Exercise intensity

When I used to exercise longer and harder I had hopes of reaching the nicely round number of burning 25 of the cross-trainer's idea of calories per minute on average. Not finding myself getting much beyond 23, I slacked off to see what a gentler but daily regime would achieve and was eventually disappointed to find myself tending to not quite manage even 20. These days with my daily half-hour workouts an overall burn rate of 19½ of these calories per minute is typical. Perhaps it will stabilize there. By happy coincidence the BBC's longer Wednesday Workout playlists on Radio 2 appear to have been replaced by half-hour Workout Wednesday playlists on Radio 1.

By any reasonable standard I do enough aerobic exercise. For vigorous exercise people are generally encouraged to do at least 1¼ hours each week and I typically manage 3 hours. Though, with now having the cross-trainer on a slightly lower resistance, on average 60% of its maximum, I wonder if I am not getting much in the way of strength training included. I had another look at the Mayo Clinic's exercise intensity guidelines regarding heart rate. Since I settled into exercise and lost weight my heart rate is typically under 60bpm at rest. In my mid-40's my maximum rate's above 170bpm and after a fairly uniform workout mine's above 150bpm, near the high end of my target zone for vigorous exercise. That tells me that I should not increase the machine's resistance level.

In short, despite missing what were always fairly arbitrary goals, at present I think I exercise hard enough for long enough to not need to make any changes.
