Some gym's are promoting ways to get rid of problem areas. There is no spot reducing. If you have problem areas here are some suggestions.
Eat meat and vegetables, nuts and seeds, some fruit, little starch and NO sugar. Keep intake to levels that will support exercise but not body fat.
Practice and train major lifts: deadlift, clean, squat, presses, C&J, and snatch. Similarly, master the basics of gymnastics:pull-ups, dips, rope climb, push-ups, sit-ups, presses to handstands, pirouettes, flips, splits, and holds. Bike, run, swim, row, etc, hard and fast.
Five or six days per week mix these elements in as many combinations and patterns as creativity will allow. ROUTINE IS THE ENEMY. Keep workouts short and intense.
