Vinny Guadagnino has been on a diet and exercise program for just 3 weeks, and he’s already showing MAJOR results. The Jersey Shore star took to his Instagram last night to show his before and after photos, and it’s crazy how much can change in such little time. That should be motivation to anyone hoping to get their body right! Check out the pics in the gallery. Keep up the good work, Vin!
