P90X3

by

Since P90X and P90X3 empowers its users to bypass gym membership fees, as well as eliminating the need for an extensive home gym, accessibility is a prime reason it has become astonishingly popular.

One of the best aspects of the P90X system is that it challenges you without the need for heavy, expensive equipment. Only a pull-up bar and either resistance bands or dumbbells are required.

Why Dumbbells Over Resistance Bands?

Gym rats claiming that dumbbells are objectively the best choice have it wrong. Studies have concluded that a dumbbell or resistance band with the same weight/resistance rating has the same ability to build and tone muscle.

Unlike workout machines, either offers a free range of motion as well. So your movements won’t be restricted in an unnatural manner.

The key difference here in terms of function is that with dumbbells you’re lifting against gravity while with resistance bands you’re lifting against tension.

Although resistance bands are great for travel, dumbbells are incredibly robust and a quality product can last a lifetime. Although manufacturers such as Bodylastics are beefing up their resistance bands so snapping is less likely, their offerings are made from materials that degrade over time (latex, rubber, etc.). If you’re working out at home why not choose what’s best in the long-term?

Range of Weights Recommended

For best results and to adapt to your current fitness capabilities, you’ll want a wide range of dumbbells at your disposal or adjustable dumbbells. Exercises such as triceps kickbacks require light weights, while others like heavy pants are intended to be executed with heavy resistance.

The P90X Fitness Guide suggests using a range of dumbbells starting at 5 pounds and going as high as 70 pounds.

Fixed vs. Adjustable Dumbbells

You’d need a rack filled with fixed dumbbells (ranging from 5 to 60 lbs.) to replace most adjustable dumbbells. So by going with an adjustable model, you’ll save space and if you need a comprehensive set, money too.

Adjustable dumbbell brands like Bowflex have gone high-tech. SelectTech 560 includes Bluetooth connectivity which syncs and records sets, reps and the weight used. Results are viewed via the Bowflex SelectTech App.

People with plenty of space looking to build a more professional gym at home may prefer the convenience of traditional dumbbells. Rather than pausing the P90X video to change the weight of your adjustable dumbbells, you’ve got the ability to quickly grab what is needed from a rack.

Most people however, will be better off going with adjustable dumbbells as they offer a greater value.

Which Adjustable Dumbbells to Choose?

Bowflex and PowerBlock are the most popular makers of adjustable dumbbells, and within these two camps the choices are simple.

There is essentially an option for average fitness needs and an amped up version for fitness enthusiasts, power lifters and athletes. Specifically, the Bowflex SelectTech 552/560 or PowerBlock Personal Trainer Set is for most people, and the SelectTech 1090 or PowerBlock Elite for the highest achievers.

On the Bowflex side the SelectTech 560 is the latest model replacing the 552.

Which Fixed Dumbbells to Get?

Dumbbell sets for light lifting are commonly encased in vinyl or neoprene. These are commonly intended for women with average fitness goals.

Sets with weights above 20 lbs. are fundamentally made of cast iron.

Brands are much less significant in this space compared to adjustable dumbbells, as these are comparably simple products to make. That being said, XMARK and CAP offer quality products and are among the best sellers on Amazon.com.

Don’t be fooled by starter fixed dumbbell sets with low price tags, as you’ll easily outgrow these, and the included weights won’t cover what is need to get the most out of P90X or P90X3.

Unless you have a big rack of dumbbells of differing weight right in front of you, it can be difficult manage your dumbbells while following real-time video in P90X. It’s especially challenging if you have limited space as various dumbbells can easily clutter up your workout space.

The best solution for most home gym aficionados is an adjustable dumbbell set. A good set replaces a huge rack of metal dumbbells, while taking up far less space. This makes it a no-brainer for apartment or condo dwellers. The other advantage is speed. Simply plop the dumbbells on the base, make your adjustments, and pull the set back up again.

There are two great options out there: the Bowflex SelectTech 552 set and the PowerBlock Classic set. Both are exceptional choices for P90X. Let’s look at the pros and cons of each so you can make the best choice according to your individual needs.

Bowflex SelectTech 552 Adjustable Dumbbells Review

The Bowflex dumbbell set has a space-age design that is impressively intuitive. At the far end of each dumbbell is a large dial that allows you to increase or decrease the weight as you see fit.

The weight settings go up in increments of 2.5 pounds. This gives you a great deal of flexibility, making the shift to heavier weights more manageable. Each dumbbell can be adjusted anywhere from 5 to 52.5 pounds each (2.27 to 23.8 kg).

The fact you can go up and down in such small increments comes in very handy for P90X. With a traditional small set including a pair of 10s, 15s, and 25s it can be tough to reach the sweet spot while doing a given exercise. Due to the 10 pound difference between the 15s and 25s, most people end up feeling they’ve chosen a dumbbell that is either too heavy or too light.

The dumbbells measure 16” long which might make some P90X exercises awkward. Width on the other hand is perfectly manageable.

Although the design is appealing, come compromises were made to make the set so easy to adjust. The looseness between the plates is the biggest disadvantage to the 552s. The dial plus tiered system makes it possible for the metal portions to tap against each other. This might create a slight rattling sound when you are doing curls.

PowerBlock Classic Adjustable Dumbbell Set Review

This set from PowerBlock couldn’t look more different than the Bowflex SelectTech line. As the name implies each dumbbell resembles a rectangular block. The unique engineering plus color-coded buttons and components give it a future-retro vibe.

Each dumbbell can be adjusted between 5 and 45 pounds in 5-pound increments. In this area, the PowerBlock Classic set is trumped by the more flexible SelectTech 552 model. This limitation is exposed when certain P90X exercises either feel a bit too easy or too difficult. In a way less options are a good thing when you are making a split second decisions about which weight you should choose. With 5-pound increments the selections seem more obvious. Those that value simplicity may prefer this approach over the more exacting Bowflex scheme.

The most impressive characteristic of the PowerBlock Classic set is the solid feel the dumbbells have. This is partially due to the superior construction quality and partially due to the fact that all the pieces are rigidly held in place thanks to the design. You never feel like any plates are too loose as you do with the Bowflex.

Some care must be taken when you are aligning the pins to select the weight you want. It ceases to be a problem when you put it up on a table top or stand. If you are a somewhat clumsy or careless person you may want to get the Bowflex which is very forgiving in this regard.

The Verdict

If you are the type of person that values ease of use and flexibility the Bowflex is for you. It allows you to increase weight in 2.5 pound increments which is very useful when doing P90X. The drawback to this set is the looseness of the plates.

If you like designs that put ruggedness first, get the PowerBlock Classic set. It may look a bit strange to some but the engineering and quality components give it a solid feel. The drawback in this case is decreased flexibility. Adjustments are made in 5 pound increments rather than 2.5 pounds like the Bowflex set.
