I went on to repeat these exercises a further two times, so that I did three sets in total. You should feel this in your traps and lateral deltoids. With straight arms, try to tear the Iso-Bow apart. Keep your arms straight to fully resist this movement and to create the isometric ab exercise.īend forward and roll your shoulders forward. Pull your stomach in and use your abs to curl your upper torso towards your knee. Visualizing your entire shoulder girdle moving backwards can help to achieve this.īend over and position the Iso-bow so that the handles are on each side of your lower thigh. Try to pull the Iso-bow apart using the back muscles (not your arm muscles). Hold the Iso-Bow as though it was a bow and arrow (hence the name). The arms can be repeatedly raised and lowered to put emphasis on different areas of the chest muscle. This causes a peak contraction in the pectoral muscle ie all the fibers in the muscle are at their maximally contracted point during this exercise. The arms are crossed in front of the body so that the hands are pushing outwards whilst trying to pull the Iso-bow apart. Here’s a video of me actually using the device: The device is comfortable to use, and even when applying maximum tension, I never felt the handles dig into my hands. It looks like very good quality stitching and I think it would be impossible to break the device using my own physical strength. The strap is stitched together at the midpoint so that it looks something like a figure eight.
The Iso-Bow itself is well made and consists of a thick nylon strap that feeds through two rigid plastic handles, which have a smooth foam surface. Unless they’re stretched out, you risk becoming less flexible and you could end up pulling or tearing your muscle. I think this is where the term “muscle bound” stems from. I find that the muscles being developed can become tight over time.
#Bullworker x5 exercises plus#
This is a real plus point as I believe that a comprehensive stretching routine should form part of any muscle development program. It also features a number of assisted stretching exercises that can incorporate the Iso-bow. The Iso-Bow comes with a leaflet that details a number of isometric holds that the device can be used for. I decided to write a review on the Iso-Bow. I was further surprised when they sent me one in the post. To my amazement, I was then contacted by John Hughes at Bullworker who suggested I tried out their Iso-Bow. I wrote an article on the Bullworker which can be seen here. For each exercise involving an isometric contraction, once the spring has been compressed to its maximum extent, it is held there for up to 10-15 seconds. This arrangement enables a great number of exercises to be performed. Two straps connect the handles and pulling them apart also forces the handles together, again compressing the spring. By pushing the two handles, at each end of the tube, together, the spring is compressed. It consists of a metal tube that contains a long spring. It’s a simple device that still works perfectly. I’ve trained using an original Bullworker X5 pictured below, which I purchased in the 1980’s. The famous strongman, Alexander Zass used this form of training as his principle method of developing his legendary strength.Īlezander Zass using a training device that looks very similar to a modern day Iso-Bow. This helps to develop the mind-muscle connection.
The high tension involved means you can easily feel the target muscle being worked. The muscles are largely static so you are not moving under load, which can be a cause of muscle sprains and tears. Each “set” or isometric contraction lasts only 10-15 seconds. This form of training is highly effective:
This is not a new form of training and has been around since the 1920s when scientists tied down one leg of a frog and found that it grew stronger as it strained against its bonds. This type of training is called overcoming isometrics. Assuming the wall is well made, there won’t be any movement but your pectoral and tricep muscles will get an amazing workout. For instance, imagine standing facing a wall and trying to push the wall away from you for several seconds (like a vertical bench press). I’m a huge fan of isometrics and have trained in this fashion for several years.įor those unfamiliar with this training concept, it involves pushing or pulling against an immovable object.
