First I would like to talk about your training strategies. In the past you would have been taught to do low to medium aerobic training for about 30 minutes a day at a steady pace! Will forget that, new research suggests the old style of cardio training is ineffective and a waste of time!
New techniques research has discovered encourage you to exercise in bursts of exertion followed by a short recovery and to add as much variety as possible. This is what your body was designed for. Sports such as Basketball or squash in fact most sports use this stop and go movement. I know from my personal experience that I can go for long runs and feel reasonably fit but when I go to play Basketball, I am soon tired and exhausted. This is because my heart is not used to being fully exerted to its maximum rate. After an endurance run my body is just exhausted and my joints are sometimes sore - I often have that feeling I could have done more though. Go and do some training that really makes your heart work such as a fast sprint between lamp posts and alternately jog the next one and you feel on top of the world.
Endurance training can cause muscle wasting and any number of physical problems. Train in stop and go type movements with plenty of variety and your body will increase its anti oxidant production. Another great advantage for those of you looking at losing weight is you increase your metabolism and your heart learns to respond to stress a lot better.
Doing hill sprints instead of running on the flat makes you feel as if you have really done a workout. It is a very efficient form of exercise you feel great and it is much more interesting meaning you will more than likely keep it up.
