Leg day can prove more demanding than any other day of the week because exercises like squats use larger muscle groups. The quads are some of the largest muscles in the body and can require more weight and volume to grow and strengthen. 

You might think of squats first when you think of training your quads, but they're not the only exercise that can target this muscle group. Using dumbbells instead of a barbell can also add unique benefits to your strength and performance. 

Importance of the Quads 

The quads aren't just there to help your legs look strong and sculpted. Their main responsibility is to flex the knee and extend the hip. These muscles help to stabilize the knee cap during anytime of movement. Whenever you run, walk, jump, or kick, you're using your quadriceps. Let's take a deeper look. 

Looking at The Quads 

Look down at the front of your thigh. The muscle that you can see is your quadriceps femoris.

This is a four-headed muscle that is in turn made up of four unique parts: 

• Vastus Lateralis 
• Rectus Femoris 
• Vastus Medialis 
• Vastus Intermedius 

Each of the four heads of the muscle starts at the femur and connects to your kneecap. The main function of the quads is to extend your leg from your knee. It also stabilizes the patella, which is the small bone in front of the knee.

Starting from the outside of the leg to the inside, here is a short description of each of the four muscles:

• Vastus Lateralis: This is the biggest part of the quads. You can find the vastus lateralis on the outer side of the upper thigh. Apart from supporting leg extension and patella stabilization, it also plays a part in helping you rise from the bottom of a squat. 
• Rectus Femoris: This muscle is found in the center of the front of the thigh. It is the only quad muscle that can flex the hip and thigh. You can see this for yourself if you extend your leg straight out and up and then contract the quad at the top and slowly lower your leg.
• Vastus Medialis: This part of the muscle can be found on the inside of your thigh, and it's popular in the world of bodybuilding because of its unique shape. Building this muscle can really thicken the appearance of your thighs.
• Vastus Intermedius: This muscle lies beneath the rectus femoris, so it can sometimes be hard to target. Squats are excellent exercises, but there's a lot more to training your quads than just that one foundational movement.

Best Dumbbell Quad Exercises

To train your quads, you can use dumbbells, kettlebells, or barbells. Dumbbells and kettlebells work in a more similar way than a barbell does as they can provide more unilateral work. They can also require more stability than a barbell because the weight isn't equally distributed.  

With dumbbells, each side pulls its own weight so you can improve your weaker side quickly. 

Below are some of the best dumbbell quad exercises for building strength. Many of these exercises are ideal for beginners as well as advanced bodybuilders. Integrating them into your routine can have you building bigger, stronger legs in no time.

Why Use Dumbbells?

Dumbbells can provide unilateral benefits that you just can't get from a barbell. With a barbell, if one side is weaker than the other, the stronger side can compensate for that weakness, creating more muscle imbalances.

If you don't correct these imbalances, they can turn into a bigger issue for performance and can put you at a higher risk for injury. 

Dumbbells can also help improve grip strength. The better your grip, the more weight you can hold, meaning you can lift heavier with stronger hands, wrists, and forearms. 

Getting the Results You Want

Although you might normally rush to the squat rack on leg day, it can be beneficial to change it up every now and then. Give the barbell a rest for the day and grab some dumbbells to help grow those quads.

Remember, quads are a big, strong muscle, they need their rest as well.
