The Burto Bungee is a portable exercise system, capable of mimicking almost every exercise that can be performed in a gym and packs into a small bag, roughly the size of a football.


The Burto Bungee works by a method known as Variable Resistance (VR) also known as Curve Linear Resistance. It is the same technique used in Bungy Jumping to gradually slow the jumper down. It has also been used by Power lifters and high performance athletes in increasing strength and explosive power. 

The method is simple once you understand these 3 basics points

  1. Levers and angles
  2. Sticking point
  3. muscle and central nervous system (CNS) overloading

1. Different loading points and angles can greatly change how hard an exercise or lift is. Every exercise has different load zones which change depending on the angle of the levers involved in the lift. To make it simpler they have called them stick points ie. the bottom of a push up, the first part of a chin up or the bottom of a squat.

2. The sticking points is our weakest point which makes it hard to overload our muscles to their full potential. Think of the bottom of a heavy deep squat, once you are past half way up the lift starts to get easier, but if you where to go any heavier your sticking point would not allow you to complete the lift.  

3. Progressive overload is the fundamental principle of muscular development. This is achieved by progressively adding a greater load to the muscle causing it to adapt to better suit its new training stimulus.

Now that you understand these three points, Understanding how VR works will be much easier.


Variable resistance has been known as Linear resistance and curve linear resistance. It gets these names by the linear increase in tension as it is stretched (as seen in the graph below). Burto Bungee technology has a huge curve linear resistance making it much superior to resistance tubes which are currently flooding the market and offers a much more durable and portable alternative to bands and heavy chains. Due to the loading principles explained above, you can see that adding VR to any exercise offers less resistance at the weakest part of the lift and increase in resistance through to the strongest zone. This method has been PROVEN to be safer on the joints as your joints are unloaded at the area of the lift where most injures happen. It has also been PROVEN to increase strength up to three times faster than free weights alone.
