Knickerbocker's theory does not explain why the first firm in an oligopoly decides to undertake FDI rather than to export or license. (Hills, 2008) also suggested that the imitative theory does not address the issue of whether FDI is more efficient than exporting or licensing for expanding abroad.
Isometrically, the lower back, the upper back, the abdominals, the trunk muscles, the costal muscles, and the shoulders and arms are all essential to the exercise and thus are trained when squatting with the proper form.
Squats primarily target your thighs and derriere, but they also tone your hamstrings and calves. Your back muscles and abs work to steady your spine during the movement, making squats a core strengthener. Even your breathing muscles get a workout when you're squatting. Squats are a great all-around thigh toner.
