Powerlifting is a strength sport. It resembles the sport of Olympic weightlifting, as both disciplines involve lifting weights in three attempts. Powerlifting evolved from a sport known as 'odd lifts' which followed the same three attempt format but used a wide variety of events akin to Strongman events. Eventually odd lifts became standardized to the three events squat, bench press, and deadlift. They can compete raw or equipped (that is, with or without certain supportive equipment).

 

Training
 
Powerlifting requires specialized training techniques that are focused on strength and explosive power. Traditional training methods dictated low repetitions with maximal weight. These practices are still true today, however, training methods have advanced to include emphasis on explosive power. This may be achieved through dynamic exercises which utilize lighter weight and alternating repetition patterns.
The squat, bench press and deadlift are the three main lifts in competition. In order to maximize their effectiveness at these lifts athletes typically train with a cyclical routine. A common split is to give each of the three lifts a day where exercises designed to increase that lift are performed or to treat the deadlift and squat as one lift and perform upper and lower body sessions, however there are many different methods. Training consists of mostly compound lifts (a compound lift being any movement across multiple joints) in the 1-5 repetition range.
 
Using a lower repetition range allows for the use of a higher weight and higher maximum force development. This occurs because usage of a higher weight (80-100% of maximum) will ensure that the limitation of weight lifted is limited by neural efficiency (how many muscle fibres the nervous system can trigger), rather than by exhaustion of the muscle fibers in the area. Higher reps in the 6-12 range are used for hypertrophy (size building/bodybuilding) and the 12-20+ range is typically used more for endurance athletes. It is not necessary to train for size or endurance because neither matter in a competition.
A well known training method is known as the Westside Barbell method developed by Louie Simmons, or the high volume routines developed by Boris Sheiko. Other approaches to powerlifting training include Mike Tuscherers RPE-based training, and the classical progressive overload approach. Western linear periodization was a powerlifting staple in the USA before the Westside Barbell method gained popularity. Among many elite-level powerlifters in the US, hybrids between Westside and russian accumulation/intensification methods are popular. The programs also tend to be very personalized.
 

Isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. This is reflected in the name; the term "isometric" combines Greek the prefixes "iso" (same) with "metric" (distance), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied.[1] This is in contrast to isotonic contractions, in which the contraction strength does not change, though the muscle length and joint angle do.
Isometric resistance

Resistance in isometric exercises typically involve contractions of the muscle using:
The body's own structure and ground
Structural items (e.g., pushing against a fence)
Free weights, weights machines or elastic equipment (e.g. holding a weight in a fixed position)
Pressure plate type equipment that has a digital display of maximal force.
Depending on the goal of the exercise, the exertion can be maximal, or sub-maximal.

Weight training is a common type of strength training for developing the strength and size of skeletal muscles. It uses the weight force of gravity (in the form of weighted bars, dumbbells or weight stacks) 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.

 
Weight training differs from bodybuilding, Olympic weightlifting, powerlifting, and strongman, which are sports rather than forms of exercise. Weight training, however, is often part of the athlete's training regimen.
 
Weight training versus other types of exercise
 
Strength training is an inclusive term that describes all exercises devoted toward increasing physical strength. Weight training is a type of strength training that uses weights rather than elastic, Eccentric Training or muscular resistance to increase strength. Endurance training is associated with aerobic exercise while flexibility training is associated with stretching exercise like yoga or pilates. Weight training is often used as a synonym for strength training, but is actually a specific type within the more inclusive category.
 
Weight training versus resistance training
Resistance training involves the application of elastic or hydraulic resistance to muscle contraction rather than gravity. Weight training provides the majority of the resistance at the beginning, initiation joint angle of the movement, when the muscle must overcome the inertia of the weight's mass. After this point the overall resistance alters depending on the angle of the joint. In comparison, hydraulic resistance provides a fixed amount of resistance throughout the range of motion, depending on the speed of the movement. Elastic resistance provides the greatest resistance at the end of the motion, when the elastic element is stretched to the greatest extent.
 
Weight training versus isometric training
Isometric exercise provides a fixed amount of resistance based on the force output of the muscle. This strengthens the muscle at the specific joint angle at which the isometric exercise occurs, with some lesser gains in strength also occurring at proximal joint angles.[4] In comparison, weight training strengthens the muscle throughout the range of motion the joint is trained in, causing an increase in physical strength from the initiating through to terminating joint angle.
 
Weight training and bodybuilding
Although weight training is similar to bodybuilding, they have different objectives. Bodybuilders use weight training to develop their muscles for size, shape, and symmetry regardless of any increase in strength for competition in bodybuilding contests; they train to maximize their muscular size and develop extremely low levels of body fat. In contrast, many weight trainers train to improve their strength and anaerobic endurance while not giving special attention to reducing body fat far below normal.
The bodybuilding community has been the source of many of weight training's principles, techniques, vocabulary, and customs. Weight training does allow tremendous flexibility in exercises and weights which can allow bodybuilders to target specific muscles and muscle groups, as well as attain specific goals. Not all bodybuilding is undertaken to compete in bodybuilding contests, and, in fact the vast majority of bodybuilders never compete, but bodybuild for their own personal reasons.
 

Back extension exercises are back strengthening exercises that are very important in counter balancing the many forward bending exercises we do in Pilates. Additionally, the constant forward bending and computer slouching of our daily lives create weak backs that lead to back pain. Everyone needs to know a few back extension exercises they can use to strengthen their back muscles, prevent back pain, and promote uniform muscular development front to back.Back extension is a strength training exercise. It is done for strengthening lower back muscles.
 
 
Using equipment, it can be done by lowering the body from a stand and raising back using the roman chair, or using a back extension machine where body pushes a weight backwards.
Without using equipment, it is done by lying face-down on the floor, and lifting the torso and arms together up off the floor. This is also called hyperextension.
 

Resistance training is a form of strength training in which each effort is performed against a specific opposing force generated by resistance (i.e. resistance to being pushed, squeezed, stretched or bent). Exercises are isotonic if a body part is moving against the force. Exercises are isometric if a body part is holding still against the force. Resistance exercise is used to develop the strength and size of skeletal muscles. Properly performed, resistance training can provide significant functional benefits and improvement in overall health and well-being.

The goal of resistance training, according to the American Sports Medicine Institute (ASMI), is to "gradually and progressively overload the musculature system so it gets stronger." Research shows that regular resistance training will strengthen and tone muscles and increase bone mass. Resistance training should not be confused with weightlifting, powerlifting or bodybuilding, which are competitive sports involving different types of strength training with non-elastic forces such as gravity (weight training or cliometrics) rather an immovable resistance (isometrics, usually the body's own muscles or a structural feature such as a door-frame). Full range of motion is important in resistance training because muscle overload occurs only at the specific joint angles where the muscle is worked.
