Update.....and intervals

As I said I'm a bit short of time to do much here at the moment.

However, if you are interested, I've put up a box on the right of the screen there which highlights recent blog posts that I think are worth sharing. For example there are a couple of recent studies on interval training that you might like to look at:

Effect of interval versus continuous training on cardiorespiratory and mitochondrial functions: relationship to aerobic performance improvements in sedentary subjects - These results suggest that fluctuations of workload and oxygen uptake during training sessions, rather than exercise duration or global energy expenditure, are key factors in improving muscle oxidative capacities. In an integrative view, IT seems optimal in maximizing both peripheral muscle and central cardiorespiratory adaptations, permitting significant functional improvement.

Sprint interval and traditional endurance training induce similar improvements in peripheral arterial stiffness and flow-mediated dilation in healthy humans - We conclude that SIT (sprint interval training) is a time-efficient strategy to elicit improvements in peripheral vascular structure and function that are comparable to ET (Endurance Training). However, alterations in central artery distensibility may require a longer training stimuli and/or greater initial vascular stiffness than observed in this group of healthy subjects.
