The first choice is skipping rope. No matter what technology, you don't need to love too much space. Just stick to it. You exercise all over for half an hour every day.

If you are flexible, you can practice aerobic exercise. Start with simple stretching exercises, kitty stretching exercises can be downloaded! !

With the foundation of practicing yoga, it is very good to persist for a month. Listening to soothing music, enjoying and exercising, my blood pressure is not low.

I hope I can help you.
