Not able to find a Tai Chi instructor nearby? Consider practicing Chi Kung instead. It offers similar health benefits as Tai Chi. There are many ways to learn Qigong, including in-person and online instruction, and there are plenty of free videos on YouTube to help you get started.
Practicing Chi Kung improves balance, relaxation, flexibility, breath awareness, anxiety relief, mind-body connection, and overall well-being. It's generally easy to learn, and there are various ways to do so, including through a teacher, books, or videos. For example, I practice Eight Pieces of Brocade daily. It is a simple series of breath cultivation exercises. Some people even claim to feel their "Chi" energy in their first Chi Kung class, likely because the movements can be simple and easy to learn.
In contrast, Tai Chi Chuan involves a series of martial Chi Kung movements that require more details and memorization, making it harder to experience immediate benefits. Unfortunately, many people only learn a simplified, slow, dance-like version of Tai Chi that doesn't offer the full benefits of the practice.
So, if you don't have access to a competent Tai Chi teacher nearby and don't want to travel far, consider choosing Chi Kung for the health benefits you seek.
