An outdoor knee raise station

A power tower, also known as a knee raise station, and as a captain's chair, is a piece of exercise equipment that allows one to build upper body and abdominal muscle strength. When only the forearm pads alone are used for performing abdominal exercises, the power tower requires minimal[ clarification needed ] arm strength as it is stable and movement occurs in the hips and torso. The equipment commonly has a backrest and forearm rests that form the chair, with vertical handles at the ends of the arm rests. The word "power" comes from the addition of other powerful arm exercises such as parallel horizontal handles for performing dips, a pull-up bar attached to the top for chin-ups and pull-ups, and push-up handles that are usually found on the bottom for Atlas ("deep") push-ups.

Exercises

The knee raise exercise will work the lower abdominals, and can also work the obliques (see abdominal external oblique muscle and abdominal internal oblique muscle) if one twists the torso during the exercise. This version of the knee raise has been praised by fitness communities[ who? ] for its effectiveness, as working the abdominal muscles. Previous research has shown that a captain's chair knee raise will elicit a greater electromyography (EMG) response than the standard crunch. [1] This means that the knee raise in the captain's chair will have more activation in the muscle than the standard crunch. However, 2013 research has shown that it has the same EMG activity as the standard crunch. [2] This newer research is yet to be published. One aspect that both researches agree on is that there is no difference in activation of upper rectus abdominis and lower rectus abdominis, as it is speculated that the muscle acts as one and cannot be differentiated.

Advanced users may increase resistance by wearing a weighted vest or ankle weights, holding a dumbbell between the feet, kettlebells on the toes, a resistance band tied from one's feet to the bottom of the tower, or other heavy[ clarification needed ] weights.

The latissimus dorsi is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. The word latissimus dorsi comes from Latin and means "broadest [muscle] of the back", from "latissimus" and "dorsum". The pair of muscles are commonly known as "lats", especially among bodybuilders.

<span class="mw-page-title-main">Push-up</span> Calisthenics exercise

The push-up is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, and some martial arts disciplines. Variations of push-ups, such as wide-arm push-ups, diamond push-ups target specific muscle groups and provide further challenges.

<span class="mw-page-title-main">Sit-up</span> Abdominal endurance training exercise

The sit-up is an abdominal endurance training exercise to strengthen, tighten and tone the abdominal muscles. It is similar to a crunch, but sit-ups have a fuller range of motion and condition additional muscles.

<span class="mw-page-title-main">Aponeurosis</span> Tissue which connects muscles to other organs

An aponeurosis is a flattened tendon by which muscle attaches to bone or fascia. Aponeuroses exhibit an ordered arrangement of collagen fibres, thus attaining high tensile strength in a particular direction while being vulnerable to tensional or shear forces in other directions. They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves. When dissected, aponeuroses are papery and peel off by sections. The primary regions with thick aponeuroses are in the ventral abdominal region, the dorsal lumbar region, the ventriculus in birds, and the palmar (palms) and plantar (soles) regions.

A dip bar is a piece of fitness equipment that consists of a U-shaped bar, usually about 25 mm (1 in) in diameter, which surrounds the user's body at the waist. It is designed for the performance of, and named after, the dip exercise.

<span class="mw-page-title-main">Rectus abdominis muscle</span> Paired straight muscle

The rectus abdominis muscle, also known as the "abdominal muscle" or simply the "abs", is a pair of segmented skeletal muscle on the ventral aspect of a person's abdomen. The paired muscle is separated at the midline by a band of dense connective tissue called the linea alba, and the connective tissue defining each lateral margin of the rectus abdominus is the linea semilunaris. The muscle extends from the pubic symphysis, pubic crest and pubic tubercle inferiorly, to the xiphoid process and costal cartilages of the 5th–7th ribs superiorly.

<span class="mw-page-title-main">Transverse abdominal muscle</span> Muscle of the abdominal area

The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral abdominal wall, deep to the internal oblique muscle. It is thought by most fitness instructors to be a significant component of the core.

<span class="mw-page-title-main">Lying triceps extension</span> Strength exercise

The lying triceps extension, also known as skull crusher and French extension or French press, is a strength exercise used in many different forms of strength training. It is one of the most stimulating exercises to the entire triceps muscle group in the upper arm, and 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.

Abdominal exercises are a type of strength exercise that affect the abdominal muscles. Human abdominal consist of four muscles which are the rectus abdomens, internal oblique, external oblique, and transversus abdominis. When performing abdominal exercises it is important to understand the effects, functions, the types of exercises, and think about how to perform this exercise safely.

<span class="mw-page-title-main">Pull-up (exercise)</span> Upper-body compound pulling exercise

A pull-up is an upper-body strength exercise. The pull-up is a closed-chain movement where the body is suspended by the hands, gripping a bar or other implement at a distance typically wider than shoulder-width, and pulled up. As this happens, the elbows flex and the shoulders adduct and extend to bring the elbows to the torso.

<span class="mw-page-title-main">Muscle-up</span> Bodyweight exercise

The muscle-up is an intermediate strength training exercise, within the domain of calisthenics. It is a combination routine of a radial pull-up followed by a dip. Variations exist for the rings as well as the bar.

<span class="mw-page-title-main">Diastasis recti</span> Medical condition

Diastasis recti, or rectus abdominis diastasis, is defined as a gap of about 2.7 cm or greater between the two sides of the rectus abdominis muscle. The distance between the right and left rectus abdominis muscles is created by the stretching of the linea alba, a connective collagen sheath created by the aponeurosis insertions of the transverse abdominis, internal oblique, and external oblique. This condition has no associated morbidity or mortality. Physical therapy is often required to repair this separation and surgery is an option for more severe cases. Standard exercise rarely results in complete healing of the separated muscles.

<span class="mw-page-title-main">Inverted row</span>

The inverted row is an exercise in calisthenics. It primarily works the muscles of the upper back—the trapezius and latissimus dorsi—as well as the biceps as a secondary muscle group. The supine row is normally carried out in three to five sets, but repetitions depend on the type of training a lifter is using to make their required gains. This exercise is lighter on the joints compared to weighted rows. The exercise can also be performed with mixed, underhand, or overhand grips with either wide or narrow hand placement. The exercise is also known under various names such as supine row, bodyweight row, Australian pull up or "horizontal pull-up".

<span class="mw-page-title-main">Leg raise</span> Strength training exercise

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.
