Ahh ok. I exercise a little easier than that, I use a machine that varies
its intensity (using a Polar monitor :-) to keep my heart rate between 130
and 163.. usually it ends up staying around 160 for most of the workout.
My goals are perhaps a bit different, I prefer the longer workouts since I
want to improve my endurance for sports like mountain biking where you have
to sustain a moderate to high level of exertion for an hour or longer.

I am not planning on any certain uploading date either; I just am questioning
the claimed life extending qualities of weight training in addition to good
aerobic exercise. Especially for younger people.
