Nudge theory is the idea that a gentle push in the right direction can help people make positive changes in their lives. This theory has been applied to public health policies to promote healthy behaviours, such as increasing physical activity and improving dietary habits. Similarly, exercise nudges are simple interventions that can motivate people to be more physically active and lead to positive lifestyle changes. For example, a study by Dr Abby King at Stanford University found that small amounts of social support can significantly increase physical activity levels. In addition to exercise, building muscle also depends on various factors such as age, sex, genetics, diet, and rest. Resistance and strength training are particularly effective in growing and defining muscles.

What You'll Learn
Resistance training
There are many ways to incorporate resistance training into your fitness routine. This includes using free weights such as dumbbells, barbells, and kettlebells, as well as weight machines, resistance bands, and your own body weight. Bodyweight resistance training includes exercises like push-ups, squats, and pull-ups, which can be just as challenging as using weights.
It is recommended that beginners train two to three times per week to gain maximum benefit. It is also important to rest each muscle group for at least 48 hours between workouts to maximise gains in strength and size. Additionally, varying your workouts and the number of repetitions, exercises, and weights used can help you push past a training plateau and maintain your strength gains.

Cardiovascular exercise
There are many simple cardio exercises that can be done at home, such as marching in place, jogging in place, jumping jacks, and air squats. Marching in place can be done by starting with your feet together and lifting one leg 3-6 inches off the floor. Hold this position for 10-15 seconds, return your foot to the floor, and repeat with the other leg. To increase the intensity, you can march faster or lift your knees higher. Similarly, jogging in place is an effective way to increase your heart rate and can be done as a warm-up activity. Jumping jacks are another simple and beginner-friendly cardiovascular exercise that can be performed almost anywhere.
For those looking for more intense cardio exercises, high-intensity interval training (HIIT) is a popular choice. HIIT involves short bursts of intense activity followed by brief rest periods, aiming to get your heart rate up to near maximum levels. This style of training is very efficient and versatile, allowing you to use different methods, exercises, and equipment to build muscle and burn fat. An example of a HIIT workout is the 4x4 routine, which involves exercising at maximum intensity for four minutes, followed by three minutes of recovery, repeated for four cycles.
In addition to HIIT, there are other cardio exercises that can be done to build muscle and improve cardiovascular health. Walking lunges, for example, are a great blend of strength training and cardio, targeting leg muscles and improving lower body strength. Sled pushes, pulls, and drags are another way to pile on muscle and cut fat, as they target different parts of the body depending on whether you're pushing or pulling the sled.
It's important to note that the key to a successful exercise routine is staying interested and motivated. Varying the types and intensity of exercises, as well as incorporating rest days, can help prevent overuse injuries and keep you engaged. Additionally, it's recommended to consult a qualified trainer or health professional to set a target heart rate range to ensure you're working out at the right level.

Diet
To nudge muscle growth, it is important to focus on a diet that is rich in nutrients and supports muscle gain. Here are some dietary strategies to help you do that:
Firstly, ensure you are consuming enough calories. Muscle growth requires a positive energy balance, so you need to eat more calories than you burn. This doesn't mean resorting to empty-calorie foods like soft drinks and chips, which are not conducive to building muscle. Instead, focus on nutrient-dense foods that provide your body with the fuel it needs to build muscle. This includes foods like fruits, vegetables, lean proteins, and low-fat dairy products.
Secondly, prioritize protein sources in your diet. Protein is essential for muscle growth and repair, but this doesn't mean you should adopt a high-protein diet. Instead, aim for a balanced approach, ensuring you get enough protein while also meeting your body's needs for other macronutrients. The recommendation is to consume 1.2–2.0 grams of protein per kilogram of body weight per day. For example, a 150-pound person should aim for around 81–137 grams of protein per day. Remember that individual needs may vary based on activity levels, goals, and medical history, so consult with a specialist to determine your optimal protein intake.
Thirdly, don't forget about healthy carbohydrates and fats. While protein is crucial, carbohydrates provide the energy needed to fuel your workouts, and healthy fats are essential for overall health. Include a variety of whole grains, fruits, and healthy fats like avocado, nuts, and olive oil in your diet.
Additionally, consider using supplements strategically. If you struggle to get enough protein from food alone, protein shakes and powders can help. Rice protein supplements, for example, have been shown to be effective for muscle gain during weight training.
Finally, stay hydrated. Drinking plenty of water is important for overall health and can also help with muscle growth and recovery.
Remember, the key to nudging muscle growth through diet is to focus on nutrient-dense, whole foods while ensuring you're consuming enough calories to support muscle growth. This, combined with a strategic exercise plan, will help you achieve your muscle-building goals.

Sleep
Additionally, sleep is when the body replenishes glycogen, the fuel source for muscles. Working out depletes this fuel source, so getting enough sleep is crucial for recovery and replenishing energy. A study from Brazil divided participants into two groups, allowing one group only 5.5 hours of sleep and the other 8.5 hours. The group with less sleep had 60% less muscle mass, while the second group had 40% more.
To maximise muscle growth, it is recommended to get 7-9 hours of high-quality sleep each night. This involves reaching the N3 stage of non-rapid eye movement (NREM) sleep, where the body's most physically restorative processes occur. During this stage, blood flow to the muscles increases, promoting tissue growth and repair.
Practicing good sleep hygiene is essential for achieving quality sleep. This includes maintaining a regular sleep schedule, giving your screens a rest before bed, and creating a comfortable environment. Progressive muscle relaxation is another technique that can help relax the body and quiet a racing mind before sleep.

Massage
There are different types of massages, each with its own benefits. A Swedish massage, for example, is a gentle full-body massage that helps release muscle knots and is perfect for relaxation. Deep tissue massage, on the other hand, uses slow strokes and deep finger pressure to relieve tension from deep muscle layers. It is a good option for those with muscle problems. A sports massage is ideal for athletes with repetitive use injuries, and a prenatal massage can help reduce body aches and stress during pregnancy.
When giving a full-body massage, it is important to create a comfortable environment. The room should be private and warm, and the person receiving the massage should be mostly undressed, although they may choose to wear underwear.
The massage can start with the neck and shoulders, using thumbs to knead deep into the muscles. Then, move to the back, arms, legs, and feet, using long, relaxing strokes. To work out knots, use your thumbs to dig into the knots and slowly release the pressure. Finish with a gentle head massage.

Frequently asked questions
The best type of exercise to build muscle is strength training. This includes resistance training, which causes muscles to grow by dealing with higher levels of resistance or weight. This process is known as muscle hypertrophy. However, cardiovascular activity is also important, as it burns calories to get rid of the fat between muscles and the skin, making the muscles appear more defined.
Diet is an important factor in muscle growth. Eating certain foods can increase muscle mass and reduce unhealthy dietary choices. For example, a diet with an increased vitamin intake can help build muscle. Additionally, consuming enough calories is crucial for muscle growth, as a calorie deficit can hinder muscle development.
Rest is essential for muscle growth and recovery. It allows the body to repair and rebuild muscle fibers, leading to increased muscle mass and strength. Aim to get enough sleep each night and incorporate rest days into your workout routine.
Here are some simple ways to nudge yourself towards building muscle:
- Lead by example — be physically active and motivate others to do the same.
- Share your story — use social media or other platforms to talk about your journey and the benefits you've experienced.
- Put footprints on the floor leading to stairwells to encourage stair use instead of taking the elevator.
- Use a motivational quote as a screensaver on your electronic devices.
- Make exercising your "go-to" choice by keeping your workout equipment easily accessible.
