http://flexbelt.qolco.com - i'll still be posting some in the future to see how far ive come so subscribe to stay updated! i DO recommend this.. but if you have a lot of belly fat, this belt doesnt cut away the fat, it only strengthens the muscles, it still takes a good diet to actually see the definition... so try to cut down on fats and sugars the best you can and good luck!
