Best Exercises for Building Muscle Mass

The Only 6 Exercises You Actually Need

The best exercises for building muscle mass aren't the 20 different machines you see online; they are the 6 foundational compound lifts that build over 80% of your physique. If you're frustrated because you've been spending hours in the gym doing endless bicep curls and leg extensions with little to show for it, you're not alone. The fitness industry sells complexity because it's confusing, and confusion keeps you buying new programs. The truth is much simpler. Building a strong, muscular frame comes down to mastering a handful of movements that force your entire body to work and grow. These aren't fancy, but they are brutally effective. They've worked for 100 years and will work for 100 more. Everything else is secondary. The foundation of your entire training program should be built on these six pillars:

1. The Squat: The undisputed king for lower body development. It hits your quads, hamstrings, glutes, and core in one single movement.
2. The Deadlift: The ultimate full-body strength builder. It works everything from your traps down to your calves.
3. The Bench Press: The primary movement for building a powerful chest, shoulders, and triceps.
4. The Overhead Press (OHP): The best exercise for building strong, broad shoulders. It also heavily involves the triceps and upper chest.
5. The Barbell Row: The cornerstone of a thick, muscular back. It develops your lats, rhomboids, traps, and biceps.
6. The Pull-Up / Chin-Up: The best bodyweight movement for building a wide back and big biceps. Nothing builds that V-taper shape better.

That's it. Every single successful muscle-building program in history has been built around variations of these six movements. If you dedicate the next 6 months to getting brutally strong at these lifts, you will build more muscle than you would in 2 years of messing around with machines and isolation exercises.

Why Your Current Workout Fails (It's Not Your Effort)

You're working hard, but you're not growing. The reason isn't your work ethic; it's your exercise selection. You're likely spending 90% of your energy on exercises that only produce 10% of the results. This is the critical difference between compound and isolation exercises.

A compound exercise is a multi-joint movement that recruits large amounts of muscle mass. A squat, for example, involves movement at the hip, knee, and ankle joints, engaging dozens of muscles simultaneously. An isolation exercise is a single-joint movement that targets one small muscle group. A leg extension only involves movement at the knee joint to work the quadriceps.

Think of it like this: Building your body is like building a house.

• Compound Lifts (Squats, Deadlifts, etc.) are pouring the concrete foundation, erecting the frame, and putting on the roof. This is the heavy work that creates the structure.
• Isolation Lifts (Curls, Leg Extensions, etc.) are painting the trim and picking out doorknobs. They are finishing touches.

Too many people spend all their time picking out doorknobs while their house has no foundation. Your body grows in response to a signal. The strongest signal you can send for muscle growth is lifting heavy loads through a large range of motion. A 225-pound squat places hundreds of pounds of stress on your entire system, forcing your body to release growth hormones and adapt by building muscle everywhere. A 70-pound leg extension places a small amount of stress on one muscle. The signal is a whisper, not a shout. Your body has no compelling reason to grow. Stop majoring in the minors. Focus your energy on the big 6 lifts that provide the powerful growth signal your body needs.

The 3-Day Plan That Puts These Lifts to Work

This isn't a complicated plan. It's a simple, proven, full-body routine designed for one thing: building muscle mass. You will train 3 non-consecutive days per week, for example: Monday, Wednesday, and Friday. This allows for 48 hours of recovery between sessions, which is when your muscles actually grow. You will alternate between two workouts, Workout A and Workout B.

Step 1: The Workout A / Workout B Structure

Your weekly schedule will look like this:

• Week 1: Monday (A), Wednesday (B), Friday (A)
• Week 2: Monday (B), Wednesday (A), Friday (B)

This rotation ensures you are hitting every major muscle group with enough frequency to stimulate growth but also with enough rest to recover and get stronger. Each workout should take you about 45-60 minutes. Your goal is not to live in the gym; it's to get in, stimulate the muscle, and get out so you can recover.

Step 2: Workout A Details

This workout is your foundation for pushing strength and lower body development.

• Barbell Squat: 3 sets of 5-8 reps
• Bench Press: 3 sets of 5-8 reps
• Barbell Row: 3 sets of 5-8 reps
• Accessory Lifts (Optional): Choose two from the list below for 2-3 sets of 10-15 reps.
• Bicep Curls
• Tricep Pushdowns
• Lateral Raises

For the main 3 lifts, rest 2-3 minutes between sets. For accessory lifts, rest 60 seconds. Choose a weight where the last rep is a struggle, but your form is still perfect. If you can do 8 reps, add 5 pounds at the next workout.

Step 3: Workout B Details

This workout focuses on pulling strength and overall power.

• Deadlift: 1 set of 5 reps (Deadlifts are very taxing; one heavy set is enough for beginners)
• Overhead Press: 3 sets of 5-8 reps
• Pull-Ups (or Lat Pulldowns): 3 sets to failure (or 8-12 reps on pulldowns)
• Accessory Lifts (Optional): Choose two from the list below for 2-3 sets of 10-15 reps.
• Face Pulls
• Leg Press
• Ab Crunches

Again, rest 2-3 minutes for the main lifts and 60 seconds for accessories. For pull-ups, do as many as you can with good form. If you can't do any, use an assisted machine or substitute with Lat Pulldowns. Once you can do more than 8 pull-ups in a set, start adding weight with a dip belt.

Week 1 Will Feel Wrong. That's the Point.

Starting a proper strength program feels different from the random workouts you're used to. You need to know what to expect so you don't quit before the real results begin.

• Weeks 1-2: The Learning Phase. You will be sore. Very sore. This is your body adapting to new movements. Your main goal is not to lift heavy; it's to master the form of the 6 core lifts. Film yourself or work with someone experienced. You might even feel weaker as your nervous system learns to coordinate these complex movements. This is 100% normal. Stick with it.
• Month 1: The Neurological Gains. Your strength will shoot up quickly. You might add 20-30 pounds to your squat and bench press in the first month. This isn't all new muscle yet; it's your brain getting more efficient at firing the muscles you already have. You'll start to feel more solid and your clothes will fit a bit better, but visible muscle gain is just beginning.
• Months 2-3: The Visible Growth. This is where the magic happens. Your neurological gains will slow down, but your actual muscle growth (hypertrophy) will take over. If you are eating enough protein and calories, you can realistically expect to gain 1-2 pounds of lean muscle per month. This is significant. After 90 days, you will see a clear difference in the mirror, especially in your legs, back, and shoulders. You should be lifting 30-50 pounds more on your main lifts than when you started. This is what real progress looks like.

You read this far. You're serious.

Frequently Asked Questions

Choosing the Right Starting Weight

Start with just the empty 45-pound barbell for all lifts to practice the form. Once you're comfortable, find a weight you can lift for 8-10 reps with perfect form, but not 11. This is your starting weight for your 3 sets of 5-8 reps. It's better to start too light and progress than to start too heavy and get injured.

Progressive Overload Explained Simply

To build muscle, you must consistently challenge your body. This is progressive overload. Each week, your goal is to do slightly more than last week. This can be adding 5 pounds to the bar, doing one more rep with the same weight, or doing the same weight and reps with better form. Track every workout in a notebook.

The Role of Diet in Muscle Growth

You can't build a house without bricks. Your diet is the raw material for muscle. To maximize growth, aim for two things: 1) Eat 0.8 to 1 gram of protein per pound of your body weight daily. For a 180-pound person, that's 144-180 grams. 2) Eat in a slight calorie surplus of 200-300 calories over your maintenance level.

What to Do If You Can't Perform an Exercise

Not everyone can do every exercise due to mobility or equipment limits. Use smart substitutions. If you can't barbell back squat, use goblet squats or the leg press. If a barbell bench press hurts your shoulders, use dumbbell bench presses. The movement pattern is more important than the specific tool.

How Much Rest Between Sets

For heavy compound lifts in the 5-8 rep range, you need to rest for 2-3 minutes between sets. This allows your nervous system and energy stores to recover so you can give maximum effort on the next set. For smaller accessory lifts in the 10-15 rep range, 60-90 seconds of rest is sufficient.
