A theme which can be explored and expressed in a variety of different ways, existentialism is a belief based on the free will of the individual which suggests that all future development is created as a result of their own self determined actions.
People who do strengthening and toning exercises in an effort to trim fat from a certain area -- thighs, hips, stomach, or arms -- have the wrong idea. Although these exercises can help firm muscles, if the targeted area still carries an extra layer of fat, it won't look much different.
The Fire Hydrant exercise is extremely popular among those looking for a firmer butt. But just because it's a staple in most butt lift videos doesn't mean that athletes can't benefit from it. The concept of the Fire Hydrant exercise is simple. From an all-fours position, you lift your leg up to the side to engage your glutes. (Check out STACK's Glutes page.) The exercise specifically targets the gluteus medius, the muscle responsible for moving the leg sideways away from your body (technically termed abduction).
