The good-morning is a weight training exercise. It is known as a good morning because of the movement in the erector spinae which resembles the bow that traditionally begins a schoolday in some East-Asian countries. The erector spinae muscles of the lower back work isometrically to keep the spine in an extended position while the hamstrings and gluteus maximus work isotonically to perform hip extension. Other muscles are involved in stabilizing weight on the back and maintaining balance.
The degree of knee bend used will change the focus. The straighter the knees, the more the hamstrings are stretched and stressed by the movement and this stretch involves them more as the hip extensors. Bent knees can shift the weight forward, which allows the pelvis to drift back further as the body hinges in hip flexion.
The good-morning is an essential exercise in the Westside Barbell method and is often trained to near limit maxima. Developing strength in the lift aids in the recovery of a "bad" squat, reducing the risk of injury. Properly applied, it can also strengthen an individual's deadlift; for this reason, it is a key exercise in the conjugate method of training this lift.
In Olympic weightlifting, the good-morning is used as the most efficient assistance exercise to train the second phase of the clean or snatch pull and bases of squat positions in snatch drops and clean squat positions. In this variation, the lifter will descend, reverse direction, and accelerate the ascent, rising up onto the toes at the conclusion of the lift. This mimics the rapid hip extension and subsequent toe-rise during the clean and jerk or snatch.
One starts with a barbell held on one's shoulders, behind the head. Similar to a back squat, there is some variation with the height on the back at which the bar is held. Holding the bar lower on the back decreases the distance to the pelvis and decreases the strain on the hip and spine extensors: a low bar position allows one to lift heavier weights while a high position allows one to stress the muscles harder with a lighter weight.
Another possibility is to hold a barbell at the crooks of the arms, on the inside of the elbow, as in a Zercher squat .
The lifter bends forward, bowing at the hips while keeping the back straight. This is the eccentric portion. The motion is at its halfway point when the lifter's torso is almost parallel with the ground, after which the lifter returns to the upright position, during the concentric portion.
It is recommended that the lifter avoid rounding (flexing) or rotation (twisting) at any point during movement; however, it appears that some spinal flexion is elicited during the movement. [1] [2] [3] A properly distributed bar, balance and core stability help to prevent this from occurring in excess. The lifter should rather concentrate on pushing the hips back while keeping the spine straight or arched.
Other forms of resistance can be used other than a barbell in variations of the movement. While awkward and creating pressure points, dumbbells or kettlebells may be used. A sandbag is a comfortable alternative, or a medicine ball held behind the head. Weighted clubs or maces can be set against the back. Stretch bands anchored under the feet are also used.
The movement can also be performed with an empty bar, a broomstick, or one's body weight, a variation suitable for beginners, casual stretching, warmups, warmdowns or endurance training.
A similar exercise and easier alternative for odd implements such as dumbbells would be doing stiff or straight legged deadlifts. This involves the arms hanging down rather than up at one's back, and the pressure is exerted on the back through being held in the hands and through one's supporting back musculature such as the lattismus dorsi, trapezius and rhomboids.
The good-morning is a controversial exercise as some will claim that it leads to lower back injuries. Famously, Bruce Lee seriously injured himself while performing the exercise after an inadequate warm-up and over confidently selecting his working weight. On the other hand, the good-morning can also strengthen the lower back and prevent injury when properly applied.
Rounding the back can result in back injuries. To aid in preventing a rounded back, the lifter's chin should remain upright. A common technique is to focus the eyes on a spot at about belt height during the lift, reversing direction after lowering when the eyes come in line with the spot. At the bottom of the range of motion, this keeps the chin up and the head tilted back, facilitating a flat or slightly arched spine.
Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: squat, bench press, and deadlift. As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single-lift effort of a barbell loaded with weight plates. Powerlifting evolved from a sport known as "odd lifts", which followed the same three-attempt format but used a wider variety of events, akin to strongman competition. Eventually, odd lifts became standardized to the current three.
The clean and jerk is a composite of two weightlifting movements, most often performed with a barbell: the clean and the jerk. During the clean, the lifter moves the barbell from the floor to a racked position across the deltoids, without resting fully on the clavicles. During the jerk, the lifter raises the barbell to a stationary position above the head, finishing with straight arms and legs, and the feet in the same plane as the torso and barbell.
The bench press, or chest press, is a weight training exercise where a person presses a weight upwards while lying horizontally on a weight training bench. Although the bench press is a compound movement, the muscles primarily used are the pectoralis major, the anterior deltoids, and the triceps, among other stabilizing muscles. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting, powerlifting and strongman, consisting of a long bar, usually with weights attached at each end.
Bicep curls are a group of weight training exercises in which a person bends their arm towards their body at the elbow in order to make their biceps stronger.
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help the hip muscles.
The deadlift is a weight training exercise in which a loaded barbell or bar is lifted off the ground to the level of the hips, torso perpendicular to the floor, before being placed back on the ground. It is one of the three powerlifting exercises, along with the squat and bench press, as well as a frequent lift in strongman.
In strength training, rowing is an exercise where the purpose is to strengthen the muscles that draw the rower's arms toward the body as well as those that retract the scapulae and those that support the spine. When done on a rowing machine, rowing also exercises muscles that extend and support the legs. In all cases, the abdominal and lower back muscles must be used in order to support the body and prevent back injury.
The snatch is the first of two lifts contested in the sport of weightlifting followed by the clean and jerk. The objective of the snatch is to lift the barbell from the ground to overhead in one continuous motion. There are four main styles of snatch used: snatch, split snatch, power snatch, and muscle snatch. The full lift is the most common style used in competition, while power snatches and muscle snatches are mostly used for training purposes, and split snatches are rarely used. Any of these lifts can be performed from the floor, from the hang position, or from blocks. In competition, only lifts from the floor are allowed.
In weight training, a kettlebell is a cast-iron or cast-steel ball with a handle attached to the top. It is used to perform many types of exercises, including ballistic exercises that combine cardiovascular, strength and flexibility training. Kettlebells are the primary equipment used in the weight-lifting sport of kettlebell lifting.
A bent-over row is a weight training exercise that targets a variety of back muscles. Which ones are targeted varies on form. The bent over row is often used for both bodybuilding and powerlifting.
The following outline is provided as an overview of and topical guide to exercise:
Calf raises are a method of exercising the triceps surae, tibialis posterior, and peroneal muscles of the lower leg. The movement performed is plantar flexion, also called ankle extension.
A back extension is an exercise that works the lower back as well as the mid and upper back, specifically the Erector spinae. Each of us have two Erector spinae muscles, one of either side of the spine that run along the entire length of the spine. Erector spinae muscles are actually formed of three smaller muscles – spinalis, longissimus, and iliocostalis.
The rear delt raise, also known as the rear deltoid raise, or rear shoulder raise is an exercise in weight training. This exercise is an isolation exercise that heavily works the posterior deltoid muscle. The movement is primarily limited to the two shoulder joints: the glenohumeral joint and the scapulothoracic joint. Scapular movement will also cause movement in the sternoclavicular joint and acromioclavicular joint. If the elbow bends during the extension exercises, it gravitates into a rowing motion.
The leg raise is a strength training exercise which targets the iliopsoas. Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
The pullover is an exercise that is performed with either a dumbbell or a barbell. Pullovers can be made to affect either the chest or the back depending on how wide the grip is (barbell) and the position of the shoulders. A research done on the pullover movement using a barbell suggested more effect on the pectoralis major muscle as compared to the latissimus dorsi.
The Sumo deadlift is a variation of the conventional deadlift often adopted by powerlifters.
The 2018 CrossFit Games was the 12th CrossFit Games and held on August 1–5, 2018, at the Alliant Energy Center in Madison, Wisconsin, United States. The men's competition was won by Mathew Fraser, the women's by Tia-Clair Toomey, and CrossFit Mayhem Freedom won the Affiliate Cup.
