Building Lean Muscle for a Lean, Fit, and Sculpted Physique With Resistance Training and Healthy Nutrition

Building Lean Muscle Workout

Building lean muscle is the foundation for creating an attractive, sharp, muscular build. Yes…it takes work, but it is not a complicated process. Anyone can do it with a little discipline and solid dose of motivation.

Building Lean MuscleAfter the first 6 to 8 weeks, your motivation will likely become self-perpetuating. There’s a lot to be said for the old saying…success breeds success. As you start to see improvements in your physique and your old clothes start to fit again, that will fuel your motivation.

And forget the myth that you are either losing fat or gaining muscle, but not both at the same time. You can build lean muscle, while at the same time losing that unwanted fat. And the simple way to transform your physique is through effective workouts, along with a clean diet.

The physique that most people admire and strive for is not the overbuilt, musclehead look. That is not the preferred look for the average person.  Why?

  1. You probably don’t have 2 hours a day to spend in the gym.
  2. More importantly, you recognize (like most people) that the most attractive build is lean and hard, not huge and overdone.

Start a journey, step by step, to a new you. All of the tools (and more) are here for you to help you build lean muscle and lose fat.

Main Takeaways

  • Building lean muscle takes work, but you can do it with proper discipline and motivation.

  • Resistance training is the key to building lean muscle, and you need to put your muscles under stress. "Going through the motions" will not do a lot.

  • Your diet goes hand-in-hand with your resistance training in order to build lean muscle, so lots of healthy proteins.

Lean Muscle Loss With Age

Muscle Loss With AgeYour efforts in building lean muscle become doubly important as you age. After the age of 30, the average person loses 3% to 5% of their lean muscle mass each decade. This is known as sarcopenia, and it can have a devastating effect on your physique unless you take some simple steps to prevent and mitigate this. (1)

You just need to take simple action to reverse the natural process, but it can be reversed.

Much of the science also says that even if you exercise and workout, you will still lose muscle mass each decade after 30 or 40. Not true. Many have proven that you can build lean muscle in your 30’s, 40’s, 50’s, 60’s, and beyond with solid workouts, and a muscle building diet. You have likely seen the guy in the gym who looks mid-50’s or mid-60’s and is hard as a rock. Just takes some focus and motivation, and you will feel vigor and renewal as you progress down this road.

Resistance Training to Build Lean Muscle

Resistance training is different for everyone…pick the flavor that works best for you – gym equipment, free weights, bodyweight exercise, dumbbells, barbells, body weight, or some combination of all. They are all effective, as long as the resistance part is there and you do them consistently. That is the key, to do the workouts on a weekly basis and your muscles will stay fit.

Any resistance training will be greatly beneficial, but if you want to dive a little deeper it’s helpful to know some of the micro. The key is to understand required intensity, rep ranges, and rest times between sets.

We have two phases for developing a lean and muscular physique in just a few months. You just have to commit to putting your health first for a few months – diet and exercise. After that, you’ll be a believer and lifestyle changes will become part of your life!

Here are the 2 Phases:

  1. Phase 1 – Muscle Building
  2. Phase 2 – Muscle Hardening
Building Lean Muscle Plan

Phase 1 | Muscle Building [2-4 months]

Phase 1 Workouts

During Phase 1, which should last 2 to 4 months, your goal is to add muscle mass while starting to lean out. The way to add lean muscle mass is to perform 6 to 12 reps in each set, generally to muscle failure, and only rest 30 seconds between sets. This will completely fatigue and break down your muscles, which will then rebuild and grow on your rest days.

You need to lift heavy, but not so heavy that your form suffers or that you risk injury.

This phase can last anywhere from 2 months to 4 months, depending on your experience, personal goals, and current muscle mass.

  • 6 to 12 reps per set
  • 3 to 4 sets per muscle group
  • 30 seconds rest between sets
  • Muscle failure (or close to it) each set

Phase 1 Diet & Calories (2 mild cheat days per week)

Your calories are built around your weekends, so we are assuming a normal Friday-Saturday-Sunday weekend.

Target your resistance training days to be Friday and Saturday, so that your resistance training days coincide with your higher calorie days to properly feed your muscles during the hard work:

Sunday to Thursday (lower calories – weekdays):
(Target Weight) x 10
If weight goal is 200 pounds, 200 x 10 = 2,000 cal/day

Friday and Saturday (higher calories – weekends/workouts):
(Target Weight) X 15
If weight goal is 200 pounds, 200 x 15 = 3,000 cal/day

Phase 2 | Muscle Hardening [1-2 months]

Phase 2 Workouts

During Phase 2, your goal is to increase muscle density and therefore hardness. This will give you the lean and cut look. Increase the weight slightly and only perform 4 to 6 reps in each set. This increases the density of the muscle fiber.

Depending on your body fat % and your personal goals, this phase should last 1 to 2 months. It’s how you lean out for summer. Remember, abs start to show at 10% body fat (click to check your body fat %):

  • 4 to 6 reps per set (lower reps – heavier weight)
  • 2-3 sets per muscle group
  • 90 seconds rest between sets
  • 1 rep short of failure for each set

Phase 2 Calories & Diet (1 mild cheat day per week)

Your calories are built around your weekends, so that your resistance training days coincide with your high calorie day, which is just 1 cheat day during Phase 2:

Saturday to Thursday (lower calories – weekdays):
(Target Weight) x 8
If your goal is 200 pounds, 200 x 8 = 1,600

Friday (higher calories – weekend):
(Target Weight) x 12
If your goal is 200 pounds, 200 x 12 = 2,400

This is really just scratching the surface…here is a lot more detail about your muscle building diet

It’s also a good idea to have a good general idea of your calorie intake, as well as your calories burned.

Learn more about that here:

Carb Cycling

A key part of the schedule shown above in Phase 1 and Phase 2 is “carb cycling.” This is mainly important if you are an endomorph, and put on and retain weight easily (and don’t feel bad, as this is most people). If you’re not sure, click to learn more about the three main body types.

Make sure to have your 2 or 3 workout days (resistance training) on Friday and Saturday, which are cheat days for most people. You want your muscles to be well-fed on your 2 or 3 workout days, and you do that by doing your resistance training on Friday and Saturday…very helpful in building lean muscle.

You might have your other workout day (resistance training day) on one of your lean calorie days, and that’s OK too!

When to Do Cardio

Low Intensity CardioIt’s best to do cardio every day! Yes, every day, and here’s why.

In years of discussions about the best days to do cardio, so many people say “I do cardio Monday, Wednesday, and Friday.” The problem is that it’s then too easy to say, “well this week I’ll change it to only Wednesday and Friday.” This happens all the time!

So the best thing is to just build it into your routine. Cement into your routine, and commit to do cardio every day. It sounds like a lot and maybe even overwhelming, but when it becomes part of your daily routine it becomes very easy. And you’ll be grateful you did!

And as for the question of doing cardio before or after weights, learn more about that here.

If You’re Stuck…Focus on the Basics

Creating muscle growth through your workout regimen is simple, but it’s not easy! The advice above, and throughout this site, is to build a lean and muscular physique. It is not to achieve bodybuilder status. That is not who we are at A Lean Life.

But the basics to build a lean and muscular physique and achieve effective muscle growth, is to eat a balanced and nutritious diet, and do resistance training 2 to 4 times a week. If you do this, you can achieve solid muscle growth and build muscle over time.

And unless you’re taking steroids, it does not happen quickly, and nor should it! You want to achieve your desired physique over several months, and not a few weeks. It is very possible to lose fat and build muscle at the same time. I can speak from very personal experience in doing that.

Most Americans (70%+) are overweight or obese. So if you fall into that category like I used to, then you want your calorie intake to be 500 calories less than you consume on a consistent basis to lose fat and build muscle. If you are too focused on losing fat and you drop your calories to an unsustainable point (1000 calorie daily deficit), then it is hard to build muscle. The sweet spot is 500-750 calorie daily deficit on a consistent basis.

Power of Proper Nutrition

Proper nutrition is the cornerstone for muscle growth. And you want to have a good dose of protein as part of this nutrition plan. Protein contains key amino acids which are the building blocks for muscle growth. So eating a balanced and nutritious, diet packed with a good dose of protein, is a good blueprint for achieving this.

A Key Macronutrient

For solid and sustained muscle growth, proper nutrition and a good dose of protein is key. This will not only assist in muscle growth, but also improve your strength and overall health.

So when doing your daily exercise routine, make sure to consume ample protein in your diet.

How Much Protein Do You Need?

And if you’re wondering how much protein you need for muscle growth and building muscle, a good rule of thumb is .5 g of protein for each pound of body weight. So if you weigh 200 pounds, try to consume approximately 100 g of protein per day.

It is also recommended that you get a good dose of carbs and healthy fats also as part of healthy nutrition. Make sure you cover all of the macronutrients for not only your fitness regimen, but also your overall health.

  • Protein
  • Carbs
  • Fats

When to Take Protein

It’s a good practice to consume a healthy mix of protein, carbs, and healthy fats with every meal. And good variety is also a healthy power move, so mix it up.

And a great time to consume a heavy dose of protein is after your weightlifting session. I like to mix my favorite protein powder with skim milk within 30 minutes of my workouts. It’s a powerhouse move so that protein gets into your system pretty quickly. I like Tri-Protein for my protein powders, which was recently endorsed by Men’s Fitness, and you can check our complete review by clicking below.
