Doing regular push ups with proper form and breathing techniques is one of the simplest, and best exercises you can do for  your chest, but weighted pushups puts extra strain on your muscles that encourages them to break down, then build up stronger, but is not recommended for just starting out, as it could result in muscle tears and other injuries, that will only set you back from accomplishing your fitness goals.  To do weighted pushups, strap on a weight to increase the weight of your torso. Do 3 sets of 15 pushups per workout. If you find it easy to do more than 15 at a time, add more weight. You can also make the standard pushup tougher by doing rotating pushups and lifting dumbbells at the same time. Start in a regular pushup position, but instead of having your palms on the ground, hold a dumbbell in each hand. Lower your body to the floor, then push up up with one hand and raise the other toward the sky, rotating your body sideways as you do so. Lower it to the floor and push down again, then push up with the other hand and rotate in the other direction. You'll need two exercise benches. Try this exercise first without the weight and work your way up to doing it with weight added. Place your hands on one bench, and rest your crossed feet on the other. Your butt and thighs should be positioned over the gap between the benches. Once you have mastered the dip, you can begin to place a weight across your thighs. Make sure it's secure before you begin.  Keeping your back straight, "dip" your torso and butt into the gap by lowering yourself with your arms. Bend your elbows and lower yourself so that your elbows align with your shoulders, pointing straight backward. Straighten your arms to lift yourself back up. Do 3 sets of 10 or so reps. This exercise engages all of your abdominal muscles at once, and no equipment is required. Make it part of every ab workout you do and you'll start seeing a difference. Here's how to do a plank:  Lie on the floor stomach-down, with your legs stretched straight. Lift yourself up onto your forearms. Keep your elbows in a straight line with your shoulders, and point your fingers straight ahead. Lift up onto your tiptoes, so that your legs and torso aren't touching the ground. Keep your back straight. Hold the position for as long as you can - at least a minute. Tighten those ab muscles. Relax on the floor, then repeat. You can do side planks as well, to work out your obliques. Raise yourself up on just one forearm, turn your body sideways, and lift the other arm straight toward the ceiling. Hold the position, then repeat on the other side.
