Some pieces of gym equipment are suited solely to a gym environment, because they require additional systems (usually of large expense) to allow them to work. This is an example of that type of equipment, the 'Bodymax Tricep Rope Cable' is an additional attachment to a weighted pulley system which is used for the building of tricep muscles (though other muscles are affected, as with any exercise). I have used this rope cable extensively and recently bought a piece of apparatus which allows me to use it in the home.
Made from a toughened material which is durable whilst remaining relatively easy on your hands - so you don't need to wear gloves whilst exercising with it - the ends of the rope are capped with two plastic balls, rounded at the ends and forming a flat platform where you hands meet them - to increase comfort. At the top of the product is a steel ring (for attaching the relevant machinery) and this is in turn attached to the rope via a hoop which can be moved freely along the rope, though I have only used the product with this being firmly in the centre. Over time, this piece of metal will wear into the rope and be more difficult to move along it - and I generally see this as a bonus rather than an issue as it reduces set up time and allows you to get on with the work out.
The design of this product enables it to be used in a few different ways, key to the building of tricep and chest muscles in the most effective of ways. You can stand upright with the rope attached to a machine in front of you and (gripping each hand at the base of each rope end) pull down with equal strength on each hand. This does your tricep muscles predominantly, but the further you lean forward the more your core chest muscles seem to be affected. This is a satisfactory exercise which makes you feel good, and best of all it can be completed on low weight settings and still have a dominant affect on the body.
Another way you can use the product is by grabbing the rope from behind your back, leaning forward (by bending one knee and straightening out fully the other behind), pulling the rope over your head, bringing it out straight in front of you, before releasing it gradually back and repeating the process again (6-12 times).
I think this product works well, it is a tried and tested method of muscle toning and exercising which is used across most gyms (a testament to its trusted workings). For home use however, it requires the addition of a (usually) large machine of drastic expense which many may find unnecessary. Having this machine allows for the attaching of other exercising equipment of course, so perhaps it is worth it in the long term - it all depends how often you exercise your muscles.
