Electronic pulses from our brains travel down nerves and make the muscles contract, they are joined onto cartilage and that onto bones that make us move, the muscles store glogegen in muscle cells that give them energy to move the more water a muscle holds the more energy it can have
it is in your bum
Ski sits work your Quadriceps, Hamstrings, Gluteals and Gastrocnemius(calf).
Biceps flex the elbow. Quadriceps extend the knee. Hamstrings flex the knee. Deltoids abduct the humerus. Gluteus maximus extends the femur. Gastrocnemius flexes the knee and plantar flexes the ankle. Abdominal obliques flex and rotate the trunk. Pectoralis major adducts the humerus. Trapezius does many actions, mostly adduct and upwardly rotates scapula. Erector spinae erect the spine.
Quadriceps
When performing the lateral step-up, you will be using the quadriceps and knees, glutes and hips, and hamstrings. Most of the lower body will benefit from this exercise.
it works your biceps and triceps along with your breast
Depends on what stroke you use but mainly the Triceps, Biceps, Quadriceps, Trapezius, and the Hamstrings.
No it is not true, the antagonist muscle to the biceps is the triceps. You have to think of what muscles will have to release in order to allow contraction, another example would be when the quadriceps contract, your hamstrings must release otherwise the work of the muscles would contradict one another.
It is 3/2
hamstrings and the quadriceps
No, the hamstring is posterior to the quadriceps.
People use their abdominals, biceps, triceps, deltoids, hamstrings, and obliques to stretch in soccer.
