Hey Mamtha,
Any starting fitness level is the basic fitness which then increases by improving your endurance level, fitness level, muscular strength and flexibility of muscles.
Fitness level can be measured by doing some of the below given tests:
Aerobic fitness tests
Tests for aerobic fitness must use the same type of exercise as the sport in which the individual participates and often will involve a ââ¬Ëtime trialââ¬â¢ format.
Muscular endurance tests
These tests may assess either dynamic muscular endurance (the capacity to repeat contractions) or static muscular endurance (the capacity to sustain a muscular contraction).
Muscular strength tests
Tests for muscular strength should ensure that the muscles being assessed are appropriate and are used through a relevant range of movement, or in the case of static strength at a specific joint angle.
Flexibility/joint mobility tests
Field tests for flexibility/joint mobility range from simple assessments of whether the individual can perform a specific task, to the measurement of joint angles and ranges of movement. Perhaps the most widely used of these is the Sit and Reach test.
