Major variants: reverse ~ (curling the pelvis towards the shoulders), twisting ~ or side ~ (lifting one shoulder at a time; emphasis is on the obliques), cable ~ (pulling down on a cable machine while kneeling), sit-up ~ (have [chest] touch your knees), vertical crunch (propping up to dangle legs and pulling knees to the [ chest] or keeping ...
The Push/pull/legs split consists of three different workout routines: First, the push muscles consisting of the chest, anterior and lateral deltoids, and triceps. Then, the exercises for pull muscles (latissimus, trapezius, rhomboids, biceps, and rear deltoids) are worked on the second day. The final workout consists of training the muscles of ...
Several effective exercises target the muscles in the lower leg, including the calves, tibialis anterior, and other supporting muscles. Calf raises are a foundational exercise: standing with feet hip-width apart, you raise your heels off the ground and lower them back down, effectively strengthening the gastrocnemius and soleus muscles.
The parallel muscle architecture is found in muscles where the fibers are parallel to the force-generating axis. [1] These muscles are often used for fast or extensive movements and can be measured by the anatomical cross-sectional area (ACSA). [3] Parallel muscles can be further defined into three main categories: strap, fusiform, or fan-shaped.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).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 septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
There are several types of splines: [2] Parallel key spline where the sides of the equally spaced grooves are parallel in both directions, radial and axial. Involute spline where the sides of the equally spaced grooves are involute, as with an involute gear, but not as tall. The curves increase strength by decreasing stress concentrations.
