Ok, Leigh---chill with the mean-ness please. You may not be intending to come off as rude but it is certainly coming across that way in your posts.
While 15
pounds in a month is incorrect the rest is true---and proven. Muscle does weigh more than
fat and
cardio is a great way to burn off
fat.
I would suggest rather than telling people how 'horrible' their plan is that you would give them alternate plans to use and positive reinforcement.
