I know this is off topic, but i have a question about
exercising.  I began working out twice a week (I know
not really enough, but it is all I can do at this
time).  I usually do 30-40 minutes of cardio followed
by weight training.  I simply want to increase muscle
mass.  Is it better to do more reps at a lower weight,
or increase the weight as it becomes easier?  Also, I
use mostly weight machines, not free weights.  Is
there any difference, benefits, negatives, etc.
between them?  Please feel free to respond privately
so as not to take up list space.
Thanks
Jane
