If you are in the market for a weight gainer, there are a couple of things to consider.  A product that tastes well, is easy to mix, easy to digest and one that has the right formulation to work for you.  These are things that we looked at when we reviewed some of the best options on the market. There is no set rule on the exact amount of protein that you need to make those gains happen.  Everyone is different and everyone’s body reacts differently to different nutritional protocols. If you are going to be a hardcore trainer with a persistent resistance program that is geared towards helping you increase your muscle growth about.7 to .9 grams of protein per pound of your body weight is a good measurement to go by.  Teenagers are a bit different. For the younger groups, you’d want to add about 10% of your final number.

There are a number of factors you can look at and adjust to help you make the gains in mass that you are looking for.  You should have a solid training plan and nutritional regime. Train smartly and check out your reps you are pumping out.  Incorporating advanced strategies that can increase the intensity of your workouts can also help you succeed. Then when you need that extra boost, going towards supplementation is a great way to keep a well-rounded program going that will support all your hard work.  These products are all really great and they will provide you with the tools and backup to help you make your fitness goals a reality. It is definitely a specific type of training and nutrition that you need to engage in to get to massive gains.

Criteria Used in Choosing the Best Weight Gainers

The Right Formulation

When you are training for intense mass, you need an intense caloric intake.  In order to meet those requirements, these products are going to be a huge help for most people that cannot humanly eat as much as necessary to get the calories needed.  The other thing that is important is not necessarily calorie loading with any type of food, it is making sure that the calories you are consuming are not empty and won’t weigh you down.  These products are designed to be high calorie but also nutrient dense in a way that is going to support your body and your performance in the gym.

Believe it or not good, healthy fats can actually help you gain lean muscle mass and stay lean. The dietary fat that is used in these formulations will help to keep you sculpted and svelte.  Those products that have medium chain triglycerides and very little saturated fats are what to look for in this category.

Getting the right balance of creatine is another key feature of these products.  You are most likely taking creatine by itself, so it makes sense to make your supplementation routine easier by being able to take get your creatine with your protein mix.  It is great for your budget because you don’t have to buy as many products and it is effective with your time because you are getting a lot of what you need in one shake. The cool thing about the formulation of adding creatine is how creatine works the best.  It works the best with high amounts of quick acting carbs, which is what weight gainers utilize.

Easy to mix

There is no denying that ease of use is important.  It is really nice to have a well-rounded shake that you can add a bunch of fun extras to adjust to your palate like berries, nut butter, dissolvable fiber, and/or powders like matcha.  The reality is that you don’t always have a blender nearby when you need to get that quick shake in. Many times you are just leaving the gym and need to hit that sweet spot of time where your body is in optimal condition to take in and absorb nutrition.  So it is extremely important that the powder you use is easily mixed, that it can be dissolved in whatever liquid you decide to mix it with. If you can use a standard shaker to get your protein shake on hand, then you are in good shape. The last thing you are going to want to be chugging is lumpy, thick protein globs.

Tastes Well

To ensure that you actually take your supplements you should not be grossed out by them. The taste is important.  Remember these shakes are not milkshakes, they are performance shakes so don’t expect to have some luscious, rich and indulgent shake you have to be realistic.  However, there are many that taste pretty good overall. The cool thing is that many of the brands have multiple flavor options for you to choose from. So there is a good likelihood that you will be able to find one that is pleasing to your palate.

Easy to Digest

As you get to the higher calorie product lines be aware that if you are someone who is sensitive and struggle with indigestion these are the ones that can be the most irritating to your system. The best options are the ones that are the easiest on the stomach and don’t interfere with the rest of the “real food” you eat.  The best options can be broken down with ease by your body and all the great nutrition absorbed fully. You don’t want anything that is going to be heavy and keep you dragging. You want it in, absorbed and working fast.

Whenever you are using a new supplement give it some time before making a judgment call on its effectiveness or how our body is responding.  Many times you need to allow your body to have an adjustment time to get used to the new product. That being said, it should not be an overly long period of time that you are not feeling well or having issues with your digestion such as gas or diarrhea for example.  If you are not feeling great upwards towards a month plus, it is time to make a change.

Other Important Factors to Consider

Sometimes you might find that you have a weight that is gained but it is not sustainable weight from musculature.  Many times it is because of water retention that occurs with these products. Water retention can happen initially because of the creatine many are formulated with as well as the high amount of carbohydrates that you are taking in, with such high quantity.  Carbohydrates have extra water molecules in them. Don’t freak out or get discouraged, within a week or two you should see that excess water will be eliminated.

All of these products are high calorie but they aren’t the same across the board in how high.  There is much variability in the amounts of calories each brand has. Therefore make sure you know what your specific needs are so that you can use the right product.  There is a distinct difference between a shake that is 300 to 400 calories versus a 1200 calorie product. If you overdo on your calorie intake you will get big, that is for sure but probably not in the way you’d want.  It is going to be more fat than lean muscle, and that goes directly against what most people who are looking to bulk are working towards. So unless you are working with a trained professional, err on the lower side to start and see how your body responds.  If you need to increase, do so slowly so that you can better pinpoint exactly what the range is that works the best for your body.


Frequently Asked Questions

Q: Can you spot-reduce fat?

A: We all wish we could do this, but the reality is that you really can’t target just one or two areas.  What you can do is increase muscle gains in specific locations by using specific isolation exercises. So if your triceps are bothering you, you can definitely put a focus during your training on that area with as many specific strength training exercises targeted at pumping up that muscle.

Q: How many reps for muscle gains?

A: Really all the rep ranges will work for you.  Generally, if you are building muscle 8-12 reps is a good range to work with.  But don’t stay in this rigid range forever. If you have been doing this for a long amount of time you are not going to continue to get the returns that you are looking for.  Try increasing the weight and decreasing the reps. Then you can slowly get back to the 8-12 rep range with the higher weight and then keep it fresh and keep it cycled for continued improvements.

Q: What is German Volume Training?

A: It is a program of training and exercise that helps to increase muscle size.  It makes you work in a simple way by doing specific movement patterns and working on specific muscle groups.  It overloads your muscles and works them to exhaustion which helps with bulk and mass.
