Weight machines use gravity as the primary source of resistance, and a combination of simple machines to convey that resistance, to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the weight.
Hydraulic circuit training machines were first developed for The Henley Corporation in the 1970s, and are now becoming an increasingly popular form of exercise. [ citation needed ] The fundamental principles behind these designs are based on fluid dynamics : Force that is applied at one point is transmitted to another point using an ...
A pneumatic exercise machine or pneumatic exercise equipment is an exercise machine or equipment for physical exercise whose function is based on pneumatics, as opposed to or in combination with for example cables or hydraulics.
Commonly used equipment for resistance training include free weights—including dumbbells, barbells, and kettlebells—weight machines, and resistance bands. [43] Resistance can also be generated by inertia in flywheel training instead of by gravity from weights, facilitating variable resistance throughout the range of motion and eccentric ...
A selection of home exercise equipment: yoga blocks, yoga mat, dumbbells, pull-up/chin-up bar, push-up handles and gloves. Exercise equipment is any apparatus or device used during physical activity to enhance the strength or conditioning effects of that exercise by providing either fixed or adjustable amounts of resistance, or to otherwise enhance the experience or outcome of an exercise routine.
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present.
Isometric exercise devices perform exercises or strength test using static contraction of a muscle without any visible movement in the angle of the joint. This is reflected in the name; the term "isometric" combines the prefix "iso" (same) with "metric" (distance), meaning that in these exercises the length of the muscle does not change, [1] as compared to isotonic contractions ("tonos" means ...
The mechanical advantage of a simple machine like the wheel and axle is computed as the ratio of the resistance to the effort. The larger the ratio the greater the multiplication of force (torque) created or distance achieved. By varying the radii of the axle and/or wheel, any amount of mechanical advantage may be gained.
