How To Bulk – Bulking Workout And Nutrition Plan, Per Experts

If you follow fitness coaches and trainers on social media, odds are your feed is full of women killing it in the gym. From videos of them crushing P.R.s on hip thrusts and deadlifts to posts about their favorite post-workout protein shake or daily creatine, you can tell they have a plan.

Wondering how they do it? Well, there’s a solid chance it’s bulking. And all it means is putting on major muscle, per Laura Girard, NASM-CPT. It’s a term central to certain sport communities, like bodybuilding, Olympic weightlifting, and powerlifting, she adds. Luckily, it doesn’t look like it’s staying in those realms. In fact, the hashtag #bulking alone has over 2.1 billion views on TikTok. (Yes, with a B.)

“We should all want to bulk,” Girard says. “Building muscle is necessary if your goals are strength or general fitness. It’s one of the best investments we can make in terms of our long-term health.”

Making serious muscle gains is hard work, and it doesn’t happen by accident or overnight. “Contrary to popular belief, it’s actually very hard to gain a lot of muscle mass,” says Asia Johnson, CPT, a Washington, D.C.-based certified personal trainer.

Bulking requires careful consideration in the weight room and the kitchen. Here, experts explain what bulking is, how to bulk effectively and safely, and whether it’s right for you (and, that key muscle-building tweak you’re probably missing in your routine!).

What is bulking?

If you’ve never tried to bulk, you might be scratching your head about what it is to begin with. In short, bulking is gaining muscle mass and size from a combination of increased calorie intake and strength training, says Johnson. And FYI, anyone can bulk up. Whether you’re a competitive athlete or just someone looking to build muscles and increase muscle definition, there are benefits for you. (More on that in a sec.)

How Bulking Works

Bulking consists of two parts: resistance training and fueling—both done in abundance, says Jason Machowsky, CSCS, exercise physiologist, and board-certified sports dietitian.

“First, you need a stimulus for muscular development, which is usually resistance or strength training,” Machowsky says. “Bulking then involves eating adequate protein, extra carbohydrates, and extra calories to provide your body with the additional fuel required to build more muscle via protein synthesis. The protein is the ‘building blocks’ and the extra calories and carbs are the fuel your body needs to use to do the building.”

So, what protein synthesis boils down to: Consume enough calories to stay energized during workouts and take in enough protein to fuel muscle growth.

“Our bodies are constantly breaking down proteins into amino acids to build up tissues in the body,” Girard adds. “The breaking down (catabolic) and building up (anabolic) processes are always happening at the same time, so if we want to build muscle, we want to perform activities that support the anabolic process, like resistance training, eating enough, and getting adequate sleep.”

Muscle growth takes place during recovery periods (so, going hard in the gym and eating won’t necessarily fuel the bulk alone), per Girard. And, surprise, surprise: Much of that recovery takes place during sleep. Exercisers who receive fewer than six hours of sleep per night have less strength than those who get seven or more hours of sleep nightly, per a 2017 Chinese study from the Journal of Musculoskeletal and Neuronal Interactions. (Ding ding ding!)

How long does it take to bulk up?

How long it takes for a person to bulk up (in other words, see muscle growth) is largely dependent on how fast their metabolism is and how many extra calories and grams of protein they’re adding to their diet, per Machowsky.

If you train hard and consume foods carefully, seeing weight gain in lean muscle mass of o.5 to 1 pound per week is ideal, he notes. “People should start to notice some changes within four to six weeks,” Machowsky says.

There are a lot of variables in the mix beyond training and fueling that can impact timing. Keep in mind that muscle growth is based on a wide swath of factors, including your age, hormone levels, and metabolism. And, in addition to a person’s genetics, certain health conditions and hormonal disorders have been found to affect a person’s metabolism. (So, don’t think of the timeframe above as set in stone.)

That said, beginners should expect to see muscle growth faster than, a seasoned bodybuilder or longtime weight room regular, Girard notes. “You’ll see this referred to as ‘newbie gains,’” she adds. “They tend to taper off after about a year of training. The more advanced you become, the longer it will take to gain noticeable amounts of muscle.”

Is there an ideal length for a bulking period? Unless you’re a competitive athlete, there’s not really a must-adhere to timeline, says Machowsky. “Most training phases last six to 12 weeks, though there’s no hard and fast rule about how long you need to spend bulking,” he says.

Bodybuilders often bulk during their off-seasons from competing, as the sport requires them to have very little body fat at the time of a competition. For everyone else, you’re free to schedule your bulking when it works for you!

Bulking For Beginners: 10 Ways To Bulk Up Fast

1. Follow a plan: “If you don’t have a plan, you plan to fail,” says Johnson. “You need to have a plan so that you know exactly what you’re doing.” That clarity will help you stay consistent, less likely to get discouraged, and closer to hitting that goal. (Keep scrolling for a plan to try.)

    2. Find your baseline weight and gradually increase: If you want to bulk up, progressive overload will help you slowly ramp things up. To do this, start lifting with a baseline weight that isn’t too easy but also not super challenging. Then, each week you should increase the weight and decrease your reps, advises Johnson. (More details in the workout plan below.)

    3. Eat a balanced diet: You likely need to eat more calories than you’re used to in order to support new muscle growth and energize your workouts. Eating more protein, especially, will help grow and repair your muscles, says Johnson. (See all the bulking nutrition deets below.)

    4. Stay consistent: When it comes to your workout plan, staying disciplined will get you the results you’re looking for. Johnson notes that building muscle has to be done with intention, and you need to hold yourself accountable to make progress.

    5. Avoid too much cardio: Too much cardio can hinder your muscle growth. “You definitely don’t want to focus on cardio, but you also don’t want to neglect it,” says Johnson. For example, hopping on the stair master or sled pushes for 10 to 15 minutes at the end of your workout is a good way to add in the heart-healthy movement.

    6. Honor your rest days: If you feel inclined to skip your rest days, just know that you could be holding yourself back from gains. “Your muscles break down during your workouts and repair themselves while you’re sleeping and between sessions,” says Johnson. “So if you’re not getting rest, you’re hindering your growth.”

    7. Stay hydrated: This one might go without saying, but hydrating properly will help replenish your muscles. “I always recommend drinking half your body weight in ounces of water,” says Johnson.

    8. Mind your technique: Since you’ll be increasing your weights over time, you also want to make sure that you can maintain your technique. Staying in control of your form will help you avoid injuries.

    9. Track your progress: You can do this by recording on how heavy your weights are, taking pictures and measurements, or noting how your clothes fit each week.

    10. Be patient: The hard truth is there is no quick trick to bulk up. With a little bit of patience, you’ll have an easier time setting realistic goals and expectations for yourself, says Johnson.

    Who Should Bulk—And How To Measure Success

    Putting on muscle mass is in everyone’s best interest, experts agree. Asking yourself why you’re wanting to bulk in the first place is important, though, says Machowsky. That’s what helps you determine success and progress along the way.

    Key questions to ask yourself are: “Is it [for] strength in the weight room? Sports performance? Physique? Overall health?” he recommends. “I would suggest choosing two to three markers of success independent of weight.” Then, focus on those when you’re looking for results.

    For example, he notes that a marker of success might be the weight you’re able to lift during your bulking period, your speed or sport performance, or your body composition (i.e. what a tape measure will tell you as opposed to a scale). Sticking to one, or multiple, measurements can help you track success.

    That said, if your goal is to compete or train specifically for a sport like bodybuilding where you need to lose the “bulk weight” quickly, enlisting the help of a certified sports nutritionist and trainer is crucial. Putting on muscle mass is typically safe for everyone, but quickly shedding weight (or cutting) after a period of muscle mass gain can be dangerous without expert guidance.

    Bulking Nutrition Plan

    Now that you understand the science of building muscles, you know it takes serious fuel. And, you’ll likely need to adjust your diet to during your bulk. “You should be consuming more calories than you are burning in order to put on mass,” says Katie Valdes, RD, assistant director for sports nutrition at the University of Southern California’s Department of Athletics.

    Here’s how she recommends you plan your caloric and protein intake during your bulking period:

    • Aim for a 300- to 400-calorie surplus above your regular calorie consumption. It might be helpful to track how much you’re eating, on average, per week before starting a bulk, then add onto that.
    • Aim for macros of 25 percent protein, 25 percent fat, and 50 percent carbohydrates. That said, “it is very important to emphasize that muscle gains will not occur without being in a calorie surplus even if correct macros are being met,” Valdes points out. Apps like MyFitnessPal and My Macros+ are great tools to track nutrients in foods and how much you’re consuming.
    • Consume at least 1.2 to 2 grams of protein per day per kilogram of bodyweight. “For example, a 150-pound athlete would weigh 68.2 kilograms and have protein goals ranging from 80 to 135 grams per day,” Valdes says. During bulking and aiming for adding lean muscle, you’d want to shoot for the high end of the range.
    • Space out protein intake throughout the day. “Athletes should space out protein throughout the day with each meal or snack containing around 20 to 40 grams of protein,” Valdes recommends. Consuming large amounts of protein at once can often lead to stomach discomfort.
    • Eat protein within 30 minutes of strength training. “Protein should be emphasized within 30 minutes post training and should be paired with a carbohydrate in a 3:1 ratio of carbohydrates to protein in order to optimize muscle synthesis and recovery.” She recommends a food like chocolate milk with 30 grams of carbohydrates and 10 grams of protein.
    • Nibble on a quick (but protein-packed) snack before bedtime. “Another way to meet protein goals could be consuming 25 to 40 grams of protein before bed to stimulate repair of tissue as opposed to tissue breakdown during sleep,” Valdes says. “Some evening snack examples could be hard boiled eggs, cottage cheese, greek yogurt, or a protein shake.”

    Pro tip: Don’t feel as though you need a diet overhaul during a bulk—just continuously feed yourself foods and snacks throughout the day that are high in carbohydrates and protein.

    Supplements For Bulking

    Eating enough calories can be a challenge when putting on muscle mass, Valdes notes, so try to aim for simple foods that contain both ample amounts of carbohydrates and protein. A few of her favorites: deli sandwiches, chocolate milk, protein bars, and peanut butter and jelly sandwiches.

    If you’re still struggling to hit your nutrition targets, you might beeline for the supplements aisle. However, Valdes urges exercisers to proceed with caution. “We want to prioritize a food-first approach, as supplements are not a replacement for eating whole foods,” she says. “Supplements should only be considered if energy needs are being met as well as proper nutrient timing is utilized.”

    Protein powder (preferably one with a 3:1 ratio of carbs to protein) and creatine are both supplements that can help facilitate muscle growth, per Valdes. Again, they don’t necessarily spur muscle growth necessarily any better than whole foods could—it might just make hitting your macros easier to do.)

    Bulking Workout Routine

    The other key component of bulking is strength training. Here, Machowsky walks through his top tips for anyone on a bulk (a.k.a. simply wanting to add muscle mass):

    • Train the major muscle groups (chest, back, legs, arms, shoulders, core) at least three to four times per week. “These can either be done as full-body workouts or as splits,” he says. “If you’re doing splits, you’ll likely be lifting four days per week to get all of the muscles versus full-body sessions that can be done in three days.” (FYI: Splits are training sessions divided into both upper- and lower-body moves, or both push exercises and pull exercises.)
    • Complete 10 working sets per muscle group per week (split up into different sessions) with eight to 15 reps per set. “You can do higher and lower rep sets as long as you go to reasonable amounts of fatigue,” Machowsky says.
    • Transition from heavier to lighter loads over time or alternate between rep count. This variation can offset overtraining syndrome, per studies in the International Journal of Sports Physical Therapy.
    • Prioritize heavy compound lifts. These include squats, deadlifts, and bench presses.
    • Pepper in other basic, but impactful, strength exercises. Moves like push-ups, dumbbell rows, overhead presses, lunges and/or step-ups, core work (like planks), biceps curls, and triceps dips are all on Machowsky’s list. (In other words, don’t feel like you need to reinvent the wheel at the gym to see gains.)
    • Give yourself time to rest. Don’t neglect recovery when it comes to adding muscle mass. “Rest between 24 to 48 hours when working the same muscle group,” Girard says. “We want to focus on creating controlled muscular fatigue to get those adaptations while minimizing systemic fatigue, or that full-body tired you get after a particularly hard session.”

    What To Do After Bulking

    Give yourself a pat on that very strong back, you did it! But, this can be just the beginning. Muscle growth can (and should) be a continuous journey, so long as you fuel yourself adequately. Try not to stop training entirely following a bulk, says Machowsky. “It’s a bit easier to maintain your gains than to build new mass, so you could reduce your overall training volume a bit [following a bulking period] if you need a break, but don’t stop all together.”

    If you reduce the intensity of your training, yet continue to eat the same number of calories that fueled your bulk, it could lead to unintended weight gain, says Machowsky. He says you can fix that by reverting the number of calories you were consuming prior to the bulk.

    Keep in mind that cycles of bulking and cutting can potentially be harmful if you’re not a high-level athlete, per Girard. “We can all benefit from building muscle, and we should consider the many risk factors associated with weight cycling,” she says. “Hyper-focus on numbers can lead to a host of health problems, both mental and physical.”

    Bottom line: Everyone can benefit from bulking, or gaining muscle. The basics of a bulk include consuming enough protein and calories and hitting the strength room hard along with recovering with ample sleep.
