An optimum fitness program includes cardiovascular exercise for heart health, stretching exercises for flexibility and resistance exercise for muscle strength and endurance.
To prevent injury when strength training, it is essential you warm up for 5 to 10 minutes with some light cardiovascular activity such as walking, jogging, cycling or rowing and then cool down with some light stretching for 5 to 10 minutes.
To maintain flexibility, incorporate simple stretches into your daily
routine. Stretches should be performed carefully and slowly to
avoid pulling muscles or damaging connective tissues in joints.
