Yes, online yoga https://www.julianalucky.com/ classes are available, and physical activity is beneficial at any age and in almost any condition. But you should not strive to immediately do the same as the teacher or flexible nymphs do in photos on social networks.
It is important to see your body for what it is and be honest with yourself. No matter how much determination and will you have, there are objective facts: with age, the volume of muscle tissue decreases, which means that strength exercises will be more difficult. Ligaments and tendons become less elastic, and fascia less mobile. If you spend most of the day sitting in front of a monitor, the condition of the connective tissue will not allow you to quickly develop flexibility and rebuild movement patterns. If there is excess weight,
then during classes the pressure can quickly increase, and if there are problems with the autonomic nervous system, it can also fall quickly.
You should not treat these factors as shortcomings or problems that need to be addressed. In any case, your body is worthy of respect and care – right now, and not when it loses weight, becomes strong, flexible, etc. This is just the starting point from which you start moving. This approach helps to remove unnecessary mental stress from your practice, which means it reduces the risk of injury and burnout.
Regardless of the format of classes, online or live classes, you are responsible for your practice and the condition of your body.
Only you choose the limit to which you go into the asana, and the duration of its retention. Only you decide with what intensity and regularity you are ready to practice. Only you know why you come to yoga and how deep you intend to dive into the process of exploring your body and your capabilities.
