I live by this to all you ladies. I don't know how many times I tell my clients that weigh themselves how un-justified the number is.. If you are eating right and doing cardio and adding weights into your workout regiment.. the number on the scale may in the beginning go down but after you body starts to retain those sexy toning muscles.. the scale it not what you look at.. Muscle weighs more than fat.. so even though you are watching your diet an in crease you activity as you get more muscle on you body the weight you loose you will gain back in pound of lean muscle!!! Which is GOOD .. yes it is ok to have a lean toned muscle.. it help speed your metabolism up and burn fat.. so AGAIN the number on the scale is not the way to gauge progress.. the way your clothes fit will be the best way ! Other than that trust science behind proper way to get in shape!
