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 legs of tetrapods, the main group of terrestrial vertebrates (which also includes amphibious fish), have internal bones, with externally attached muscles for movement, and the basic form has three key joints: the shoulder joint, the knee joint, and the ankle joint, at which the foot is attached. Within this form there is much variation in ...
(EMG) is a method of detecting the electrical activity that occurs when muscles are activated, thus determining which muscles an animal uses for a given movement. This can be accomplished either by surface electrodes (usually in large animals) or implanted electrodes (often wires thinner than a human hair).
The main anatomical planes of the human body, including median (red), parasagittal (yellow), frontal or coronal plane (blue) and transverse or axial plane (green).. A fly or flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle.

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
The smallest flying vertebrates are the bee hummingbird and the bumblebee bat, both of which may weigh less than 2 grams (0.071 oz). They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm).

Kneeling is a basic human position where one or both knees touch the ground. It is used as a resting position, during childbirth and as an expression of reverence and submission. While kneeling, the angle between the legs can vary from zero to widely splayed out, flexibility permitting. It is common to kneel with one leg and squat with the ...
Seated calf raise. Bent-knee calf raises are frequently done in a seated position for comfort. Since the weight of the upper body is rested on the seat, resistance is frequently added. Using bodyweight, one leg could be draped across the other (through external rotation) to exercise unilaterally and double the weight lifted.
