Most of the lactic acid remaining after exercise is converted back into glucose by the liver through a process called gluconeogenesis. This glucose can then be used as energy by the body or stored as glycogen in the muscles and liver for future use.
pyruvic acid
During energy production without oxygen, glucose is converted into lactic acid through a process called anaerobic glycolysis. This occurs in muscle cells during intense exercise when oxygen supply is limited.
During physical exercise, the stored energy in carbohydrates, fats, and other molecules in your cells is converted through a series of chemical reactions into adenosine triphosphate (ATP), which is the energy currency used for muscle contraction. This conversion process provides the energy needed for muscle contractions and movement.
During intense exercise, pyruvic acid in muscle cells is converted into lactate by the process of anaerobic glycolysis. This allows for the regeneration of NAD+ to keep glycolysis functioning when oxygen is limited.
Excess pyruvic acid is produced during prolonged strenuous exercise because the body relies more heavily on anaerobic respiration due to the insufficient supply of oxygen to meet energy demands. This causes an accumulation of pyruvate, the end product of glycolysis, which is then converted to lactic acid in order to regenerate NAD+ for continued ATP production.
Energy
There are no exercise videos available using the stairmaster because there is no need for them. The stairmaster restricts movements to one repetitive movement.
Do you mean physical exercise or mental? If physical then Nike+, Runkeeper, Fleetly, or Gym Hero are all available apps. If mental exercise is meant then AnQ, Lumina, or Speedbrains are viable options.
Energy
Most of the lactic acid remaining after exercise is converted back into glucose by the liver through a process called gluconeogenesis. This glucose can then be used as energy by the body or stored as glycogen in the muscles and liver for future use.
Ketone bodies are produced in the liver when there is insufficient glucose available for energy production. This can happen during fasting, prolonged exercise, low-carbohydrate diets (such as ketogenic diets), or in untreated diabetes mellitus. The process is known as ketogenesis.
Lactic acid is the molecule produced during intense exercise when there is insufficient oxygen to meet energy demands. This leads to the accumulation of lactic acid in the muscles, causing fatigue and contributing to the oxygen debt that needs to be repaid post-exercise.
There is a wide selection of home use exercise equipment that is available these days. This includes exercise bikes, treadmills, steppers, rowing machines and more. Many weight machines and free weights are also available.

Currently there are no exercise games available on the Playstation 3 platform. However, developer EA has plans to develope one similar to there Active game for the Wii.
Exercise requires and uses up energy. The sugar/carbohydrates in your body/blood is converted to energy for this. This removes blood sugar from your system lowering blood sugar.
