Stay in this pose in a certain period of time, and the practice can help build up the muscles' memories, so this can help accelerate your practice.
I found that by adding light ankle and wrist weights in my yoga practice, it helps build up my muscle strength, balance and flexibility, also helps build up my body's awareness and consciousness of my movement in my yoga practice. The additional resistance builds up the strength of every muscle in my body. If you want to try this way to practice yoga, start with the lightest weights, and practice with a slow and conscious manner to make sure that you are not damaging your joints.
