It's not a stupid idea, it does good to your entire system. But you need to do so safely and for a period of time to see the positive effects. Don't need the head gear if there's a partner with you on the walk. Just one go backwards while the other forward as you hold hands doing it, then vice versa. Walk slowly for 15mins to 30mins.

Good suggestion, I tried it in my living room just now, walk forward for 5 steps then walk backwards another 5 steps, very safe.
