Some people are interested in increasing muscle mass to enhance their look, strength and power.  The Australian Institute of Sport helps grow our countries best muscles and here, they help the rest of us. There is a lot of confusion as to how to go about increasing muscle size and function but here is a step by step guide to 'grow your own'.

Step 1: Start with a good training program
Muscles need stimulation to grow.  Seek expert advice from a reputable strength coach. Adjust your program as your strength develops.

 

Step 2: Set realistic goals
Everyone is after quick results when it comes to muscle development but the reality is that muscles take time to grow.  Everyone has a different genetic potential to develop muscle mass so your goals must be realistic for you.  Gains usually occur relatively quickly at the start of a training program then slow down as the body adjusts.  Most people want to increase muscle mass while simultaneously decreasing skinfolds.  This is difficult to do, as one goal is a product of a negative energy balance (intake that is less than requirements), while the other is best achieved in the face of a positive energy balance.  It is important to prioritise body composition goals.

 

Step 3: Support your training with a high-energy diet that provides adequate protein
To gain muscle mass effectively, a positive energy balance of at least 2000-4000 kilojoules per day is required.  This calls for a general increase in dietary intake.  However, carbohydrate is the first nutrient to focus on, since muscle must be fuelled to do the training to stimulate muscles to grow.  It is also important for people trying to gain muscle mass to meet their increased protein needs, but huge protein intakes are not required.  In most cases, a high-energy diet that provides 1.2-2g of protein per kilogram of body mass will ensure that protein needs are met.  These protein intakes are easily met by consuming a varied diet that meets your energy needs.  Consuming protein above this level does not have an anabolic effect.  Excess protein will be oxidised as an energy source and may contribute to gains in body fat.  Very high protein diets displace other important nutrients from the diet and can be a source of saturated fat.  Although it is important to achieve energy needs, a high-energy diet should not be seen as an excuse for gluttony.  Excess consumption of high-fat foods can lead to excessive energy intake, and a greater risk of gaining fat mass rather than muscle.

Step 4: Get organised
Increasing your energy intake is not always easy.  Many people with high-energy needs are surprised to find they consume less than they think.  It requires considerable organisation and commitment to consistently consume a high-energy intake.  This includes having a planned approach to shopping and cooking to ensure appropriate foods are available, and carrying snacks around during the day to avoid missing snacks or having to rely on less suitable options.

Step 5: Eat and drink frequently
Eating more frequently, rather than increasing the amount of food you consume at each meal, is a more effective way to ensure an increase in food and energy intake.  People who try to cram their nutritional needs into three meals will often suffer stomach discomfort from the sheer size of meals and end up abandoning the plan.  Compact snacks and high-energy drinks offer an efficient way to top up between meals without filling up.  Good choices include milk shakes and fruit smoothies, liquid meal supplements, cereal and sports bars, and flavoured dairy foods such as yoghurt.

Step 6: Time meals and snacks appropriately
Including a small serve of protein with all meals and snacks will optimise amino acid levels in the blood and may facilitate muscle development. Remember that protein comes from a wide range of sources including bread, breakfast cereal, rice and dairy products - it is not just found in meat. Eating a carbohydrate-rich, moderate-protein snack or meal immediately after training may help to optimise gains in muscle mass by increasing production of anabolic hormones, reducing protein breakdown and supplying amino acids for protein synthesis. This snack may be even more effective when consumed before the session, in the case of weight training workouts. At the AIS, they encourage athletes to consume a snack providing 1g of carbohydrate per kilogram of body weight plus 10-20 g of protein within 30 minutes of finishing training.

Step 7: Be patient and consistent
Increases in body mass of 2-4 kg per month are generally considered achievable but individuals can respond differently to strength training.  It is important to be consistent with your training and your diet.  Some athletes fall into the trap of training and eating well for a couple of days then slacking off for a couple of days.  A spasmodic approach to training and nutrition will slow your progress down.

Step 8: Seek qualified advice before taking supplements
There are numerous supplements available on the market which promise to increase muscle mass and strength.  The majority of these products and their claims are not based on scientific evidence and are, therefore, a waste of money. Although protein powders are all the rage in muscle building circles, these products are generally too low in carbohydrate, excessive in protein - and too expensive.   However, there are a small number of supplements that may be useful for some athletes under specific circumstances.  For most people wanting to increase muscle mass, the most useful supplement is one that provides carbohydrate plus moderate levels of protein and other nutrients. 

Step 9: Monitor your progress and adjust when necessary
Individuals can respond very differently to training and nutrition programs. Some degree of trial and error is always required. Keep track of your start point, progress and improvements. Record good ideas, questions for your trainer and techniques you find that work well.

Step 10: Rest and recover
Muscle growth, repair and maintenance occurs during muscle rest. Avoid overtraining as insufficient rest can cause muscle catabolism and wastage. Always stretch after your workout to maintain your flexibility, range of motion and avoid injury.
