This article will help you select the right P90x dumbbells and tell you why using dumbbells is better than resistance bands when performing the P90X workout.

In a hurry? Here are my top picks of the best adjustable dumbbells for P90x and P90x3:

See the overview, pros & cons below.

Why Are Using Dumbbells Better Than Resistance Bands When Performing the P90X Workout?

Dumbbells are the most common choice for performing the P90X workouts, and many gyms claim so.

Although dumbbells or resistance bands with the same weight/resistance are equally powerful and similar in helping you build and tone your muscles, accuracy is the major advantage of using dumbbells for P90X or P90X3 programs.

With dumbbells, you know how much exactly you are lifting, enabling you to track your progress much more easily and accurately compared with resistance bands. Moreover, if your goal is to build muscle mass, using free weights instead of resistance bands is a wiser and smarter choice.

If you compare them in terms of movement, they both offer a free range of movements without any restriction. The primary difference between dumbbells and resistance bands is that when you lift dumbbells, you against gravity. In the case of resistance bands, you lift them against tension.

You might feel a resistance band be better suited for travel purposes as they fit easily and are lightweight comparatively. In contrast, dumbbells are multi-fold times better in terms of durability and robustness.

If you ponder upon the long-lastingness of resistance bands, in logical terms too, you would understand that being made of materials such as latex and rubber, the bands are prone to easy wear and tear over time.

Hence, it is recommended that you choose what’s long-lasting and durable when you will invest in a piece of equipment that will stay with you for years.

How Heavy Your Dumbbells Should Be?

Rather than purchasing a pair of dumbbells with a fixed weight, it is better to procure a pair of adjustable dumbbells that do the trick in improving your fitness levels.

As per the P90X Fitness Guide suggestion, you are recommended to use dumbbells starting from as low as 5 pounds and going as high as 70 pounds.

This is mainly because you would not be restricting yourself to one or two exercises but push yourself harder doing numerous workouts that benefit your body—it is ideal to use lightweight resistance for exercises such as triceps kickbacks. In contrast, many others, such as heavy pants, require heavy resistance to bring about pronounced benefits.

Fixed vs. Adjustable Dumbbells—Which Are Better?

Your choice of fixed or adjustable dumbbells mainly depends on your availability of space, budget, and requirements. Still, most people prefer to use adjustable dumbbells as they offer more value for money.

If you have optimal space in your home to set up a full-fledged home gym for use, you might choose the fixed dumbbells. But if your choice is for fixed dumbbells, you need an entire rack dedicated to stocking dumbbells of different weights (from 5-60 lbs.).

Fixed dumbbells also prevent the need to pause your video during the P90X session and adjust the weights as you can quickly grab what’s required from your rack.

If your choice is for the adjustable variety, you will save ample space and a good amount of money. Also, many adjustable dumbbells are technical-rich. For instance, the SelectTech 560 model by Bowflex includes Bluetooth connectivity using which you can sync and record sets, reps, and the weights used.
