To everything, there is an interval
I'm a wogger. What that means is I mix jogging and walking in a regimented way i.e. I jog for three minutes, walk for two, then repeat the process. It's an easy way to get into distance running, and running guru Jeff Galloway swears it can even make you faster. I can't vouch for that, as I'm a start-slow-taper-off kind of girl. But I do feel it gives you a better overall workout as walking tends to work the hamstrings and butt and running tends to focus more on the quadriceps.
Last year I started a wogging club called the Half-Crazy Marathon Club. We train for and travel to half-marathons. My club is mostly made up of women over 30, whom I believe are especially well-suited to the interval mindset. Women of experience know "this-too-shall-pass" and most can stand anything if they know they'll eventually get a break (which explains our ability to endure labor and the occasional bad marriage.)
Men, not so much. In fact, I believe men fall victim to the middle-age crazies because they can't get the hang of the "seasons" of marriage. They look at their wives' focus on the kids or career as permanent, so they seek out that young chick who will dote on them, only to see that devotion wane when she becomes a mother or gets on the career track herself. Meanwhile, wife No. 1 has emerged from the "season" of mommy and/or career concerns and is now ready to return to the roots of her marriage.
Delayed gratification. We understand it. This too will get better.
