What Equipment Do You Need to Build Muscle?

One of the most common questions we get is, “What equipment do I need to build muscle?” You can use a few different setups, but some setups are particularly good for gaining muscle size and strength.

In this article, we’ll go over the pros and cons of:

  • Training at a commercial gym.
  • Building a barbell home gym.
  • Building a dumbbell home gym.
  • Using resistance bands.
  • Doing bodyweight training.

All of these options are viable. You can build muscle with anything. Even your own bodyweight. But some of these setups make it easier than others, and they each have their pros and cons.

Training at a Commercial Gym

No surprise that if you go to a commercial gym, they’ll have everything you need to build muscle. They’ve got dumbbells, barbells, exercise machines, and cable machines. All of those are great for building muscle. They’re stable exercises that allow us to load a little bit more weight every workout.

The downside is that it can be inconvenient. In addition to the time it takes to do your workout, you need to budget for the time it takes to travel there and back. That can add up, especially if you’re trying to squeeze in your workouts before work or after the kids go to bed.

The main downside we hear about, though, is that it can be a bit intimidating to go to the gym as a skinny beginner all by yourself. And I totally get that. I used to feel that way, too. I gained a full twenty pounds before building up the courage to go to a commercial gym. I shouldn’t have felt that way. Skinny beginners are welcome at every gym I’ve ever been to. Everyone there was a beginner once, too. But I understand the hesitation.

Building a Barbell Home Gym

A barbell home gym is an efficient way to train at home. Barbells make building muscle very easy. They’re very stable, they’re easy to load up gradually heavier, and barbell exercises tend to engage the most muscle mass, making your workouts extremely efficient.

The downside is that a barbell home gym will run you $1,000–4,000 if you buy it from a high-quality brand like Rogue Fitness, and they take up a lot of space. For people with some disposable income and a spare room, garage, or basement, it’s perfect. For people living in smaller houses or apartments, it’s a no-go.

I’ve gone to commercial gyms, used a dumbbell home gym, and used a barbell home gym. The barbell home gym is by far my favourite, and it’s how Cassandra and I train now. It’s great.

Building a Dumbbell Home Gym

A dumbbell home gym is the most versatile way to train at home. You can load your adjustable dumbbells gradually heavier, you can do a staggering number of different exercises, and you won’t have any problems stimulating muscle growth. Then, when you’re done, you can store them in a closet. Back when I lived in a small apartment, I kept a pair of adjustable dumbbells and an adjustable bench in my closet. I’d bring them into my living room and then put them away again.

The downside to buying dumbbells is that they can be expensive. There are plenty of cheap options, but it can be a hassle to adjust the weight, they’re hard to balance on their sides, and they can sometimes feel unwieldy. None of these are dealbreakers. You’ll still do fine. But they’re downsides.

The premium adjustable dumbbell brands completely solve all of these problems. But buying a nice pair of PowerBlock, IronMaster, or BowFlex dumbbells can run you nearly a thousand dollars, especially if you’re getting a workout bench and a chin-up bar along with them. They’re worth it, but they aren’t that much cheaper than a barbell home gym.

Dumbbells and barbells have a couple of key differences:

  • Barbell lifts are heavier, engaging more muscle mass and putting more load on your spine, making them efficient but fatiguing. Dumbbell lifts are lighter, demanding more stabilizer strength, making them less efficient but also less fatiguing.
  • Barbell lifts lock your hands in place, forcing specific movement patterns, and making the lifts feel a bit easier. Dumbbells allow you to move more freely, making them easier on your joints, but also making them feel a bit harder.
  • There are only so many lifts you can do with a barbell. Dumbbells offer quite a bit more flexbility.

As for gaining muscle and strength, though, both barbells and dumbbells are pretty much perfect. Whichever approach you take, you can gain muscle and strength at full speed. These are the two best tools for building muscle in the world.

Using Resistance Bands

Resistance bands are popular because they’re cheap and portable. The problem is, they’re hard to load gradually heavier, and the movements you can do with them are somewhat limited. Perhaps most importantly, they make it difficult to challenge our muscles through a deep range of motion. That’s why serious lifters rarely use them. But even for casual lifters, they can make it harder to build muscle.

The main downside to resistance bands is that they get progressively more challenging as you stretch them further. As a result, the deep part of the range of motion tends to be much easier than the top part. This isn’t a resistance curve that occurs in nature, and it doesn’t seem to line up very well with our natural strength curves. Plus, it’s the deepest part of the range of motion where our muscles are strongest, where muscle tension is the highest, and where we stimulate the most muscle growth. If we minimize the challenge at the bottom of our lifts, we make it harder to build muscle.

With that said, you can build muscle with almost anything. Resistance bands do put resistance on your muscles. You may not build muscle as fast, but you can still build muscle. That’s where the second problem comes in: resistance-band workouts hurt! When you shift so much emphasis to the lockout portion of the lift, you get a crazy burn and tons of pain. It feels like you’re working damn hard. But the training is less effective, so you need to push through more pain, doing even more reps, even more sets. It makes building muscle hard.

Resistance bands can be handy to have around, though. Combining them with barbell lifts (accommodating resistance) may even improve the resistance curve. Plus, there are some good resistance-band drills and exercises. But we don’t usually recommend using only resistance bands to build muscle.

Doing Bodyweight Workouts

Bodyweight workouts are popular because they’re even cheaper and more portable than resistance bands. They’re also even harder to progressively load heavier, making the workouts a bit more complicated. But on the bright side, they are ideal for building muscle.

Just like with barbells and dumbbells, lifting your own body weight is a very natural thing to do. The resistance curves align well with our strength curves. The lifts are most challenging near the bottom, where your muscles are stretched—where your muscles are strongest. This makes bodyweight exercises perfect for stimulating muscle growth.

The downside is that, similar to resistance bands, bodyweight workouts can be super painful, especially as you start to get stronger. Building your way up to 20 push-ups isn’t so bad. But doing bodyweight squats can be pretty rough. You’ll need to delve into higher rep ranges. And the more reps you do, the more your muscles will burn, the more your body will beg you to give up, and the harder it will be to get into the habit of consistently working out.

As a result, we usually recommend getting some adjustable dumbbells, even if they’re super cheap. If you hold a dumbbell in your hands, all of a sudden, your squats are heavier, you won’t need to do as many reps, and they won’t feel so hard. But if you want to start with bodyweight training, rest assured that you can build a tremendous amount of muscle. You’ll just need to grit your teeth.

You can build muscle with anything, including your own bodyweight. If you challenge your strength and fight to grow stronger over time, you can stimulate muscle growth. If you combine those workouts with a good muscle-building diet, you’ll grow bigger and stronger. With that said, some equipment makes it much easier to build muscle. If you can manage it, the three best setups for building muscle are:

  • Commercial gym—10/10: ideal for exercise variety.
  • Barbell home gym—10/10:, ideal for large homes.
  • Adjustable dumbbells—10/10: ideal for apartments.

All three of those options are perfect. I mean, technically, you might be able to argue that a commercial gym is best. And you’d kind of be right. Commercial gyms have the widest variety of exercises, and it’s definitely nice to have access to a leg press machine, cables, barbells, and dumbbells. But you can gain just as much muscle and strength with a barbell or dumbbell home gym, and your workouts will be similarly efficient.

If you can’t train at a commercial gym or build a home gym, we recommend starting with bodyweight training. It’s great for building muscle. The main downside is that it hurts. And it can also be a bit more complicated. But if you can tough it out, you’ll do great.
