I have never tried sleeves and I find it cheating.
Cheating?
1) Powerlifting Meet
If the rule allows it in a Powerlifting Organization, how is it cheating?
2) Training Session
If someone is using them during a Squat Training Session, how is that cheating?
Accommodating Resistance
Knee Sleeves and Knee Wraps fall into the the category of Accommodating Resistance with Ascending Strength Curve Movement, such as the Squat.
The Ascending Strength Curve
In Plain English this means the Movement is hard in the bottom part of the Movement and gets easier the closer you get to lock out.
Accommodating Resistance
Attaching Bands and/or Chain to a Squat ensure the mucles in a Movement are loaded through a Greater Range of The Movement; which is top end.
Reverse Band Loading
Hannging Band from the top of a Power Rack to the bar in a Squat ensure loading of the muscle throughout the Full Range of The Movement.
Knee Sleeves and Knee Wraps elicit Reverse Loading; enabling a lifter drive out of the hole with more weight, increasing the loading of the muscle in a Greater Range of The Movement.
Dr Gideon Ariel's Research
Ariel's research determined that regardless of The Movement (Ascending, Descending or Bell Shaped Stregth Curve),
only 30% of The Exercise was OverLoad. The key to for Strength and Hypertrophy is to OverLoad the muscles.
The remaining 70% of The Movcement is UnderLoaded. While some result are obtain in the UnderLoad part The Movement, it is dramatically less...meaning the remaining 70% of The Movement does not optimally develop Strength.
he word is that you can get at least 10kg when you buy right size, that is a workout itself to pull on..,when someone else is tying them on with all their strength.
At Least 10 kg Increase
I purchased the SBD Knee Band in one size smaller.
It take a little effort to get them on. However, I get them on in less than 30 seconds.
The tight SBD Knee Sleeves allow me to possibly Squat around 10 lbs/5 kg more.
"Never Tried Them"
It is hard to comprehend something that you have never tried.
Like most, my initial reaction to anything that I am not familiar with and have no personal experience with is questioned and doubted; as is should be.
I then resolve myself to implementing it so that I have practical experience with it.
The Bench Press Sling Shot Post
The discussion of The Sling Shot for Bench Press Training somewhat similar.
The greatest blow back was form individuals who were unable to understand the Training Effect it Elicited with The Sling Shot; Accommodating Strength Training, providing a Post Activation Potentiation Training Effect, etc.
