Fingers to heel oblique touches 3 sets, each set to failure.
Overhead abdominal crunches 3 sets, each to failure.
Reverse abdominal crunches 3 sets, each to positive failure.
Is this enough to burn the fat? I dont have the time/equipment for cardio, I think diet sucks aswell (getting about 1000-1500 calories a day), I'm classed as 'underweight' in BMI terms even though Im 5ft 6in and weigh 132lbs.
Is this ab exercise plan good enough?
Does intake of calories need to increase?
Is cardio really necessary to get those abs I am desperate for?
Any help would be great
