cheap exercise equipment

Strength training is used to develop the strength and size of skeletal muscles. Properly performed, strength training can provide significant functional benefits and improvement in overall health and well-being. Strength training is often associated with resistance training, and particularly weight training, but there are a number of other forms of training that are also used to develop strength. These include:

Apart from the obvious weights and resistance bands, there are a number of other items of exercise equipment that can be used for strength training:

Isometric, isotonic and isokinetic exercises

These terms combine the prefix "iso", meaning same, with "metric" (distance), "tonic" (strength) and "kinetic" (speed). In "isometric" exercises the length of the muscle does not change, in "isotonic" exercises the force applied to the muscle is relatively unchanged, and in "isokinetic" exercises the speed of movement is constant.

In isometric exercises the muscles flex and hold a stationary position. No movement of a load takes place, and the exercises require little in the way of equipment. An example of an isometric exercise is placing the palms of the hands against each other and pushing.
