Band Ratings & Specifications

Tension Ratings Chart

Tension ratings




How the ratings are recorded...

The "Average" rating is the minimum rating that is easily achievable for all exercises and is taken with the bands stretched to around 2x their resting length, so a bicep curl would be a good example of an exercise that will produce around the average rating. By using a wider foot spacing on the band or standing further from the anchor point, you can easily achieve a higher resistance than the average.


The "Overhead Press" rating was taken at the very top of an overhead press by a person of average height (about 5ft 7") with feet close together. During the overhead press is about as far as you will ever stretch an exercise band, so any tension that may be created beyond that point is irrelevant and would be both unfair and pointless to record.


Using these 2 ratings gives you a better and more realistic idea of how much resistance each band will offer you, and is not misleading.


A 21 Kg rated band will produce AT LEAST 10.5 Kg on each side when using a handle on both ends, just like a 21 Kg barbell would have 10.5 Kg of weight on each side. The wider apart your feet are, the higher the tension will be, every inch makes a noticeable difference in tension but also reduces how far you can stretch the tubing and sleeve. You can also attach both ends of a band to the same handle and use it like a single dumbbell, this will give you the total rating on one side of your body, e.g. 21 Kg on one arm.


NOTE: As with ALL exercise bands things such as your height, limb length and posture will effect the tension. E.g. a taller person may achieve a higher rating, a shorter person may achieve a lower rating. If you are quite short you can put more resting length between your feet to make up for this.


Ratings are rounded off to the closest 0.5 Kg for the sake of simplicity, e.g. if a band is 20.2 Kg it will be rounded down to 20 Kg, if it is 20.4 Kg it will be rounded up to 20.5 Kg. Because the tension of an exercise band constantly changes as it is being stretched and relaxed, rounding off really makes no difference as there is no such thing as a fixed tension with resistance bands anyway, which is also why the bands are labeled with words such as "Heavy"and not fixed numbers.


Band Length

All bands are approx 139cm in length including the rings. They can stretch up to approx 5 metres before the sleeve will halt the band.


Taller users must use just one foot on the band for the overhead press OR Ankle straps can be added between the band and the handle to add another 40-50 cm to the length. You can also add a length of chain or cord etc between the bands and the handle if you wish, to make them as long as you want if you need too.This will not void the warranty. You can also cut the sleeves off, but this will void the anti-snap warranty.
