loosing fat

[Swizz]

I have recently 'cleaned up' my diet and I do about 15-20mins a day of simple stretches and exercising. I feel I never have the time/enegery/motivation to go for a run or anything like that., but is that the best way to loose weight? I feel and look a bit slimmer, but my lower body is still very untoned. Any help would be appreciated! Thanks.
