A body’s good health is an indication of good physical exercise and a maintained lifestyle. To be fit, flexibility plays an important role and yoga is the key to achieve that.
Yoga and exercise indeed add more years to your life but if these elements are absent, it can be highly problematic as yoga and exercise keep your heart healthy and define the epitome of a lifestyle. If your body is flexible and healthy, you define that epitome as well.
A few main reasons why people lose flexibility in their body are ageing, sedentary lifestyle, stress, improper posture and movement habits.
Practising yoga is the best way to increase the mobility of muscles and joints. A routine yoga of a minimum of 30 minutes can change your life. Flexibility is not important for oneself but it is important for your partner as well. It helps to give a better experience in bedroom life.
Not only for boosting flexibility but practising yoga will help to give better clarity of life, give strength, and reduce anxiety etc.
There are many different general health benefits of exercising that play a major role in improving your sex life. Exercise gets your heart pumping and improves blood circulation, helps the body move with greater ease, helps to improve stamina. These benefits add value in improving flexibility and thus improving sexual activity.
Other benefits of flexibility are; a greater range of motion, less muscle tension, better posture, reduction in pain in muscles and joints, lower risk of injuries and reduction in stress.
