Fear not my friend! I have just the answer for rickety. They are fun. They are daring. You don't have to go to the gym! You can do it right there, in your own living room. Yoga-swings! They work wonders for all parts of ricketyness. They bring out parts you had forgotten you even had! They work wonders for your bravery and spontaneity. I strongly suggest you have a spotter or a partner while engaging in such exercises. They are hard to get into by yourself. Sometimes you need a push to get swinging. But once your there, they are a blast!
