Rotary torso machine
The twister double machine
The twister double machine is a simple version of the rotary torso, that will isolate and develop the side abdominal muscles, the obliques.
The development of a strong and attractive mid section will be of paramount importance for many trainers at any gym, and as such, this obliques trainer will be a valued addition, and is a must, for any comprehensive gym environment.
The rotary torso is quite a simple device, and as such is a great value piece of gym equipment, and the benefits of the machine to the user, are much higher than its low price would suggest.
The machine is composed of heavy gauge steel, and is designed for years of reliability and durability in a professional gym environment.
This machine will be a very popular station at any gym.
The muscles worked by the twister double machine
The main muscles worked during the execution of the obliques twist on the twister double machine are the obliques. The central abdominal muscles will also receive secondary benefit from the twister exercise.
Appearance and dimensions of the twister double machine
The twister double machine is a simple device, with two stations for performing the obliques twist. One of the stations on the twister double machine offers a standing platform for the abdominal twist, and the other a seated. The muscles worked will be the same, but the machine offers a choice for users, and they can decide how they prefer to perform the muscle movement.
The machine is composed of heavy gauge steel in white, with seated pads and a non slip foot pad in black. The two stations (seated and standing) are located opposite from one another, and two people can use the machine at the same time. There are hand grips at chest height that allow the users to keep their upper bodies stationary, as they twist with their lower torsos. The standing twister station has two steel pegs that allow for the addition of weight, and thus the intensification of the exercise.
The dimensions of the machine are 155 cm x 134 cm x 55 cm, and the weight of the unit is 42kg.
How to use the twister double machine
The twister double machine is very user friendly, and can be quickly mastered by even novice users; but with the possible addition of extra weight plates, the device offers a challenging and rewarding exercise for even the most experienced trainer at any gym.
The obliques twister can be used safely without the need for a spotter or assistant.
Approach either the seated or standing platforms, and get comfortable, with a secure two handed grip on the hand restraints. You should keep your shoulders square with these handles as you perform the exercise and keep the twisting in your abdominal region for best effect.
Slowly and steadily rotate your legs and lower body to the left, as far as is comfortable. At the outside of the range of motion, pause for as count of two, and give your obliques a concerted clenching. Proceed with the exercise all the way to the right as you can comfortable go, and again pause, and give your obliques a clenching.
Perform as many repetitions as you can until you approach muscle failure, and for best results, perform three sets of repetitions per training session.
If you are adding weights to intensify the exercise, make sure that you can still perform the range of motion with a motionless upper torso, and a slow and controlled motion throughout the execution of the exercise. If you cannot, then you should reduce the weight. Good and controlled form will always produce better results than heavier weight and incorrect form.
Incorrect form can lead to injury
The double twister machine is very safe, and the likelihood of injury on this machine is quite low. You can safely use the double twister device without an assistant.
You should take it easy for the first few training sessions on the double twister. Your obliques will need to adjust to the new muscle movement, and will likely feel quite sore for a couple of days after you work them, until you grow accustomed to the exercise.
The greatest risk of injury while performing the double twister is through insufficiently warming up. If you approach the obliques twist with “cold” muscles, you are at a much greater risk of a muscle strain or a muscle tear. These will be quite painful, and could possibly impair your mobility. Warm up to avoid a muscle strain or tear.
A great way to ensure that you are limber and appropriately warmed up for the exercise is to perform an initial set of the obliques twister with a very low weight, and a slow and limited range of motion. This will prime your muscles for the more strenuous sets to follow.
Variable techniques for the double twister machine
The double twister machine will enforce correct form throughout the execution of the range of motion, and will produce good isolation and development of the obliques, but is not well suited to variations in the execution of the exercise.
You can vary the results achieved through altering both the amount of weight added, as well as the number of repetitions performed. If your goal is to increase both muscle strength and size, you should perform fewer repetitions with a greater total weight; and if your goal is to shape and tone, then you should perform a greater number of repetitions, with a reduced total weight.
Why you should consider the twister double machine
The twister double machine is an excellent gym device for the isolation and development of the obliques. Many trainers will consider abdominal training to be a priority; and as such this station is always popular at any gym.
Every comprehensive gym requires a machine for the effective isolation and training of the obliques.
The machine is quite simple, but is constructed from heavy gauge steel, and is designed for years of usage in a busy gym environment.
The machine is very user friendly, but offers a potential range of weight that will keep it challenging enough for even the most experienced trainer at any gym.
The twister double machine is an excellent value piece of gym equipment.
