do resistance training (i.e. lift weights) and do some cardio.
Lunges and deadlifts = lifting weights/resistance training.
You can't use exercises to selectivelt target body areas fro fat headhunter. Liek PFunk said, improve your eating habits, get rid of the sugars and saturated fats.
Get into some high intensity training; interval sprinting/hill sprints, circuit-style resistance training using big exercises like squats, deadlifts, lunges, cleans; and high reps of bodyweight exercises like chin-ups, push-ups, burpees.
If you're serious about it, get some professional advice from someone at your gym
