Next we have anaerobic meaning without oxygen it uses the stored energy in the muscles only and is short in duration an example would be the 200m hurdles. Finally we come to crosstraining. It encompasses both aerobic and anaerobic styles to make maximum use of all systems this would be accomplished by starting and stopping at different intervals. For example you could go running down a path then stop do push-ups then repeat the cycle again and again. Some of the benefits that can be achieved through exercise are lower blood pressure and an increase in stroke volume. Blood pressure (the force that the blood exerts on the vessel wall). Stroke volume ( the amount of blood that passes through the heart in one beat).By doing this the heart will become more efficient and will be able to recover faster after exercise is over. Remember the heart is a muscle the harder you work it the stronger it becomes. By working the muscles of the body they will naturally become stronger. They will be able to do more work for longer periods of time without fatigue or injury occurring. You will have a greater sense of mental awareness (a clear head).
