The wrist curl is a weight training exercise for developing just the wristflexor muscles of the forearm. It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" (also called wrist extension) to ensure equal development of the wrist flexor and wrist extensor muscles.
Weight training is a common type of strength training for developing the strength and size of skeletal muscles. It utilizes the force of gravity in the form of weighted bars, dumbbells or weight stacks in order to oppose the force generated by muscle through concentric or eccentric contraction. Weight training uses a variety of specialized equipment to target specific muscle groups and types of movement.
In human anatomy, the wrist is variously defined as 1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus and (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the flexor retinaculum, and the extensor retinaculum.
The forearm is the region of the upper limb between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm. It is homologous to the region of the leg that lies between the knee and the ankle joints, the crus.
Wrist curls can be performed with a dumbbell or with both hands holding a barbell. To perform a seated wrist curl, the lifter should be seated on a bench with knees bent and the forearm(s) resting on the thigh, or with forearms on a bench and hands hanging off the edge. The palm should be facing up and the hand should be free to move completely up and down. At the starting point, the wrist should be bent back so that the fingers are almost pointing down at the floor. In a steady motion, the lifter should raise the weight by using the forearm muscles to bring the hand up as far as possible. The forearm itself should remain resting on the thigh. Then the weight should be slowly lowered back down to the starting point.
The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand.
A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting and powerlifting, consisting of a long bar, usually with weights attached at each end.
A weight training bench is a piece of equipment that has a resemblance to a normal bench, but is designed for use in weight training.
To perform a standing wrist curl, a barbell can be held in both hands with the palms facing backward. The bar should be behind the lifter. The same motion should be performed as in the seated wrist curl. The range of motion will be smaller but the standing wrist curl offers the benefit of providing the most stress on the target muscles at their peak contraction.
Calisthenics is a form of exercise consisting of a variety of movements which exercise large muscle groups, such as running, standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises. They are intended to increase strength, fitness and flexibility, through movements such as pulling, pushing, bending, jumping, or swinging, using one's bodyweight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility and coordination.
The bench press is an upper-body weight training exercise in which the trainee presses a weight upwards while lying on a weight training bench. The exercise uses 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.
The term "biceps curl" may refer to any of a number of weight training exercises that target the biceps brachii muscle.
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 of a squat, 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.
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, then lowered to the ground. It is one of the three powerlifting exercises, along with the squat and bench press.
Lying triceps extensions, also known as skull crushers and French extensions or French presses, are a strength exercise used in many different forms of strength training. Lying triceps extensions are one of the most stimulating exercises to the entire triceps muscle group in the upper arm. It works the triceps from the elbow all the way to the latissimus dorsi. Due to its full use of the Triceps muscle group, the lying triceps extensions are used by many as part of their training regimen.
The 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. They are also the primary equipment used in the weight lifting sport of kettlebell lifting.
The good-morning is a weight-lifting exercise. It is known as a good morning because of the movement in the erector spinae which resembles the rise out of bed to stretch. 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 handstand push-up (press-up) - also called the vertical push-up (press-up) or the inverted push-up (press-up) also called "commandos"- is a type of push-up exercise where the body is positioned in a handstand. For a true handstand, the exercise is performed free-standing, held in the air. To prepare the strength until one has built adequate balance, the feet are often placed against a wall, held by a partner, or secured in some other way from falling. Handstand pushups require significant strength, as well as balance and control if performed free-standing.
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. It is a good exercise for increasing strength and size.
The pulldown exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
The following outline is provided as an overview of and topical guide to exercise:
The press, overhead press or shoulder press is a weight training exercise with many variations, typically performed while standing, in which a weight is pressed straight upwards from racking position until the arms are locked out overhead, while the legs, lower back and abs maintain balance. The exercise helps build muscular shoulders with bigger arms, and is one of the most difficult compound upper-body exercises.
A Cable fly or Cable flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle. Flies are used to work the muscles of the upper body. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles . Due to this leverage, fly exercises of all types have a large potential to damage the shoulder joint and its associated ligaments and the tendons of the muscles connecting to it. They should be done with caution and their effects first tested while using very light weights; which are gradually incremented after more strength is gained.
Calf raises are a method of exercising the gastrocnemius, tibialis posterior and soleus muscles of the lower leg. The movement performed is plantar flexion, a.k.a. ankle extension.
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 hang clean is a weightlifting exercise involving the use of a barbell to do a compound series of strength-building movements.
