  • Anaerobic exercise is also called strength or Resistance training and can firm, strengthen, and tone your muscles, as well as improve bone strength, Balance, and Coordination.

Anaerobic exercise also include weight training, functional training, eccentric training, Interval training, sprinting and high-intensity interval training increase short-term muscle strength.
  • Flexibility exercises stretch and lengthen your muscles. Activities such as stretching help to improve joint joint flexibility and keep muscles limber. The goal is to improve the range of motion which can reduce the chance of injury.

Sometimes the terms ‘dynamic’ and ‘static’ are used. ‘Dynamic’ exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly (during the exercise).
