In weight training, the shoulder shrug (usually called simply the shrug) is an exercise used to develop the upper trapezius muscle. [ 1 ] [ 2 ] Form and execution
In this position, the extended arms are swung from one side to another in a twisting motion with or without weight. Equipment: body weight, kettlebell, medicine ball, or dumbbell. Major variants: back kept off the floor at 45° angle, back rested on exercise ball, feet resting on the floor, anchored or kept off the floor.
These are deep breathing, which results in increased intra-abdominal pressure; and post-activation potentation, which is the enhanced activation of the nervous system and increased muscle fibre recruitment. Power training programmes may be shaped to increase the trainee's ability to apply power in general, to meet sports specific criteria, or both.
The hamstrings, a muscle group at the back of the thigh, also get a workout. "During jumping jacks, the hamstrings control the knee movement and provide the effort needed to jump," Thompson says.
It is often thought to have been named after the (upper fibres of the) trapezius muscles, the muscle it was designed to train, with shoulder shrugs. In addition to shrugs, the bar is also used for trapbar deadlift, [1] trapbar jumps, overhead/military presses, upright rows or "high pulls," and stiff leg deadlifts. Its design has since changed ...
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping. [ 1 ]
Close grip dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. [1] Wide shoulder width dips place additional emphasis on the pectoral muscles , similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the triceps.
A training sled, weight sled, or fitness sled is a piece of exercise equipment that provides resistance as the user pushes, pulls, or otherwise moves the sled along a flat surface. [1] Commercial sleds allow easily adjusting the weight or resistance and are supported on feet or wheels that allow moving the sled across surfaces such as grass ...
