This is great advice from Joe Donnelly:
Some key factors why you are not losing as much bodyfat as you want or achieving the physique you desire:
1) Missing meals or starving the body. Everyday I hear a story about some women saying I’m only eating 600 calories and doing an hour of cardio and I cant lose any weight. No shit. You are starving the body and it will refuse to let any fat go when starved.
2) You are doing too much cardio. If you want to get fit you need to lift. ESPECIALLY YOU WOMEN!! Lift, Lift, Lift. 70% of your efforts need to be with weights. Adding muscle increases metabolism and forces the body to burn more calories during the day. Cardio makes you soft and eats away at muscle if that is all that you do!
