actually I think it depends. My gf signed up for some dance and
fitness course too... and from what I observed of the exercises
there, there are lots of bodyweight exercises and cardio. That time
before I went Germany, when I was still a little fitter than now, I
went for a few sessions with my gf (support her mah)... Muscles
ached really badly after the first session... Just that for me,
from the 2nd session onwards, my muscles were already well adapted
and there were no problems from then...
But I don't like... Not my kind of exercise....
