The leg curl is an isolation exercise that targets the hamstring muscles. [1] The exercise involves flexing the lower leg against resistance towards the buttocks. There are three types of leg curls. There are seated leg curls, lying leg curls, and standing leg curls.
Other exercises that can be used to strengthen the hamstrings include the glute-ham raise and the deadlift.
Calisthenics or callisthenics (/ˌkælɪsˈθɛnɪks/) is a form of strength training consisting of a variety of movements that exercise large muscle groups, such as 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 body weight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility, and coordination.
In human anatomy, a hamstring is any one of the three posterior thigh muscles in between the hip and the knee. The hamstrings are susceptible to injury. In quadrupeds, the hamstring is the single large tendon found behind the knee or comparable area.
The term "biceps curl" refers to any of a number of weight training exercises that primarily targets the biceps brachii muscle. It may be performed using a barbell, dumbbell, resistance band, or other equipment.
Body for Life (BFL) is a 12-week nutrition and exercise program, and also an annual physique transformation competition. The program utilizes a low-fat high-protein diet. It was created by Bill Phillips, a former competitive bodybuilder and previous owner of EAS, a manufacturer of nutritional supplements. It has been popularized by a bestselling book of the same name.
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 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 your 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.
An elliptical trainer or cross-trainer is a stationary exercise machine used to stair climb, walk, or run without causing excessive pressure to the joints, hence decreasing the risk of impact injuries. For this reason, people with some injuries can use an elliptical to stay fit, as the low impact affects them little. Elliptical trainers offer a non-impact cardiovascular workout that can vary from light to high intensity based on the speed of the exercise and the resistance preference set by the user.
Anterior cruciate ligament reconstruction is a surgical tissue graft replacement of the anterior cruciate ligament, located in the knee, to restore its function after an injury. The torn ligament can either be removed from the knee, or preserved before reconstruction through an arthroscopic procedure. ACL repair is also a surgical option. This involves repairing the ACL by re-attaching it, instead of performing a reconstruction. Theoretical advantages of repair include faster recovery and a lack of donor site morbidity, but randomised controlled trials and long-term data regarding re-rupture rates using contemporary surgical techniques are lacking.
A lunge can refer to any position of the human body where one leg is positioned forward with knee bent and foot flat on the ground while the other leg is positioned behind. It is used by athletes in cross-training for sports, by weight-trainers as a fitness exercise, and by practitioners of yoga as part of an asana regimen.
A split is a physical position in which the legs are in line with each other and extended in opposite directions. Splits are commonly performed in various athletic activities, including dance, figure skating, gymnastics, contortionism, synchronized swimming, cheerleading, martial arts, aerial arts and yoga as exercise, where a front split is named Hanumanasana and a side split is named Samakonasana. A person who has assumed a split position is said to be "in a split", "doing a split", or "doing the splits".
The wrist curl is a weight training exercise for developing just the wrist flexor muscles of the forearm. It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" to ensure equal development of the wrist flexor and wrist extensor muscles.
The pull-down 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 leg extension is a resistance weight training exercise that targets the quadriceps muscle in the legs. The exercise is done using a machine called the Leg Extension Machine. There are various manufacturers of these machines and each one is slightly different. Most gym and weight rooms will have the machine in their facility. The leg extension is an isolated exercise targeting one specific muscle group, the quadriceps. It should not be considered as a total leg workout, such as the squat or deadlift.
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.
Hyperextension means a movement where extension is performed at any joint beyond its normal range of motion.
An eccentric contraction is the motion of an active muscle while it is lengthening under load. Eccentric training is repetitively doing eccentric muscle contractions. For example, in a biceps curl the action of lowering the dumbbell back down from the lift is the eccentric phase of that exercise — as long as the dumbbell is lowered slowly rather than letting it drop.
A kick is a skill in association football in which a player strikes the ball with their foot. Association football, more commonly referred to as football and also known as soccer, is a sport played world-wide, with up to 265 million people around the world participating on a yearly basis. Kicking is one of the most difficult skills to acquire in football. This skill is also vitally important, as kicking is the way in which passes are made and the primary means by which goals are scored.
The Nordic hamstring curl (NHC) is an exercise in which a person kneels with their feet fixed in position and lowers their body by extending the knee. It reduces hamstring injuries in athletes, and is commonly used as a form of injury prevention. NHC increases strength of the hamstrings and length of the fascia, sprint speed, and change of direction ability. It is debated whether NHC is an open or closed chain exercise. NHC has been compared to the razor hamstring curl.
