Curves member here too, been on and off for a few years now currently just getting back into it after having my son 6 months ago.. I originally joined to help myself quit smoking & figured having some form of exercise as back up would help with the process & try to eliminate weight gain that most people experience after giving up ciggarettes.. although I never really lost any weight I actually felt the best and looked the best I had in a while, I fit into size 10 clothes back then which was awsum as i've always been a 12 .. after having my baby im now a 14!! so i hope i can get back to how i felt before the pregnancy..
A few things ive learnt along the way, dont try fad diets.. they never last.. if ur after a rapid loss the shakes do work & apparently they provide you with all the minerals etc that ur body needs.. but they are no designed for long term use and you have to be ready to eat healthy foods and keep up ur 30 minutes if you want to keep the weight off once you stop them..oh and beware of the "fat free" or low fat products.. sometimes they are high in sugar content and apparently sugar is fat if its not burned off.. so look for sugar free products too!
Also for those that are stressing over not losing much weight.. your losing the cm's your toning up and looking good.. the reason why the scales are tricking you is because youve gained muscle which weighs more then fat does.. but at the end of the day ur doing great because losing fat is a fantastic achievement ! Curves is great for toning up etc.. but I do believe you need some normal paced excercise to burn fat rather then high intensity workouts to gain muscle.. like walking for example.. if u can find time to have a 30 minute walk i think it will make the scales show u some better numbers !
These are just my thoughts and opinions from my experiences and the things ive learnt along the way - just puttin it out there for yall
