Diet is a very important part to abs. But also you need a steady mix of cardio and weight lifting. When your body gets into a routine your muscle will stop building at the same rate it was. Which really turns alot of people away from working out because you see less and less results. Thats why doing inclinced and declinced presses or crunch's help alot. For strength training, there is nothing better than good crisp push-ups, it doesnt have to be many, you just cant be easy on yourself. It will be hard at first you just have to do as many as you can. So set different goals for yourself in that aspect. Say you can only do 5 your first week, make it 7 the next. Reaching goals is a very good way to keep motivated so dont make them out of reach. As far as abs go the best advice I could give is this, find a healthy diet that fits your life style, because it can be very expensive. Stay dedicated to your goals, which is the hardest thing to do. And switch up your work-outs for it. The best one Ive found is this. Day 1: "Rocky" style sit ups. Put both hands behind your hand at all times, then when you raise for the sit up touch your right elbow to your left knee and then your left elbow to your right knee, and thats one. Day 2: If you have a friend with you the declined bench with a medicine ball. Start off sitting at the top of the bench, then when ready your partner throws the ball to you, lay completly back and touch the ball to the ground, then sit back up throw the ball to your partner and repeat. Also with this one, you can twist your body right after sitting back up, touch the ball to the left side of your body, then to the right, helps with the side abs. Day 3: Weighted crunches, there are two weighs you can do this one, take a weight you are comfortable with start off laying flat on your back with the weight resting on your chest. slowly raise while keeping your back straight. Or if your gym/home workout has the equipment lean forward with a weight that you are holding to your chest, again while keeping your back straight and rise. Any variation of those really works for me. And as far as core workouts go, squats, deadlifts, bench and leg press all do a great job. For chest exercise's and arms, I would suggest inclined and declind dumbell press. Regualr bench press and inclinced bench press. My schedule for arms and chest usually goes as follows: Start with chest because most chest exercise also work out arms Biceps and triceps, Then from there go to a set of dumbell curls, then to a set of preacher curls. Make sure not to do all of these at once, because really if you keep your body guessing you will see more results faster. And try to give at least one days rest to every muscle group, you dont want to burn yourself out to fast... Im not suggesting that you do this without consulting others, because this is just what works for me. And as far as setting goals, I started working out in 10th grade, I am now 20 years old. When I started I couldnt bench more than 125lbs... after a long time of dedication I am now at 295lbs 5 times.. So just do your best to make time for it, and find a friend who will keep you in line.
