HIIT to lose belly fat?

M_lifts

ive been reading up about HIIT and lifting heavy on one of the websites recommended here by people. Does it work? and did you manage to tighten up your tummy muscles? Im looking to tighten my belly post baby, its flat atm because of circui training but i want to get rid of my pouch!!. would love to know what you do and how heavy you lift etc. my strength training atm consists of light weights (6lbs), pushups, lunges, squats etc. also do the 30 day shred. Now i know its not enough but im working on it! would love some recommendations. I was always under the assumption that i would bulk up but i realise now that i was being ignorant and that wont happen! any tips would be fab!
