Weight trainers do not use as much glucose fuel as higher intensity or longer duration aerobic sports like track and endurance running and cycling. But even so, it pays to keep those glycogen stores topped up if you want to be at your best in training. Low numbers of repetitions with heavy weights develop strength, whereas lighter weights and more repetitions build muscle size and endurance. The latter is likely to expend more energy.
One aspect many new bodybuilders look into is protein shakes. These are a quick and convenient way to take in more protein and calories, but they aren't necessary. If you have a hectic lifestyle and can't always make time to eat a meal, a shake may be useful. But otherwise, you should be able to get all your protein and calories from whole foods. When pushed for time, trainer Nate Green recommends a simple, healthy, high-calorie shake consisting of almond milk, bananas, whey protein powder, coconut and a greens supplement. Have one or two of these per day if you can't fit in solid meals. Adjust meal serving sizes to fit your calorie needs and aim to split these calories among three meals plus a couple of snacks. Should you find you're struggling to hit your calorie goal, add in more calorie-dense foods such as nuts, nut butters, dried fruit, whole milk and olive oil.
Reverse crunch: Lie flat on the floor with your lower back pressed to the ground. Put your hands beside your head or extend them out flat to your sides—whatever feels most comfortable. Crossing your feet at the ankles, lift your feet off the ground to the point where your knees create a 90-degree angle. Once in this position, press your lower back on the floor as you contract your abdominal muscles. Your hips will slightly rotate, and your legs will reach toward the ceiling with each contraction. Exhale as you contract, and inhale as you return to the starting position.
Here's one for those of you who still compete. One of the most important things about professional bodybuilding is the way you present all that hard work and sacrifice when you get on stage. You want to pose in a way that hides your flaws and accentuates your strengths. If you want to see those flaws and strengths clearly, take pictures of your poses and when you look at them, cover your face. Sounds silly but it allows you to be more objective. Now, you may want to enlist the help of a credible posing coach to hone in your routine.
