The Bigness Project Review – Insider Look Into This Hypertrophy Plan

The Bigness Project is a hypertrophy training plan for men and women designed to increase muscle size with a workout method based on lower loads, higher repetitions, minimal rest between sets, an emphasis on the eccentric part of reps, and mind-muscle connection.

It is not a powerlifting plan for strength, but it can be used as a periodization alternative in order to spur muscle gains, on which to build more strength later on when switching back to lower reps and heavier weights.

The plan comes in two different packages, with or without a cardio plan, plus an optional nutritional plan, if desired. Stay here to find out what this plan by Jen Sinkler and Kourtney Thomas has to offer and whether it is for you.

Who Is The Bigness Project For?

This is a program for everyone, men and women, beginners to advanced, young and old. It can be used either as a stand-alone protocol for hypertrophy or as a welcome periodization plan to break through strength training plateaus.

It is not a functional strength, skill performance plan, but a training method useful to achieve the greatest possible muscle gains or to set the foundations for extra strength gains, so this plan may be suitable to regular gym warriors or powerlifters who need a rest from heavy lifting in order to break through stagnation.

The Bigness Project Review

What Is The Bigness Project?

The Bigness Project is purely a hypertrophy program for getting as muscular and big as possible. It is not a strength program, but it can also increase strength as a secondary side effect.

This is because strength is not only the result of an efficient central nervous system and fast-twitch fiber activation but also the net result of your muscle cross-section area.

The bigger the muscle, the greater its strength, anything else being equal, like specific strength conditioning and nutrition. This is because this program can also prepare the foundations for bigger strength gains later on when you switch to a pure strength regimen.

Beginners may increase both muscle mass and strength with this program, while advanced lifters or powerlifters stuck in a strength plateau may find the Bigness Project hypertrophy training the ideal method to stimulate progression once more, before switching back to strength training again.

The Bigness Project Workouts

The program works on a 14/week schedule, four to five times a week. The workout sessions are designed in a split fashion, with one or two body parts each session, each muscle group did once a week.

This means you must keep a schedule throughout the week, or else your total body workout for the week will be compromised. The first seven weeks are scheduled with four workouts per week, each taking 45 minutes to one hour to complete, while the remaining seven weeks require five workout sessions per week lasting one hour to one hour and a half each.

The techniques involved are primarily for hypertrophy, with strength gains possible as a side effect of size increase, depending on your current fitness levels and training history.

This means performing repetitions in the range of  8 to 15 with one-minute rest between sets. But this is not the only factor. Time Under Tension and correct form come into play as well.

The Mind-Muscle Connection

The program stresses the importance of proper execution, making each repetition count, focusing on your muscle working rather than simply lifting the weight up and down as a task.

In other words, it is about using the weights to feel the muscle and get it working, rather than using the muscles to simply lift the weight. In order to do so, the Bigness Project method recommends developing a sensitivity for mind and muscle connection by deliberately slowing down the pace.

This may require reducing the weight on the barbell even further, an important aspect of hypertrophy training that may be a hard pill to swallow for gym warriors used to pure strength training.

However, this simple “regression” to lighter weights is only temporary and can greatly contribute to further strength gains down the line.

Bigness Project Eccentrics

The Importance Of  Slow Eccentrics

The single most important technique recommended in the program to achieve a better execution and a greater awareness of your muscle working through the set is the slowing down of the eccentric part of a repetition.

There are actually 3 different kinds of eccentrics:  sub-maximal eccentrics, maximal eccentrics, and supra-maximal eccentrics, but the eccentrics employed in the Bigness Project are only the sub-maximal ones, as the other two types are way too taxing for your tendons and joints and always require a spotter’s assistance.

Consider that since your muscle strength is greater in the eccentric portion, in supra-maximal eccentrics you can lower a weight that is up to 30% heavier than your 1 repetition max concentric, but this is a really advanced technique for professional lifters, very stressful on your joints and ligaments.

Instead, the sub-maximal eccentrics recommended in the program are a tried and tested method that has been around for ages and is easy to implement. It works very well with moderate weights, but less so with heavier weights because the high motor unit threshold used in heavier weights allows for less slow-speed control.

Instead, with lower resistance it is possible to slow down the eccentric part by a long margin, making the muscle work harder for longer, but it may require stripping down the weight even further than a straight-set performed without slow eccentrics.

This is no problem in this program. It is not about ego-boosting weight lifting records, but about working your muscles as hard as possible, with the right combination of total work volume, intensity, rest, frequency, and nutrition.

Slow, sub-maximal eccentrics in particular create more micro-tears than the concentric part of a set, setting the ground for extra muscle tissue repair and extra gains afterward.

Sub-maximal eccentrics work great for building mass but also strength in beginner, intermediate and advanced trainees, and its beneficial effects have been well documented and studied. See here and here.

The program advocates a tempo of 3 to 5 seconds eccentric and a load in the range of 60 to 85 percent of your max for effectiveness and safety. As an added bonus, slow, hypertrophy training is beneficial for your joints and tendons, an important consideration especially for older athletes and gym-goers who want to get fit without getting injured.

All in all, the Bigness Project offers a sound and tested method for getting big muscles in a safe and sustainable way, preventing injury, and building the foundation for further strength gains.

What About Cardio?

The cardio part of the plan is included only in the GOLD version. According to the author, cardio training in addition to resistance training can help increase muscle gains, rather than being an obstacle, improving cardiovascular performance in the process.

This is because by default hypertrophy decreases blood capillaries relative to the size of the muscles, lowering the amount of blood flow as a result.

Cardio training offsets this situation by helping build new blood capillaries, which in turn lead to better oxygen and nutrients transportation. The Cardio Calendars of the plan layout a strategy to maximize your muscle size along with a healthy heart.

This is all good and well, but if you have your own cardio regimen in place and you know it works, you may want to skip on this information and stick to the workouts or consider the nutritional part instead.

The RP Bigness Project Nutritional Guide

This part of the program is optional, both for the SILVER and GOLD versions, meaning that you can get it with or without the cardio part if you wish. The logic for it is that, according to Jen, the training regimen for hypertrophy is so effective that it works very well for beginners and intermediates even without any particular nutritional plan.

However, if you have already a training history and want to give your muscles the best chance to achieve their full hypertrophy potential, the Bigness Program comes with this optional nutritional plan called RP Bigness Plan.

RP stands for Renaissance Periodization, which is a diet program for athletes by world-famous coach Ph.D. Mike IsraetelThis nutrition guide recommends about a gram per pound of bodyweight of proteins per day, which is about standard practice for hypertrophy, with correct guidance on macro-nutrients ratios and calorie input.

Dr. Mike Israetel needs no introduction, he is a leader in nutrition and training with outstanding results both for his clients and himself, as he is also a professional bodybuilder and power-lifter holding many records.

The RP Bigness Plan diet was written more with fitness enthusiasts in mind, those who want to get as big as possible with the program, but it needs to be paid extra for.

This diet plan is structured in a simple way despite its scientific background and is easy to follow. Basically, it offers two options, one with a balanced macro-nutrient content and one that is low-carb, plus a list of recommended foods and meal planning.

Depending on your lifestyle and job commitment, you can split your daily intake into three or four meals. By default, the plan is written for maintenance mode, which means you can expect to keep the same body weight while changing your body composition, that is more muscle and less fat.

But you can also tweak the nutrition up or down in calories and proteins to suit a more specific goal, like more muscle building or more fat burning. In addition to this, the RP Bigness Project diet plan also offers private coaching.

Closing Thoughts

The Bigness Project is a well-laid out and feasible hypertrophy training plan that teaches you how to increase your muscle size in the shortest possible time. It is not a pure strength plan, though strength gains are also included as a bypass product of the increase in muscle mass.

This hypertrophy protocol can be used by anyone for muscle gains or even by powerlifters who need to switch to lighter weights and hypertrophy mode for a while in order to break through adaptation and get even stronger later.

The Bigness Project is also very safe and kind on joints and tendons, as it implies the use of moderate loads, emphasizing proper form and a slow tempo, making it suitable for older people too.

To sum up, if you are looking for a safe and practical approach primarily to sustainable muscle gains with strength increases as a secondary bonus, this program is very well worth considering.
