First and foremost, dance. Your own dance form and other forms, try to explore all different kinds of dance.

Other physical activities that I find valuable are yoga, pilates, weight lifting, HIgh Intensity Interval Training, running, swimming, badminton. To make the most of your learning experience, stick with a physical activity for at least a year, especially if you don't feel like it is a good match for you. For example, I hate downward facing dog (a yoga pose) and almost gave up yoga because the move didn't work for me. Then I realized that I needed more flexibility in the chest and shoulders and that's exactly what the pose does.

If the physicial activity makes you miserable as a while, try to write down how you feel and why. Take this lesson with you in future projects. For example, I tried snowboarding but it never worked for me. After contemplation, my fear for injuries and heights was too big to overcome. I take that with me when choosing new physical activities.
