Abuela, you may find some Yoga videos that you would enjoy doing at home. I have several which I bought from Amazon. I work out nearly every day, sometimes more than once, and I don't belong to a gym. I have videotapes for aerobics and strength training and as often as I can I just get outdoors and WALK! The fresh air is as beneficial as the exercise!
I find that whatever I'm doing, whether aerobics or weight-lifting or Yoga, I'm much more likely to stick to a routine if I can do it in the privacy and comfort of my own home. Especially with Yoga. I light a few candles, burn some incense, it's very enjoyable and very relaxing
