VECTOR Products

What is a VECTOR?

Think of the Kayezen VECTOR as elastic resistance training…. reinvented! This single, 3-pound device holds 8 resistance tubes that you can customize according to your needs. With a simple turn of the VECTOR Cap, you “dial in” the number of resistance tubes to pull for your exercise: either 4, 6, or 8 tubes. No more rummaging through your gym bag to switch from color-to-color of bands or tubing….. You have from 10 lbs to over 100 lbs in one VECTOR.  

Using carabiners, one end of the VECTOR hooks to an anchor point: a doorway, heavy exercise equipment like an exercise bike, or a fence at the ball-field. Are you going to take a variety of hand weights or kettlebells with you to the park? Take your VECTOR anywhere! The other end of the VECTOR is for your accessories, like handles.  

What does VECTOR do that I can't do with bands or tubing?

Kayezen VECTOR extends the resistance range beyond what is possible with traditional bands and tubing. Typical resistance bands and tubing deliver ONE level of resistance, often color-coded to reflect ‘easy’, ‘moderate’ or ‘heavy’ resistance. Weight equivalent levels range from 3 lbs to 50 lb+ ‘super bands’. 

With all Kayezen VECTOR Light tubes (5 lb each), the resistance range is 20 to 40 lbs. With all Kayezen VECTOR Heavy tubes (13.5 lbs each), the range is 50 to 100 lbs. And keep in mind that you can customize your VECTOR with a mix of Light and Heavy tubes! Is 100 lbs not enough for you? Pull 2X the amount of resistance with a Dual VECTOR system - working with one VECTOR in each hand. 

Adjusting resistance levels is easy with a twist of the VECTOR cap. If for example you can do bicep curls with 30 pounds but need to dial up to 40 lbs for a military press…. It’s easy with VECTOR. With resistance bands/tubing you need to stop your workout and find a different color band or tube and set everything up.

Working with different body parts is also easy by swapping accessories. Doing leg lifts with typical resistance bands and tubing involves wrapping the band around your ankle, which can be uncomfortable. The VECTOR Cinch Strap has lots of padding to make it comfortable, and you can easily shift it from ankle to knee to thigh….. And even to your arm for upper body work.

Who can use Kayezen VECTOR?

VECTOR can be used by people at all fitness levels. Anyone who is capable of lifting 10 lbs can use a VECTOR. Always consult a healthcare professional before beginning any exercise program. 

What VECTOR Size is right for me? Need help? Take our quiz for your best options.

VECTOR 45 is best if you have space constraints in your workout area, or if you travel frequently and need a TSA-friendly size for carry-on luggage. Otherwise, opt for a VECTOR 60, which gives you 15 inches of additional pull range for your workouts.  

What VECTOR System is right for me?

VECTOR’s Single Mobile System is a great way to start, and is best for those who won’t need more than 100 lbs of resistance. Those who want to take it to the next level should try a Dual Mobile System, which allows you to work out with 2 VECTORs. [This also works for couples who don’t want to share!] With 4 VECTORs, the VECTOR Pro Mobile System is perfect for personal trainers, coaches, and athletes who want instant access to a wide range of single and dual resistance levels.

What are the specs of the VECTORs?

How do I care for my VECTOR?

The outside cover of the VECTOR can be wiped down with a disinfectant wipe or non-abrasive cleaner and soft cotton cloth. Do not use ammonia or acid-based cleaners, abrasive cleaners or paper towels. The internal tubes are housed inside the unit and should be regularly inspected for wear. There’s no need to clean the internal tubes.

Can I travel with a VECTOR?

Your VECTOR system is perfect to take with you! The VECTOR 45 is TSA-compliant for placement in a carry-on. The VECTOR 60 can travel, but you’ll need to place it in your checked luggage. Don’t forget your Door Anchor and accessories for your hotel workouts!


How do I anchor the VECTOR?

First, you’ll need to attach Kayezen carabiners (or any carabiner rated for 12 kN or higher) to your VECTOR. The FIXED loop end (U-shaped) is the end that you attach with a carabiner to a  Kayezen Door Anchor, Kayezen or similar secure wall mounts, chain link fences, posts, poles, or professional equipment such as cable rack and pulley systems or fitness racks. 

How do I attach VECTOR Accessories? 

Look for the VECTOR CAP and the ‘swivel loop’ at the end. Attach a Kayezen carabiner (or any carabiner rated for 12 kN or higher) to your VECTOR, and then attach the accessory to the carabiner. 

How do I change resistance levels with a VECTOR? 

Now that you’re anchored and you’ve attached an accessory, changing resistance is as simple as twisting the VECTOR cap. Always make sure the cap is closed before twisting it to change resistance. 

Start by twisting the cap so that the arrow points to Level 1 (a single horizontal blue line). Pull against the resistance. At Level 1, 4 tubes are engaged. Return to the starting point with the cap closed. Twist the cap to Level 2 (2 horizontal blue lines) and see how that feels. At Level 2, 6 tubes are engaged. Return to the starting point with the cap closed. Twist the cap to Level 3 (3 horizontal blue lines) and see how the resistance increases. At Level 3, all 8 tubes are engaged.

Can I Set Up Any VECTOR to Deliver 10 - 100 Pounds of Resistance?

The resistance range depends on how you set up your VECTOR with a combination of Light/5 lb. and Heavy/13.5 lb tubes. A single VECTOR set with all Light tubing gives 10 lbs (half pull on level one) to 40 lbs resistance. Setting up a VECTOR will all heavy tubes delivers resistance between 50 lbs and 100 lbs. Want something in between? Mix up Lights and Heavies to customize your VECTOR experience. 

What is the process for replacing the tubing?

The replacement of tubing is very simple and takes less than a minute after you get a hang of the process. Check out the video HERE to see how to do it. 

How long does VECTOR Tubing last?

With typical use, your VECTOR tubing should last between 9-12 months. One of the safety features of the Kayezen VECTOR is that the tubing is assembled with Kevlar(R) string inside it. Yep, Kevlar! The Kevlar also serves to give you a stopping point when you’re pulling against the VECTOR resistance. Avoid constantly pulling the VECTOR to this point - take a step toward the anchor point and continue your exercise.

What happens if the VECTOR tubing breaks? 

If a VECTOR tube breaks, the Kevlar string will ‘pop’ out so you’ll know right away that it needs to be replaced.
