Many people work hard to get bigger, stronger muscles and become more defined. If you combine stronger, more defined muscles with a lower body-fat percentage, your muscles will appear even more defined or feel harder. Unfortunately, there's not one specific way to increase your muscular strength and definition; it takes a combination of the appropriate diet, lifestyle, and exercise routine. However, with time and patience you can reach your goal of having more defined and strong muscles.

Increasing Muscular Strength

  1. Although much of your muscle strengthening and definition will come with typical weight lifting or resistance exercises, if you want your muscle definition to show or your muscles to feel hard, you'll need to include regular cardio.
    • Cardio exercises are great for a variety of reasons. They help improve your mood and sleep habits, decrease your risk for obesity, diabetes, and high blood pressure, and can even help you have more efficient circulation. [1]
    • In addition to the health benefits, regular cardio is necessary to help your body burn calories and decrease the excess fat that can accumulate both on top of and underneath your muscles. [2] The lower amounts of fat you have or the lower your body-fat percentage is, the more defined and hard your muscles will look and feel.
    • Include at least 150 minutes of moderate-intensity cardio each week. [3] This could include: jogging/running, rowing, dancing, using the elliptical, or doing an aerobics class.
  2. To get the best workout and get the best results, you'll want to do more than one type of exercise per muscle group. [4]
    • Doing a variety of exercises can help ensure you're strengthening and defining your muscles in different ways. Each exercise may work different parts of the muscle group or engage a variety of different smaller muscles. This will help you get the most defined look. [5]
    • For example, do not just do squats to tone your legs. Do a combination of squats, lunges, calf raises, leg raises, and leg curls. Each exercise is unique in which muscles they engage.

  3. Both higher reps and lower rep exercise plans can benefit your muscles in a variety of ways. Include both to get the best workout.
    • If you're doing higher reps with a lower weight, this can help you build bigger muscles. These will show more, be more defined and may feel harder. This is a good thing to keep in mind if your goal is also be to bulk up. [6]
    • However, higher reps with a lower weight doesn't necessarily build strength. It mainly builds muscular bulk. [7]
    • Lower reps with higher weight help you build more strength. The lower repetition amount and higher weights works your muscles differently that results in stronger more powerful muscles. [8]
  4. Rest days are equally as important as days where you work out. Studies have shown that the actual strengthening and size increase happens during rest, not work. [9]
    • It's typically recommended to include at least one to two rest days weekly. However, these should be "active rest days." That means, instead of lounging around all day, do some light intensity or stretching exercises like walking or yoga. [10]
    • In addition to your active rest days, make sure to rest between muscle groups. [11] For example, if you focus on lower body muscles on Monday, use Tuesday to work your upper body instead.

Including Basic Exercises to Define Muscles

  1. [12] Squats are a great basic exercise to help achieve more defined and toned muscles. This move works a variety of muscle groups and can really help you have defined legs and glutes. [13]
    • Choose an appropriate weight on a barbell. Carefully lift the barbell and place it gently on the back of your shoulders right underneath your neck. Squeeze your shoulder blades together so the barbell is resting on your muscles, not on your spine.
    • Stand with your feet slightly wider than hip width apart and toes facing forward. Begin to squat down as if you were sitting back into a chair. Squat until your thighs are almost parallel to the floor.
    • Pause at the bottom for one to two seconds. Slowly push yourself back up to the starting position. Push through your heels and squeeze your glutes. This is one repetition. Repeat as desired.
    • Start with a fairly high weight and do a lower number of repetitions (six to eight) for this exercise. This exercise should feel very intense for you to be building muscle. [14]
  2. Walking lunges are another great exercise that works a variety of leg muscles. In particular, it helps strengthen hips, thighs, and glutes. [15]
    • Stand with your feet shoulder-width apart and place your hands on your hips, or rest them on the back of your neck.
    • Step forward with one leg and drop your back knee down while bending your front knee. Lower your body down until your rear knee almost touches the ground. Make sure your front knee stays over your ankle, not in front of it.
    • Push and pull yourself up back to standing with your front leg. The muscles used should mainly be from your front leg and glutes.
    • Step forward again with the opposite leg. Continue "lunge walking" for eight to 10 reps per leg.

    Use proper form when doing walking lunges. Walking lunges are a great exercise to build leg and abdominal muscles. It's one of the best lunge variations, involving complex motion that works your muscles. Lean forward while performing them to engage your abs properly, or else the exercise will only target your legs. The more parallel you are to the ground, the harder your abs have to work. Try incorporating hand weights or dumbbells to increase your arms, legs, and core strength.

  3. Any variation of the plank exercise will work your entire core. This is one of the exercises that work all muscle groups in your core in addition to your upper body and lower body. [16]
    • Start in a traditional plank position by lying face down on the floor. [17] Support your body weight on your forearms and toes. Keep your body perfectly straight by keeping your core engaged and your hips tucked under.
    • Start by bringing your left knee up towards your left elbow and place your left toes on the floor. Then return your left leg back to the starting position.
    • Repeat on the right side. Repeat this series for 10 reps per side.
  4. Another great exercise that targets your core, bicycle crunches specifically target the front of your abdominal muscles and your obliques (the sides of your abs). [18]
    • Lie on your back on an exercise mat. Place your hands behind your head, bring your knees up in the air so they are bent at a 90 degree angle.
    • Start the crunch by bringing your right knee toward your right elbow. Lift up your shoulders and head off the mat to help you meet your ankle.
    • Alternate sides by switching over to the left leg and left arm.
    • Aim to build up to at least 60 seconds of the crunches. [19]
  5. This is a great movement to work a variety of muscles in your arms, back and shoulder. It's an all-encompassing upper body exercise. [20]
    • Start by choosing a dumbbell or kettlebell of appropriate weight. Hold it in one hand at shoulder height with your palm facing forward.
    • Push and press your hand up in the air until your arm is completely straight (but not locked at the elbow joint). Pause here at the top.
    • Slowly lower your hand back down to shoulder height. Start by doing two reps per arm, then progress to three reps per arm and end with five reps per arm. [21]
  6. Doing an incline bench press helps build mass and strength in the chest and shoulders. [22]
    • Lay down on an incline bench that is set to about 30 or 45 degrees. Place your feet flat on the floor for proper form.
    • Lift an appropriate weighted bar with a grasp width that is about shoulder-width apart. Start with the bar in the air and arms fully extended and locked.
    • Slowly lower down the bar until you are just about an inch or two away from the top of your chin or clavicle bone. Pause for a moment and then push the weight back up to the top position.
    • To build mass and strength with this exercise, choose a weight on the barbell that is heavy enough to bring on complete muscle fatigue after four to six repetitions. [23]

Changing Your Diet to Increase Muscle Strength and Definition

PDF download Download Article
  1. Although you may not be trying to lose weight, it's still a good idea to keep track of your overall calorie intake each day.
    • Know how much you typically eat in one day. If you start to gain or lose unwanted weight, you'll have a starting number to work with.
    • You can keep track of your calories in a food journal or app. In addition, many of the apps have a food journal included.
    • Consider using an online calculator to figure out about how many calories you need each day to maintain your weight with your exercise.
  2. In order for your muscles to look defined or to feel toned and hard, you'll need to lose any excess fat that is stored above or beneath of them. Low-carb diets have been shown to be the best for reducing body fat. [24]
    • In addition to reducing body fat, low-carb diets help you lose weight more quickly compared to other dieting styles (like low calorie diets). [25]
    • Carbs are found in a variety of food groups. Limit foods like grains, starchy vegetables or high sugar fruits. Many of the nutrients found in these foods can be consumed from other food groups.
    • Still include carbohydrate containing foods like dairy and low-sugar fruits. These contain other nutrients that are essential for your health.
    • Include 1 cup servings of low-fat dairy throughout the day. These foods are rich in protein, calcium and Vitamin D. [26]
    • Low-sugar fruits still contain carbohydrates but also contain high amounts of fiber and antioxidants. Try 1/2 cup servings of blackberries, strawberries, raspberries and cranberries. [27]
  3. [28] Protein is essential to your health, but also plays an important role in your diet when you're exercising and trying to build and tone your muscle mass.
    • Aim to have one to two servings of lean protein at each meal. Including a 3 – 4-oz portion can help you reach your daily recommended amount. [29]
    • If you want to find out exactly how much protein you should be eating daily, there's a simple equation to follow: Weight in kg x 0.8-1.0 g of protein. [30] The harder your workouts or longer you're active, the more protein you'll need. For example, if you weighed 150 pounds, the equation would be: 150 / 2.2 = 68.1 kg. Take 68.1 x 0.8-1.0 = 54-68 g of protein daily.
    • Most people do not need large quantities of protein daily. Only athletes, power lifters, and bodybuilders need larger quantities of protein daily. In addition, large quantities of protein over a long period of time can cause kidney damage. [31]
    • Choose leaner protein sources like: eggs, poultry, low-fat dairy, seafood, lean beef, pork, and tofu.
  4. To make your meals more balanced, you'll need to eat more than just protein based foods. Include a large quantity of low-sugar fruits and non-starchy vegetables to help balance your meal.
    • Health professionals typically recommend consuming about 5-9 servings of fruits and vegetables daily. [32] If you're following a lower carb diet, you might want to emphasize the non-starchy vegetables more.
    • Include a serving or two of non-starchy vegetables or leafy greens at most meals. This is generally about 1 cup or 2 cups of the leafy greens. [33]
    • Stick to fewer servings of those low-sugar fruits and keep portions at a 1/2 cup. [34]
  5. When you're trying to build muscle mass and strengthen or define muscles, you'll need to snack or eat in a way that helps fuel your body through a workout and help you recover afterwards.
    • Not fueling or recovering appropriately can leave you feeling more tired, fatigued and cause poor performance down the road. [35]
    • Eating a pre-workout snack can help give your body the energy it needs to actually perform your workout. It should be mostly simple and nutritious carbohydrates so they can digest easily and give your body the energy it needs readily.
    • Ideas for pre-workout snacks include: a piece of fruit, a whole grain waffle with a little peanut butter or a bowl of oatmeal.
    • Post workout snacks need higher amounts of protein, but also need carbs too. You need to replace the energy spent during your workout and give protein to help repair the muscle tissue.
    • Great post workout snacks include: protein shake, trail mix, chocolate milk or your next meal (if it is within an hour).

Including Supplements

PDF download Download Article
  1. You may want to consider including some protein shakes in your daily meal plan. Some studies have shown that 100% whey shakes can help you lose weight, increase muscle mass easier and increase strength. [36]
    • Whey protein is a derivative of milk. It contains all the essential amino acids your body cannot make itself. Since it's a complete protein, it's a high quality protein to use.
    • You can use your protein shake as a snack or use it to fuel or recover from a workout. Remember, try to stay within your protein goal for the day. More is not always better.
    • Other options for protein shakes include egg white protein, pea protein, or hemp protein. You can find protein powders specifically made for women or people with dietary restrictions, such as vegans.
  2. Creatine is a fairly common supplement used by many athletes and people looking to improve their performance. Some studies have shown that there are some benefits to using creatine if you want to increase muscle strength and performance. [37]
    • Creatine is made naturally in the body by the liver. It's transported in the blood to help supply energy to all cells. However, most creatine is used and stored by your skeletal muscles. [38]
    • Creatine may help you build more strength and muscle bulk because it provides you with additional energy to do more repetitions and higher weights. [39]
    • You should always talk to your doctor prior to starting any supplements (as they are not regulated by the FDA). Ask if it would be safe and appropriate for you.
    • Discontinue use if you feel any of the following symptoms: nausea, cramping, diarrhea or stomach pains.
  3. Having a cup of coffee before a workout is another option that's a natural way of boosting your performance.
    • Studies show that when you drink coffee prior to a workout you can train longer and use a higher weight. In addition, if you're doing cardio, you can finish more quickly. [40]
    • It's typically recommended to drink 1 6-8 oz cup of coffee prior to your workout. This contains about 80-100 mg of caffeine which is all you need before you hit the gym. Do not try caffeine pills or other supplements as these may come with adverse health effects.

    Top Answerer
    Lower your body fat for definition (i.e. "to make your abs show") by doing cardio like running, swimming, jogging, etc. Then incorporate abdominal exercises into your routine: planks, push-ups and sit-ups all work the core abdominal muscles.

      About This Article

      Article Summary X

      To get hard muscles, start by incorporating a variety of exercises into your routine for each muscle group, such as squats, lunges, and leg curls to tone your legs. When lifting weights, do fewer repetitions with heavier weights to get more powerful muscles. Additionally, include 1 to 2 days per week where you only do light exercises like stretching, since your muscles actually grow and strengthen while you’re resting. You should also fill up on healthy proteins, like lean meat and low-fat dairy, to increase your muscle mass. For advice from our Fitness reviewer on how to use supplements and protein shakes to help you build muscle, read on!
