How to Define Muscles

You may have strength and endurance, but you don't feel your body shows it. You want 6-pack abs and arms that are cut and toned. This kind of physique requires a targeted workout, combined with a high-protein diet that fuels muscle development. If you want to sculpt a new shape, keep up a fat-burning, strength-building routine to define your muscles and ditch any empty calories that are causing fat to cover your ripped physique. You'll notice a difference in as little as 8 weeks. [1]

Things You Should Know

To define your muscles, eat a high-protein diet and do both cardio and strength training. According to certified personal trainer Danny Gordon , protein helps you build muscle when strength training, and "cardio is important because you need to be able to burn those extra calories" to see muscle definition.

Burning Fat

  1. With Tabata training, aerobics, or a fitness boot camp, you push your body to maximum speed for 1 to 4 minutes and then rest for 1 to 4 minutes. HIIT workouts increase your metabolic rate, which will cause your body to burn fat more quickly. [2] [3]
    • If you have limited time to work out, Tabata may give you the best bang for your buck. These high-intensity workouts can vastly improve your cardiovascular strength and maintain overall fitness in as little as 10 minutes a day.
    • However, these are advanced workouts that you shouldn't attempt if you are a beginner, and they may not do much in terms of specifically increasing your muscle tone and definition.
    • Boot camp workouts use simple moves and often are designed for beginner- and intermediate-level exercisers.
    • You typically can find boot camps or other HIIT training programs at your local gym or fitness center.
  2. [4] Most bodies use carbohydrate stores exclusively for the first 15 to 20 minutes of moderate-intensity exercise. If you keep going after that point, your body will start burning fat. [5]
    • Aerobic activity for at least 40 minutes at moderate to vigorous intensity has the added benefit of lowering your blood pressure and cholesterol, in addition to overall cardiovascular health benefits.
    • Not only will you have lower body fat and more defined muscles, but you'll also be at lesser risk for heart attack or stroke.
    • Good fat-burning cardio exercise can be as simple as jogging on the treadmill (or outside, if the weather's nice). If you need more variety, check out aerobics classes at your local gym or fitness center.

  3. While strength training builds muscle, cardio sessions focus on burning fat. Using cardio and strength training together is the best way to achieve maximum muscle tone and definition. [6]
    • How you combine your cardio and strength training will depend on your needs and your schedule.
    • For example, it might be easier for you to get your cardio in by going for a run early in the morning, and then doing your strength training after work.
    • Another option is to plan your training sessions for an hour, and alternate between cardio and strength training in 15-minute intervals.
  4. Consider doing 45 to 60 minutes instead of 30 minutes to lose more fat and define your muscles; however, overtraining can be very hard on your body, so take 1 to 2 days of rest each week. [7]
    • Doubling up on your cardio ensures that you're still exercising for the same amount of time and at the same hours each day.
    • You might also consider doing yoga on your off days to replace your regular weight training. While yoga will work your muscles, it's generally not considered as intense as weight training, so a light routine would be appropriate for your rest days.

Building Strength

  1. You won't build muscle definition if you only strength train for 15 or 20 minutes once or twice a week. To get the tone you want, you must make a commitment to hit the gym on a more frequent basis. [8]
    • Build a strength-training routine of moderate- to vigorous-intensity, depending on your level of experience.
    • You can do the research and set up a routine on your own, but the easiest way to create your routine is to schedule a session with a certified personal trainer. They can not only advise you on exercises to do that will meet your goals, but also critique your form and technique.
    • Typically, you'll get best results by focusing on your upper body the first day, your lower body the second day, and your core the third day.
    • If you're strength training on a four day rotation, split your core over each of the 4 days and do 2 upper-body days and 2 lower-body days.
  2. If you are doing your exercises correctly, you will tear a lot of muscle fibers. Your body needs time to repair your muscles and rebuild them so they are stronger. [9]
    • Allow enough time for rest by rotating the muscle groups you work each day. For example, you might do upper body 1 day, lower body the next day,
    • You typically can do core strengthening exercises with only 24 hours of rest before the next strength-training session.
    • Adequate rest also means getting adequate sleep . Your body is rebuilding muscle while you sleep, so make sure you get between 7 and 9 hours of restful sleep each night.
  3. You should be strength training with a weight heavy enough that you can only complete an exercise with correct form for 12 to 15 repetitions. The argument used to be that you used heavier weights to gain mass and did higher repetitions with lighter weights for tone and definition; however, modern training suggests there is a happy medium. [10]
    • This plan can work well if you only have fewer days per week that you can devote to strength training.
    • Combining bulk or power training with high-rep strength training also can work well to get you the definition you want.
    • For example, you might do a heavy, power upper-body strength training session on day one. The next day, do a similarly heavy lower-body strength training session.
    • Take a day off, then do an upper-body strength training session with lower weights at higher repetitions. Follow up the next day with a similar lower-body session.
  4. Move slowly through the pushing and pulling motions, emphasizing quality over quantity. Especially if you're just starting, don't worry about how many reps you can do. Instead, make sure you have solid, consistent technique. [11]
    • To control your movement correctly, you should lower or release the weight on each repetition at roughly the same speed you raised it. Think in terms of actively lowering (or pulling back) the weight, not simply dropping it.
    • Get a personal trainer or an experienced weight lifter to check and critique your form.
    • Keep in mind that poor technique and sloppy form doesn't just mean your training is less effective, it also puts you at risk for injury.
  5. Organize your strength-training routine so that you're doing 3 or 4 sets of 12 to 15 repetitions of each exercise. Rest for 30 seconds to 1 minute between each superset. [12]
    • For example, you might do presses and then follow up with lifts.
    • When you alternate between pushing and pulling motions, you work different parts of the muscle.
    • This gives the portion of the muscle you previously worked a little extra time to recover, so you can take a shorter rest break between sets.
  6. When you push your muscles to the max you stimulate hypertrophy, which increases the volume of your muscles. This not only builds muscle mass, but also will improve their definition. [13]
    • For example, 3 sets of bicep curls, flies and push ups should leave your arms shaking. If they don't, you need to add more weight.
    • Make sure you're doing simple exercises, such as pushups or dumbbell presses, that you can control and complete in good form even when your muscles are exhausted.
  7. Don't work your biceps without working your triceps, shoulders, back, and chest. You won't achieve good resting definition unless your whole body is being worked hard.
    • Ignoring surrounding muscles in favor of the major ones, such as biceps, can lead to muscle imbalances that will significantly increase your risk for injury.
    • Aim to work an entire muscle group with each exercise. If you don't know a lot of different exercises, sign up for a few sessions with a personal trainer. They can help you create a well-rounded workout.
    • Don't just work the muscles you see in the mirror. You may not think about working out your back because you can't see it, but remember that everyone else can!
    • For example, squats are a compound exercise that target several muscles in the lower body and core, including your quads, glutes, and core. You can even add light weights to your squat to further work these muscle groups.
    • Reader Poll: We asked 141 wikiHow readers and 63% of them agreed that the best exercise for defining your muscles is doing squats with added weight . [Take Poll]

Changing Your Diet

  1. Trainers often say “abs are made in the kitchen.” Muscle definition requires a body fat percentage below 10 percent, which is almost entirely based on what you eat. Generally, you should eat more protein and lay off foods that are high in fat and simple carbohydrates. [14] [15]
    • If you're already a relatively skinny person, you still need to limit your carbs while working on a strength-training program that emphasizes building bulk muscle mass.
    • Instead of eating 3 big meals a day, try to eat 5 or 6 smaller meals, so that you're eating once every 2 to 3 hours.
    • Plan your meals so that 40 percent of your calories are coming from protein, while you limit fats and carbohydrates to 30 percent each. [16]
    • At least 85 percent of the carbohydrates you eat should come from vegetables, with the rest coming from complex carbohydrates such as fruits, whole grains, nuts, and seeds.
  2. Protein helps rebuild muscle and will help ensure a faster recovery. Try a protein shake, an apple with peanut butter, chicken, nuts, Greek yogurt or cottage cheese. [17]
    • Ideally, you want to have your snack 30 to 45 minutes before you start your workout.
    • Whole food typically works better for your pre-workout snack. A protein shake may work better post-workout, especially if you find it difficult to eat after an intense workout.
    • Whey protein is one of the best sources of complete protein, because it includes all the essential amino acids you need to rebuild your muscles.
    • You can buy whey protein in powder form and blend it into shakes yourself, or you can buy pre-made protein shakes at grocery or health food stores.
  3. Quinoa, spelt, oat bran, amaranth, and other ancient grains are high in protein and minerals, which may help to promote muscle growth by supplying your body with the necessary nutrition. [18]
    • Many of these grains can be mixed into salads or sides, or included in a breakfast bowl.
    • You also can find bread made from these grains at organic or natural grocery stores.
  4. Dehydration decreases your performance and can put you at risk for injury, as well as make recovery more difficult. While strength training, you shouldn't lose more than 2 percent of your body weight in fluid. [19]
    • To get an idea of how much fluid you lose during your workout, weigh yourself before and immediately after your training session. The difference between the 2 weights is the amount of fluid you've lost.
    • For each pound of fluid you lose, you must drink between 20 to 24 fluid ounces (590 to 710 mL) of water to replace it.
    • Replacement of lost water is sufficient to keep you hydrated provided you were hydrated to begin with. To determine this for certain, check your urine. If it's clear, you're well hydrated.
    Gunnar Peterson, Celebrity Personal Trainer

    Hydrate well to prepare your muscles for exercise. "Hydration is everything. Think of this: your muscles are 70-plus percent water - how are you not drinking water during a workout?"

      Tips

      • Judge how your muscles begin to contract while resting. When your muscles feel harder, you will begin to get definition. As you burn fat, the muscles will start to look sculpted.

      • Stretching muscles prevents skeletal misalignments that can wreck your posture, so be sure to include at least the big muscle stretches a couple of times a week, after exercise.

      About This Article

      Article Summary X

      If you want to define your muscles, you’ll need to keep up a high-intensity workout routine and eat a diet high in proteins. Try to perform cardio exercises, like running or cycling, for at least 30 minutes 5 times a week to burn fat, which you need to do to develop defined muscles. Add regular cardio exercises, such as running or swimming, 5 times a week. You should also perform moderate-intensity strength exercises for at least 30 minutes 3 to 4 times a week, which will build muscle. After each workout, eat a high protein snack, such as an apple and peanut butter, or chicken, which will help rejuvenate your muscles. For your overall diet, eat 5 to 6 small meals a day consisting mainly of proteins, which will help your body build muscle and reduce fat.
