hello im new to this , i was just wondering if anyone could give me any help or advice on how to lose weight with my fitness pal.
i was also wondering why does my calories remains go up when i exercise? im eating my exercise calories again i thought you wasnt supposed to do that . should i be eating all of the goal calories or less ? and about how much less ? than you in advance
and for those who use just dance is that a good kind of exercise?
