The amount of sweat was unreal so can imagine how much more sweaty I would be if I ran or did a full blown workout 😳 highly recommend for any gym girlies or anyone wanting to lose water weight fast💕💧 Waist trainer, gym essentials, workout must have, waste trimmer, sweet sweat, Amazon finds LTKFindsUnder50 LTKFindsUnder100 LTKActive
