Resistance Training

Resistance training is a form of strength training in which each effort is performed against a specific opposing force generated by resistance (i.e. resistance to being pushed, squeezed, stretched or bent). Exercises are isotonic if a body part is moving against the force. Exercises are isometric if a body part is holding still against the force. Resistance exercise is used to develop the strength and size of skeletal muscles. Properly performed, resistance training can provide significant functional benefits and improvement in overall health and well-being.

The goal of resistance training is to "gradually and progressively overload the musculoskeletal system so it gets stronger." Regular resistance training will strengthen and tone muscles and increase bone mass. Resistance training should not be confused with weightlifting, powerlifting or bodybuilding, which are competitive sports. Weight training is a common type of strength training for developing the strength and size of skeletal muscles. It uses the force of gravity (in the form of weighted bars, dumbbells or weight stacks) to oppose the force generated by muscle through concentric or eccentric contraction. Weight training uses a variety of specialized equipment to target specific muscle groups and types of movement.

Yoga

The Sanskrit term yoga has many meanings. It is derived from the Sanskrit root yuj, "to control", "to yoke", or "to unite". Common meanings include "joining" or "uniting", and related ideas such as "union" and "conjunction".As far as human being is concerned, the term yoga refers to the integration of a person, which we divide broadly into three important aspects the physical, the mental and the spiritual. A personality is a continuum and one part/aspect can not be separated from another. Therefore what effects one will automatically affect the other too. The science of yoga begins to work on the innermost aspect of the personality, the mental aspect by yama, niyama, dhyana, and the physical aspects by asanas, pranayam, and the spiritual aspect by pratyahara, dharana and Samadhi. Major branches of yoga include: Hatha Yoga, Karma Yoga, Jnana Yoga, Bhakti Yoga, and Raja Yoga. Raja Yoga, established by the Yoga Sutras of Patanjali. The sage Patanjali is regarded as the founder of the formal Yoga philosophy.The Yoga Sutras of Patanjali are ascribed to Patanjali, who, as Max M�ller explains, may have been "the author or representative of the Yoga-philosophy without being necessarily the author of the Sutras."Indologist Axel Michaels is dismissive of claims that the work was written by Patanjali, characterizing it instead as a collection of fragments and traditions of texts stemming from the second or third century.
