditioning Research, the test subjects supported with their hands, on average, 69.16% of their body mass in the up position, and 75.04% in the down position during the traditional push-ups. I also found a great coach who was there everyday to help me stay on track! Today, I'm still working to sculpt my body and get it into the best shape ever.The American English term push-up was first used between 19, while the British press-up was first recorded between 19. At the same time, I re-found the online message boards at Beachbody where I meet a lot of great people who kept me committed to my fitness goals. I wanted to add some additional workouts to my run, so I pulled out my old Slim in 6 videos. I agreed, and this began my plan to get my body back in shape. She talked me into running weekly with her. In August 2007 my girlfriend wanted to get back in shape after her pregnancy. Since meeting him and our many days of eating out and less working out, my weight started to creep up. I got married to my wonderful husband in 2006. In my normal life, I am a civil engineer who sits behind a desk everyday.
