It is moved down the cylinder by the handle as it is compressed. There are literally dozens of exercises that can be performed with the Bullworker, each targeting specific body parts such as the chest, back, arms, shoulders and legs.
The Bullworker was invented by Gert F. Kolbel in the early s and since then over 9 million units have been sold. The original design was called a Tensolator and went through various design changes, one of which was the highly popular Bullworker X5.
The modern version has evolved into a very ergonomically designed unit that is very comfortable to use. The Bullworker X5 can be used both isotonically — involving movement — or isometrically — with static contractions. Regular weight training involves Isotonic contractions.
The weights are raised and lowered in a rhythmic movement. Typically each muscle moves from a fully extended position back and forth to a fully contracted position.
The spring actually gets harder to move the further it is compressed. This mirrors the way the muscles of the body operate: the more they are contracted the more force they are capable of exerting. You can prove this yourself by performing a barbell curl with your arm fully extended. The amount of weight that you can move will be much lower compared to when your arms are bent at right angles. The movement of the Bullworker becomes harder as the muscle contract and are able to generate more force.
This makes a very effective workout for the muscles that are targeted. At a certain point, compressing the spring any further will become impossible and the muscles can be allowed to relax enabling the Bullworker to return to its original position. Avoid any time for the muscles to recover fully, the Bullworker is again compressed. This pattern is repeated until either the desired number of repetitions is reached or the muscles are simply too tired to continue.
Isometric exercises involve the muscles contracting but they do not change length and consequently there is no resultant movement. Imagine pushing against a solid concrete wall with all your might. Isometric training is a highly effective form of training for the following reasons:.
With the Bullworker, you can compress the handles as hard as you can and hold them statically in place for 7 — 15 seconds.
Alternatively, the straps can be pulled apart and held in place for the desired amount of time. The Bullworker can be used for dozens of exercises some of which can be seen in the video below:. The Bullworker X5 is a very well built piece of kit. The design has improved since the Bullworker X5 originally came onto the market. It now features ergonomic handles and, in addition, it comes with a selection of springs. Changing the springs allows for a greater compression enabling a more complete isotonic contraction.
It also allows you to easily progress your level of strength. Once you can fully contract the Bullworker using the weakest spring, you can move on to the next level of spring.

Each contraction typically lasts from 7 to 15 seconds. This constitutes one set. With isometrics you can feel the tension in the muscle being affected. The best isometric exercise equipment to maximise your training. Is headgear bad for sparring?
