If you prefer slower activities and want a good stretch, try Hot yoga
Most people think that yoga is all about stretching. While stretching is indeed a large part of yoga, it is also about creating balance in the body through strength and flexibility, and creating peace in the mind by forcing the person to concentrate on each pose.
Hot yoga is seen as more challenging compared to other forms of yoga, mostly because it's performed in a studio that is heated up to 40 degrees Celsius and with a high level of humidity.
It may be a struggle at first to remain in the heated room for the full class, but it gets easier over time!
