## Description

desertcart.com : Exxentric kBox Active (Small Harness) : Sports & Outdoors

Review: Do not underestimate this piece of equipment - I am an athlete in my mid 40s and strength training has been a huge part of my life for thirty plus years now. My training has evolved over the years, due to changes in priorities and of course the injuries that are inevitable, when you choose this lifestyle. I am currently training with the mindset of strength and conditioning. My daily workouts consist of 30-45 minutes of constant movement, with an emphasis on variety. After doing extensive research on the kBox4, I decided that it would be a great investment for my garage gym...man was I right!! This thing is awesome and I really can't compare it to any other sort of resistance that I have ever experienced. This machine offers up a slow, steady form of constant resistance...that forces you to use perfect technique. Using momentum is completely out of the question, which really stresses the muscle groups that your are targeting. I have been using this thing for RDLs, rows, overhead tricep extensions, curls, high pulls and my favorite...belt squats!! I am amazed at how well this movement targets my quads, without any strain on my lower back. I am extremely satisfied with my purchase and plan on using this this for years to come. Thanks for an awesome product!!
Review: Unique form of accessory exercise - I was lucky enough to have many desertcart points to use to buy this machine. Flywheels focus on the eccentric portion of an exercise. This is a fairly simple device that one can use for many accessorize movements. I would say this would not replace weights or traditional Bodyweight exercise. My machine came with a meter to measure output, but it is not an exact measurement like weights. One can use this for a quick warmup or a 10 minute upper or lower body workout. Flywheel exercise is unique and niche. I was a complete novice to this form of exercise. I am satisfied with the purchase. It is the form of exercise used in space as the inertia is indeprdent of gravity. I would recommend trying a machine before buying as they are expensive for so simple a mechanism.

## Features

- Package includes kBox unit, 2 Large Flywheels, 1 Medium Flywheel, Hip Belt, kGrips, kBar and Ankle Cuffs
- PACKAGE INCLUDES: kBox Active unit (30 in W x 20 in L x 8.5 in H) 32 lbs, 2 Large flywheels, 1 Medium Flywheel, Hip Belt (select size), kGrips (pair), kBar and Ankle Cuffs (pair). Additional accessories are available at our desertcart Exxentric Store Front.
- HOW IT WORKS: The kBox4 Active uses a flywheel to create variable and unlimited resistance in your strength training. The more effort you put into the movement against the flywheel (inertia) the more challenging it becomes and vice versa. Your body will stay engaged for the entire movement of the exercise, during both the shortening (concentric) and lengthening (eccentric) portions of the exercise.
- BENEFITS: Get a full body workout with just this one multi-exercise device. Ability to safely and efficiently workout without the added weight of a barbell. It has a small footprint that saves space within your home gym or studio and can easily be taken outside to workout anywhere.

## Questions & Answers

**Q: I read a review that said they can do high pulls on the kbox 4 how is that performed?**
A: Thanks for your questions, I have attached a video along with this answer. Like any exercise on the kBox, you want to start by putting on a flywheel(s) on the kBox and then set the correct length of the drivebelt for your chosen exercise. When you set the length you want to set it for the end position, so for a high pull the belt should be long enough so you can go to about shoulder height. After setting the length, spin the wheel to get started and then pull in a controlled fashion to accelerate the flywheel(s) until you reach the top position that you previously set. At that point the kBox will reverse the movement and start pulling you down. Resist (decelerate) the flywheel and when you reach your starting position then do it all over again. You can find a extensive exercise video library on YouTube using this link: https://www.youtube.com/watch?v=zu4NH9STQ2c&list=PLCV6VVd5NMUJAlGYThqfUst7Kcl_5N6Ab&index=18

**Q: Between this and your lite what’s the difference and mainly using this for sqauts and deadlifts will**
A: The kBox4 Active and Lite units are both great units for performing squats and deadlifts.
There are two significant differences between these two models: 
1. The kBox4 Active can hold a maximum of 2 flywheels; kBox4 Lite can hold up 4 flywheels. Flywheels determine the amount of inertia that you work against.
2. The kBox4 Active does not have a built-in kMeter like the kBox4 Lite unit. The kMeter measures and records your force output and more throughout your workout. 
The kBox4 Active is the only unit we sell on Amazon, and designed for home users. The kBox4 Lite unit is designed with advanced features and is not available on Amazon.

**Q: How can I know the right size for me if I am 6 ft or 181 cm ?**
A: Our Hip Belts are adjustable and you can pick the best size for you based on your hip circumference. The Medium-Large size has an inner circumference range from 32 to 51 inches, whereas the Small-Medium size has an inner circumference range from 23 to 43 inches.
