Day 6 - elliptical again

Then it repeats, alternating strength w elliptical/treadmill days. If you google any of the exercise names, you'll probably see how the're done, though some results are different because no one agrees on names apparently?

These are designed to take about 30 minutes. I revise this every couple weeks as exercises become passe or weights need to be bumped up, but I've been pretty careful to keep each day's exercises fairly focused and not overlapping with other exercises on that day, and to allow aerobic and lactic acid recovery as needed, and to give respite for healing from session to session.

Oh I should also count the walking down 9 flight of stairs and back up again to our flat as part of the workout, my watch certainly does.
