If you choose classical dance as a workout, you can expect some degree of health results, even if you do not target that particular goal.
If you learn ballet correctly and keep a slow, relaxed focus on progressing through the levels, you have a chance at reversing typical aging effects and rejuvenating your body.
Here's a nutshell version of how you speed up your calorie burning twenty-four/seven. How your body uses insulin and burns energy (instead of storing it as fat) depends upon lowering the glucose content in your muscles. The way to deplete the glucose in your muscles is by high intensity exertion, to the point of "muscle failure".
For example, when you execute a simple sequence of developpes (slow unfolding and lifting the leg) at the barre, you may feel shaky by the time the exercise ends. Your quad, or thigh muscle may be burning a little. This is good! You shake out your muscles to relax, and turn to the other side. This kind of exertion exhausts the big muscle, triggering the cellular events that uses insulin properly and burns energy.
The calorie burning speeds up as the muscles must now recover and rebuild. This requires a faster metabolism, even as you sleep.
Ballet classes have a combination of slow, intensive workouts, and short bursts of activity (fast footwork at the barre, and jumps) that require a different exertion from the cardiovascular system. This is similar to the Pace Express program, though not as exacting.
When you learn ballet arm movements (port de bras) you will feel the exertion on arm muscles as well. It's not the same as weight lifting, but done properly (which involves correct spinal posture) arm positions and movement in ballet is toning and sculpting. Everyone sculpts differently with exercise, but most people will see some visible result.
Running, jogging, and even brisk walking, done long term, can wear out joints. Learn the controlled workouts of ballet correctly, and you'll find out how to prevent joint injuries, and speed up your calorie burning at the same time.
