When I started doing yoga last October as my health regimen, the men in my family were not interested. They stuck to their choice, working out in the gym. The sons were under a trainor for a while. That was during one summer which of course stopped when school started. Then track and basketball in school became their form of exercise.
I guess they thought yoga was only for women. I don't blame them. More than half of the studio attendees were women. Perhaps that reinforced their aversion for it.
Long story short, I dared the middle son to join me one day. It wasn't instantaneous. It took some convincing. When he finally did, he sweated buckets but liked it. The firstborn followed during his term break. With the two sons being open to yoga, it wasn't long before the hubby joined.
Now, hubby and I do yoga 2-3 times a week. And whenever the sons are in town from university, they set time to join us as well. Yoga has become an interest we all share.
