The Perfect Accessory for your Power Bands

Heavy resistance bands are great to use on their own by simply attaching them to a post or door, or just anchoring them under your feet, hands, or around your back.

But what if I told you that by adding a few accessories you could add even more exercise variations to your workout routine. Here are a few accessories that I highly recommend using together with loop style heavy bands:

Clench Fitness handles for heavy bands

My newest find, the Clench Fitness heavy band handles are specifically designed to quickly attach to any power band. These handles will add a whole new dimension to your power band workout by providing you with a grip similar to using handles on a cable pulley machine.

This door anchor by BOSS can be used under a door, over, or on the sides of most doors.

Attach this bar to your power bands to perform squats, biceps curls, triceps extensions and more.

Heavy Band Resistance vs Free Weights

There are various differences and similarities when comparing heavy bands to free weights when it comes to resistance training. Both have their advantages and disadvantages. However, looking at the chart below, it appears that heavy duty resistance bands may have a few more advantages.

Is that to say that power bands are better than free weights? Absolutely not. It only means that heavy bands might be a better choice for your particular workout routines and fitness goals.

Top Benefits of Using Heavy Bands for Resistance Training

Low Impact on Joints
High intensity bands are very low impact and with the constant tension almost forces the user to use even and steady movements throughout the full range of each exercise. This makes these bands ideal for rehab, mobility, power, and performance exercises.

Variable Resistance
Each power band has variable levels of resistance. Resistance increases as bands are stretched. Resistance can be controlled by how far down you are gripping the band, or how far apart your feet are when anchoring the band.

Push Up Assistant
Now anyone can do pull-ups. Even If you can’t perform one single pull up, these power bands will have you doing multiple pull-ups instantly. Just start with the heaviest resistance band and work your way up.

Constant Resistance
Constant resistance keeps the muscles working throughout the entire range of motion for each exercise. It also helps develop stabilizers while increasing strength and decreasing muscular imbalances.

Portable & Compact
When compared to weights, loop style heavy bands are very lightweight and compact. That said, this makes them ideal to carry around in a bag when on the go, or store away in a drawer at home when not in use.

What Can Loop Style Heavy Bands Do For You?

In addition to the previously mentioned benefits these bands have to offer, let’s take a look at what these bands can do for you as an athlete, bodybuilder, or anybody who wants to improve their health in various ways.

  • Ideal for full-body workouts
  • Increase your speed, agility, and flexibility
  • Help improve posture issues with functional exercises
  • Increase strength and build muscle
  • Assist with pull-ups
  • Burn fat with light resistance & high rep cardio routines
  • Use for stretching and warming up
  • Add to a squat machine or power rack for added resistance such as:
    • Banded squat and press
    • Banded bench
    • Banded rack pull
    • Banded deadlift

Larger bands with tension levels between 50 lbs and 150 lbs are ideal for obtaining maximum resistance when used together with leg presses, squats, deadlifts, and even shoulder shrugs to name a few. Simply by adding these bands to a barbell while connected to a bench or squat rack, you can safely increase the intensity of your workout without adding extra weights to the bar.

The best heavy resistance bands to use for cardio training and stretching are bands with resistance levels below 50 pounds. Since heavy bands have linear variable resistance, it is easy to tweak the tension levels by a few pounds for any band by simply gripping the band higher or lower, or widening your grip or foot support.

With that said, find a good quality set of heavy bands, make the purchase, and see for yourself how these bands can help you reach your personal fitness goals.

They are awesome add-ons to help make your exercise routines even more productive when using power bands.
