Assuming that around 80-90% of your diet is comprised of nutrient-dense, “clean” foods (such as lean proteins, minimally refined carbohydrates and healthy fats), the other 10-20% can come from whatever sources you’d like as long as it fits into your overall daily calorie and macronutrient totals. (The only exception here are for foods that contain partially hydrogenated oils, as these should be strictly limited or eliminated altogether)
Most bodybuilders become familiar with their kitchens as a matter of necessity. Whether you can quickly master taste or not, cooking your own food means you know everything going into it. During a cut, where excess salt or sugar in ready meals and takeaways can hinder weight loss, bringing your own food to work will eliminate any risky meal choices.
As an example, let's say someone's goal is to go to the gym three days per week before work. A basic cue would be to place their gym clothes, post-training shake, and shoes next to their bed the night prior so those items are the first thing the person sees—or maybe trips over—when they wake up. The theory is that the cues will create a routine, and eventually, the person won't need the cue.
One scary-sounding study says your health depends on x, but another says it depends on not doing x. One writer says CrossFit kills people, but the people in those pictures all seem ripped and happy. But so does that woman in yoga class. And, let's be honest, so does the Shake Weight guy! So does that online writer guy shouting at you about intermittent fasting, high reps, low reps, high-carb, low-carb, no-carb, steady-state, or HIIT.
Once you feel comfortably balanced, contract your quadriceps and gluteal muscles and lower your body slowly. When you reach the point where your upper legs are just below parallel to the floor, push back up to the top without “locking out” and repeat the movement. Make sure to keep your abdominal muscles tight to protect your lower back, and keep your head up and your eyes fixed ahead as you perform this exercise.
Prepare for the long haul. It's important to know that you're not going to start doing deadlifts one day and wake up the next day bulked up like the Hulkster. Bodybuilding takes a long time for you to see the kind of results you're hoping for, but with the proper time and dedication, you will start seeing those results. This isn't a field for weekenders who love action movies, it's a 24-7 lifestyle. Think you got what it takes? Get training.
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.
